   Willow Flycatcher (Empidonax traillii) - WIFL (recent eBird sightings, view CBRC records, range map
)

  1. Piute Sabine's Gull LINK
    DATE: Sep 10, 2018 @ 5:51pm, 9 day(s) ago
    Very young bird with scaling on its back, a pale face with a black bill and yellow legs. It is incredibly windy up here, I cannot get photographs. I am at the Ducks Unlimited Ponds looking east from the main road that runs kind of north and south. Thank you,
    Dick Norton, for telling me about the Cattle Egret, which I did see and get a photograph of, at this same pond. The Cattle Egret is hanging out with Mallards (I guess he is trying to pass the duck test) and when I got out of the car to take his picture he
    flew off with the Mallards and disappeared in the reeds.
    
    The group that was up here during the daytime, unrelated to my visit, never saw the Pectoral Sandpiper at Duckbill, but it was here in the afternoon when I came up here. I am going to go back to Duckbill before I leave, to see if I get lucky and find the Stilt
    Sandpiper.
    
    Earlier this afternoon I stopped at Apollo Park for an hour and I only saw two Willow Flycatchers and a small number of Brewer's Sparrows among the Bell's Sparrows, and no warblers or other sparrows.

  3. Willow Flycatcher at Crystalaire LINK
    DATE: Aug 9, 2018 @ 5:30pm, 41 day(s) ago
    A Willow Flycatcher showed up in our front yard in Crystalaire this morning. Also a Rufous Hummingbird. The link to my eBird checklist with pictures is https://ebird.org/view/checklist/S47750170

  5. Re: [LACoBirds] Continuing Brant, Pacific Loon, Willow Flycatcher & more (San Pedro) LINK
    DATE: May 29, 2018, 4 month(s) ago
    The Pacific Loon also continued at the same location as of 11:12am today
    (in fact at that time, it was floating alongside the Brant, demonstrating
    that they are the same length). And to correct my earlier comment about
    the beached Red-throated Loon: it's in first-summer (immature) plumage,
    not adult nonbreeding.
    
    The other local Ash-throated Flycatcher also continues. One was at
    Lookout Point Park on May 20 (11:07-11:20am) and May 25 (1:50pm), and one
    was at Shoshonean Road on May 24 (5:11pm) and Cabrillo Marine Aquarium
    parking lot on May 29 (10:53-10:56am).
    
    And concerning my comment about Black Skimmers, "each one has an
    audibly different voice", I should add that I've noticed the same
    thing for most bird species. The reason it came to mind for skimmers is
    that I've been reporting lots of banded ones, and was thinking about
    potential alternative ways to track individuals over time.
    
    Another little note I'd like to add: The Double-crested Cormorants at
    Cabrillo Youth Camp have been very vocal for the past week or more. I
    think I was birding for years before I ever heard one at all. I may not
    still have ever heard a Brown Pelican vocalize.

    I just went down to Cabrillo
    Beach, and as of 9:15am, the Brant continues, this time on the inner
    beach (not the scout camp beach) along with a flock of Black Skimmers,
    California Gulls, and Western Gulls. I also just took a beached
    Red-throated Loon (adult in nonbreeding plumage) from the inner beach to
    IBRRC. I haven't checked yet if the Pacific Loon is still here, but it
    seems healthy; it looked very clean when it showed its belly yesterday
    evening, and was putting its head underwater to look for prey (though
    didn't dive while I watched).
    
    And a third thing I forgot to include: An Olive-sided Flycatcher was
    perching in trees both small and large on the west side of the southern
    stretch of Shoshonean Road (west-adjacent of the Salt Marsh), on May 22
    from 9:02am to 9:18am.

    First of all, I forgot to
    include three things: A Nashville Warbler was in my backyard near
    Cabrillo Beach on May 23 and 24, and a male Phainopepla was at the Greg
    Smith Conifer Grove again on May 20 at 12:10pm. And, for a few days
    starting May 15, there were singing Swainson's Thrushes all over the
    Cabrillo area (in a tree near the dirt ramp down to Cabrillo Beach; in a
    tree in the Marine Aquarium parking lot area; all along the top of the
    slope/cliffside on the west side of Shoshonean Road), just like the
    singing Black-headed Grosbeaks; both species are still around here, but
    not singing anywhere near as much as they were during those few
    days.
    
    Secondly, I wanted to add that of all the Japanese White-eye audio
    samples on xeno-canto.org , the only
    ones that actually sounded like ours here were two recordings made in
    Orange County. None of the recordings made in Japan sounded like ours. I
    am inclined to believe that the identification of Japanese White-eye is
    incorrect, and they're in fact some other species of White-eye (or at
    least, a subspecies of Japanese White-eye that is vastly
    under-represented on xeno-canto); the call sounds like an innate call,
    which wouldn't need to be learned, so captive-raised birds should do the
    same calls as wild ones in their native habitat, right
    
    Photos still to come later.

    Yesterday and today (May 27-28) both a Black Brant, and a Pacific Loon in
    absolutely full breeding plumage, were at Cabrillo Youth Camp (during the
    late afternoon, at least, when I looked on both days). The Brant spent
    time both on water and on shore. Both birds can be seen from the boat
    launch dock which is southeast-adjacent to the salt marsh (Salinas de San
    Pedro).
    
    On both May 23 and 25 a Willow Flycatcher showed up in my backyard,
    giving me a new yard bird. (It's possible they weren't even the same
    individual.) Other flycatchers have been especially abundant as well;
    Pacific-slope Flycatchers have been as numerous as I ever remember them
    being here, and Willow Flycatchers might be even more numerous than
    they've been before in my experience (i.e. since 2006). I saw an
    agonistic territorial encounter between two Willow Flycatchers for the
    first time (in my backyard) and one of them made an agonistic call
    sounding identical to a Say's Phoebe agonstic call (a call that many
    Northern Mockingbirds include in their song repertoire) a call which I
    think is most notable for its peculiar lack of
    "aggressive-soundingness" to human ears, in contrast to the
    agonistic calls of most other species. And I have found two Ash-throated
    Flycatchers recently at different local spots, one of them continuing,
    when Ash-throated Flycatchers have been mostly absent in my area for
    years.
    
    The Warbling Vireos are still present in force. I've had at least 6 at
    once in my backyard at times, and they often sing.
    
    I have observed proof of Orange-crowned Warbler nesting success in the
    Salt Marsh / Shoshonean Road area. An Orange-crowned Warbler, whose song
    I recognize from at least one year ago at the same location, fed a
    begging juvenile, and I recognized his identifying physical features from
    having filmed him singing earlier. And at another spot, an Orange-crowned
    Warbler sang for vast swaths of the day (also with a unique recognizable
    song), every day for weeks, and suddenly a few days ago stopped singing
    and started hanging out with a second Orange-crowned Warbler very
    suggestive that this pair are nesting as well.
    
    At least two "Japanese" White-eyes have been quite consipicuous
    in the area, with a Hutton's Vireo like call, showing up often in the
    Cabrillo Marine Aquarium parking lot... and today for the first time I'm
    aware of, in my backyard near Cabrillo Beach. (They usually show up as a
    pair together, which for a while made me think there are two in the area,
    but in retrospect the frequency with which I encounter them suggests
    there are quite a bit more than two.) I put "Japanese" in
    quotes because I don't understand why virtually everyone is identifying
    these as Japanese White-eyes. I looked at the various species of
    White-eye (they are numerous) and a large number of them look virtually
    identical I couldn't find any distinguishing characteristics by looking
    at photos. When listing to samples of a large subset of White-eye species
    on xeno-canto.org , I couldn't find
    any that actually matches the Hutton's Vireo like call I most often hear
    from the ones here and in Orange County. Certainly, the Japanese
    White-eye audio samples sound nothing like the ones here. So why do
    birders identify them as Japanese White-eye instead of
    White-eye sp.
    
    Black Skimmers have been sticking around every day lately at the Cabrillo
    Youth Camp shore. They're very vocal whenever another skimmer comes in to
    land with them, and each one has an audibly different voice. I got to see
    a behavior I'd never seen before from this species a fish display. A
    skimmer held the fish in his bill, as if to entice the other skimmers,
    but none of them proved worthy of it (all who tried to take it were
    denied) and eventually he ended up eating it himself.
    
    On May 24 I had my first-of-season Least Tern at Cabrillo Beach dive and
    catch a fish in the water just outside the salt marsh.
    
    A Heermann's Gull adult in breeding plumage was at Cabrillo Beach today
    at 5:33pm. I haven't even seen an immature one since May 12, and hadn't
    seen an adult since March 24.
    
    I will post photos later.

  7. RE: [LACoBirds] Continuing Brant, Pacific Loon, Willow Flycatcher & more (San Pedro) LINK
    DATE: May 29, 2018, 4 month(s) ago
    David, Your questions about the identity of the white-eyes that are increasingly well-established in Orange and se. Los Angeles Counties are valid ones. Bear in mind
    that Japanese White-eyes (Zosterops japonicus) are geographically quite variable, and I wouldnt doubt that there is some geographical variation in vocalizations as well. Our birds seem to match most closely Japanese White-eyes from mainland China (Z. j. simplex);
    these are not the ones that are in Japan or established on the Hawaiian Islands. But some subspecies of Oriental White-eye (Z. palpebrosus) are closely similar in appearance to some Japanese White-eyes, and youre correct to have some skepticism regarding
    the species identification of our birds. We hope this can be resolved soon we have one specimen here at the Natural History Museum (salvaged from Orange County), and our colleagues at the Moore Laboratory of Zoology are hoping to have the results of their
    DNA analysis of that specimen soon. If you or anybody run across a dead or moribund white-eye, please make certain it gets to us to help document our incipient populations. To my ear the calls Ive heard from white-eyes in Orange County and in Long Beach seem to match fairly closely some of the calls of Japanese White-eye available
    on Xeno-Canto. Unfortunately, recordings of Oriental White-eyes on Xeno-Canto are not available on the web site. As Xeno-Canto explains, Some species
    are under extreme pressure due to trapping or harassment. The open availability of high-quality recordings of these species can make the problems even worse. For this reason, streaming and downloading of these recordings is disabled. We have been validating eBird entries of Japanese White-eye from southern California in order to establish that as the working hypothesis regarding
    identification. If youre searching for white-eye sightings, search on that species but also on Zosterops sp. (white-eye sp.), since many observers understandably are only comfortable entering sightings at that level of certainty. Bottom line: get recordings,
    and get specimens, and well be able to figure out for certain what we have. Kimball

    song), every day for weeks, and suddenly a few days ago stopped singing
    and started hanging out with a second Orange-crowned Warbler very
    suggestive that this pair are nesting as well.
    
    At least two "Japanese" White-eyes have been quite consipicuous
    in the area, with a Hutton's Vireo like call, showing up often in the
    Cabrillo Marine Aquarium parking lot... and today for the first time I'm
    aware of, in my backyard near Cabrillo Beach. (They usually show up as a
    pair together, which for a while made me think there are two in the area,
    but in retrospect the frequency with which I encounter them suggests
    there are quite a bit more than two.) I put "Japanese" in
    quotes because I don't understand why virtually everyone is identifying
    these as Japanese White-eyes. I looked at the various species of
    White-eye (they are numerous) and a large number of them look virtually
    identical I couldn't find any distinguishing characteristics by looking
    at photos. When listing to samples of a large subset of White-eye species
    on xeno-canto.org , I couldn't find
    any that actually matches the Hutton's Vireo like call I most often hear
    from the ones here and in Orange County. Certainly, the Japanese
    White-eye audio samples sound nothing like the ones here. So why do
    birders identify them as Japanese White-eye instead of
    White-eye sp.
    
    Black Skimmers have been sticking around every day lately at the Cabrillo
    Youth Camp shore. They're very vocal whenever another skimmer comes in to
    land with them, and each one has an audibly different voice. I got to see
    a behavior I'd never seen before from this species a fish display. A
    skimmer held the fish in his bill, as if to entice the other skimmers,
    but none of them proved worthy of it (all who tried to take it were
    denied) and eventually he ended up eating it himself.
    
    On May 24 I had my first-of-season Least Tern at Cabrillo Beach dive and
    catch a fish in the water just outside the salt marsh.
    
    A Heermann's Gull adult in breeding plumage was at Cabrillo Beach today
    at 5:33pm. I haven't even seen an immature one since May 12, and hadn't
    seen an adult since March 24.
    
    I will post photos later.

  13. Continuing Brant, Pacific Loon, Willow Flycatcher & more (San Pedro) LINK
    DATE: May 28, 2018 @ 11:13pm, 4 month(s) ago
    Yesterday and today (May 27-28) both a Black Brant, and a Pacific Loon in
    absolutely full breeding plumage, were at Cabrillo Youth Camp (during the
    late afternoon, at least, when I looked on both days). The Brant spent
    time both on water and on shore. Both birds can be seen from the boat
    launch dock which is southeast-adjacent to the salt marsh (Salinas de San
    Pedro).
    
    On both May 23 and 25 a Willow Flycatcher showed up in my backyard,
    giving me a new yard bird. (It's possible they weren't even the same
    individual.) Other flycatchers have been especially abundant as well;
    Pacific-slope Flycatchers have been as numerous as I ever remember them
    being here, and Willow Flycatchers might be even more numerous than
    they've been before in my experience (i.e. since 2006). I saw an
    agonistic territorial encounter between two Willow Flycatchers for the
    first time (in my backyard) and one of them made an agonistic call
    sounding identical to a Say's Phoebe agonstic call (a call that many
    Northern Mockingbirds include in their song repertoire) a call which I
    think is most notable for its peculiar lack of
    "aggressive-soundingness" to human ears, in contrast to the
    agonistic calls of most other species. And I have found two Ash-throated
    Flycatchers recently at different local spots, one of them continuing,
    when Ash-throated Flycatchers have been mostly absent in my area for
    years.
    
    The Warbling Vireos are still present in force. I've had at least 6 at
    once in my backyard at times, and they often sing.
    
    I have observed proof of Orange-crowned Warbler nesting success in the
    Salt Marsh / Shoshonean Road area. An Orange-crowned Warbler, whose song
    I recognize from at least one year ago at the same location, fed a
    begging juvenile, and I recognized his identifying physical features from
    having filmed him singing earlier. And at another spot, an Orange-crowned
    Warbler sang for vast swaths of the day (also with a unique recognizable
    song), every day for weeks, and suddenly a few days ago stopped singing
    and started hanging out with a second Orange-crowned Warbler very
    suggestive that this pair are nesting as well.

  15. Claremont Black & Blue LINK
    DATE: May 14, 2018 @ 2:10pm, 4 month(s) ago
    This morning I birded CHWP/Claremont Hills Wilderness Park (a) looking for Willow Flycatchers (nope) and (b) hoping to get lucky, and see Black Swifts. It was overcast, cloudy, dreary, just flat-out depressing.
    No swallows and one White-throated Swift.Where you first enter the park, immediately to your right in the willows east of the fire road, there is a trail that nobody takes. It goes maybe 100 yards. No Willow Flycatchers, but I heard a Blue Grosbeak sing
    once, andgive its distinctive"Chink!" call note. Couldn't see it, despite standing there, motionless, scanning the willows where it washiding.
    Left, hiked the lower portion of Evey Canyon (no new species from last week e.g. Swainson's Thrushes, and less species than last week). Gave up, drove up to the Padua Theater parking lot,that looks down at
    Claremont Wilderness Park from the east. At this point the sun had come out, the clouds had dispersed, and it was warmer. Saw some small dark soaring things-with-wings off in the distance. Drove downhill, parked in the bend in Via Padova, got a somewhat better
    look at the motley collection of swifts and swallows far off to the west of me. Drove further downhill, hooked a right, then another right, with my low-rent, wrong-side-of-the-trackssquare CHWPsticker in my window,
    and parked in the Claremont Wilderness Park upper parking lot for beautiful thin people with the round CHWP parking stickers. Stood at the fence at the western edge of the parking lot, daring Parking Enforcement to write me up. A mixed flock of Violet-green
    Swallows, Cliff Swallows, White-throated Swifts, and two Black Swifts swarmed a few hundred yards to the west of me, over the radio antenna towers and buildings southwest of the park. Eventually, the whole flock came closer and closer, almost to the parking
    lot before saying, "Just kidding!" andturning around. I stayed for two more rounds of this form of aviary teasing, before putting the camera back into the car, and leaving at 1:30 p.m.
    I may, or may not go back tonight at 5:00, to see if I can get photos of them overhead i.e. above the Cobal Canyon Trail...or I might wait until the weather is consistently warm and dry for several days
    in a row.

  17. America's Birdiest County April 27, 28, and 29: More information LINK
    DATE: Apr 20, 2018 @ 5:34pm, 5 month(s) ago
    Hi Everyone,
    
    Here's additional information about the "America's Birdiest County" event that will happen in Los Angeles County on April 27-29, 2018.
    
    The count starts at midnight on Thursday night/Friday morning and ends at midnight on Sunday night/Monday morning.
    
    The objective is to find as many species in Los Angeles County over this three day interval as possible. We've been doing this since 2003 and regularly find more than 260 species.
    
    Birds can be identified by sight or sound, and as usual, rare species require documentation. All birds must be counted from land, so we can't accept anything seen on a whale watch, or from a boat on a lake, but we'd be glad to count any birds seen from Santa Catalina and San Clemente Islands or from seawatches at places such as Point Vicente and Point Dume.
    
    I will act as compiler again this year. Thank you again to Wanda Dameron for helping out as compiler in 2017.
    
    HISTORY
    
    America's Birdiest County started in 2003 in San Diego as a friendly competition among counties across the country to see how many species people could find in a single 24-hour period.
    
    After the first three years, the organizers changed the protocol to make it a three-day event. There were also various categories across the country to try to level the playing field so that counties in very different areas wouldn't be competing against those in other areas that have vastly more birds. Thus, counties in, say, Maine weren't competing against counties in California. Los Angeles was in the "Coastal West" category and our chief competition, at least initially, was with San Diego and Monterey. After the format changed to a three-day event, Monterey stopped competing in order to continue their traditional one-day county-wide birdathon. After 2011, the organizers discontinued the nationwide event, but selected counties continued due to strong local interest. Los Angeles and Kern Counties, which usually did very well, have both continued, and recently Orange and Ventura Counties have started similar events around the same time. In 2017 San Bernardino County started a count and had reported more than 230 species as of Sunday night.
    
    Here are the number of species found in Los Angeles County since 2003:
    Year Total
    2017 264
    2016 270
    2015 275
    2014 272
    2013 265
    2012 262
    2011 277
    2010 271
    2009 264
    2008 255
    2007 272
    2006 265
    2005 246
    2004 240
    2003 239
    
    Our total jumped in 2006 due to better organization and increased interest.
    
    This event has turned into an intensive sweep of the whole county each spring, and has provided a useful snapshot of the species that are present in late April. Many people who participate also record their observations in eBird, and as a result, tens of thousands of bird sightings are permanently archived, so in addition to having fun, we're also making a scientifically useful contribution.
    
    ######################################
    
    LOGISTICS
    
    Please email reports to me at lbenner@... and/or to the LA County listserve.
    
    We welcome forwarding eBird checklists--they make checking for new species really easy. The easiest way to do this is to email the eBird list to yourself and then forward it to me.
    
    I will provide updates two to four times each day to track our progress and to help guide searches for species we're missing. The first update will probably happen by mid afternoon on Friday. We will also provide updates each night so that we everyone can see what we still need first thing in the morning.
    
    Please note that we can't count birds seen from boats, but birds seen from Santa Catalina and San Clemente Island count. Also, the Gambel's quail and chukars on San Clemente Island are self-sustaining so we can count them. Also, to continue the protocol we adopted last year, we are now glad to count bald eagles seen from Santa Catalina and San Clemente Islands.
    
    ######################################
    
    NON-NATIVE SPECIES:
    
    Kimball Garrett asks us to please report established non-native species even if they're not the list that's accepted by the AOS (formerly known as the AOU) or the CBRC.
    
    This means that we want to hear about introduced species such as parakeets and parrots, pin-tailed whydahs, orange bishops, red-whiskered bulbuls, Mandarin ducks, and so forth. Monitoring those populations is becoming increasingly important so please report them, and, of course, enter your sightings into eBird.
    
    We'll keep them in a supplemental list separate from the "regular" species.
    
    ######################################
    
    RARE OR UNCOMMON SPECIES
    
    We've been keeping track of some notable species that have been in the area recently. Some are truly rare but others are regular winter visitors that become scarce and challenging to find in late April. Below is a partial list; we're sure there are some things that we missed. Please note that some of these species have not been found during previous ABC weekends, and for some birds it's been a few weeks since we've seen reports in eBird, on the listserve, or in various rare bird alerts.
    
    The list below includes species reported since about the middle of March, and we realize that some have probably left the area by now.

    SPECIES PREVIOUSLY RECORDED
    
    Below is the master list of every species we've found during previous ABC weekends.
    
    There are some species that we get regularly that are actually quite local and require special effort to find and/or that are just leaving or arriving at this time of year . Among them, in no particular order, are prairie falcon, American dipper, common ground-dove, Inca dove, spotted owl, northern saw-whet owl, northern pygmy owl, flammulated owl, burrowing owl, golden-crowned kinglet, Le Conte's thrasher, Williamson's sapsucker, red crossbill, Swainson's hawk, common merganser, hooded merganser, summer tanager, golden eagle, and wandering tattler.
    
    We often struggle to find pelagic species; alcids are particularly difficult.
    
    The table below lists every species we've recorded during the ABC weekend since 2004 and the number of years in which we've found it.
    
    N = number of years we've found a species from 2004-present.

  19. eBird and continuing wintering rarities, spring arrivals LINK
    DATE: Mar 21, 2018 @ 11:11am, 6 month(s) ago
    Birders,   As wintering birds depart, it is important to have good documentation of the length of stay of wintering rarities in the area (e.g. Pine Warblers, Dusky-capped Flycatchers, Eastern Phoebes, Rusty Blackbirds, etc.).  We are aware of too
    many cases where a rarity is listed in eBird with only the comment “continuing” after the bird had actually departed.  Therefore, we encourage observers to provide good documentation (photos, written descriptions) for each sighting of these birds from now
    until their departure.  We’d really like to know final dates as accurately as possible for these wintering birds, and since we can’t predict which date will be the “last,” we need documentation each time.   In a similar vein, arrival dates for spring migrants and summering birds should be documented as well.  Obviously many species have already arrived in good numbers (most swallows, Hooded and Bullock’s Orioles, Warbling Vireos, Western Kingbirds,
    etc.).  But we need good documentation for first arrivals from here on out – Black-chinned Hummingbirds, Willow Flycatchers, Olive-sided Flycatchers, Western Wood-Pewees, Flammulated Owls, Swainson’s Thrushes, Black-chinned Sparrows, Blue Grosbeaks, etc. 
    Please make the effort to enter as much documentation as possible in eBird with your fist spring sightings of these species, even if the sightings haven’t tripped the filters to require documentation.
    
    Thanks,   Kimball   Kimball L. Garrett Ornithology Collections Manager Natural History Museum of Los Angeles County 900 Exposition Blvd. Los Angeles, CA 90007 USA (213) 763-3368 kgarrett@... http://www.nhm.org/site/research-collections/ornithology

  21. eBird issues this Fall LINK
    DATE: Aug 24, 2017 @ 12:24pm, 1 year(s) ago
    Birders,   Fall migration is in full swing. The rate of use of eBird by Los Angeles County birders continues to skyrocket, with the obvious benefit of much denser information about our avifauna, but also with the drawbacks of continuing and even accelerating
    issues with data quality.  So here’s another in a series of occasional messages intended to improve the eBird database for our area.  If you know eBird users who are not on this list serve, always feel free to share these messages with them.  This mini-rant
    will cover three issues:  (1) Adding descriptions; (2) dealing with subspecies options; and (3) improving metadata in the “Comments” section.   DESCRIPTIONS This could be subtitled “There is a happy medium between Curtis Marantz and the average eBird user.”  We all know it is now easy (and desirable) to upload photos and audio files to one’s eBird checklist.  But when you are asked to document
    a flagged record, PLEASE keep in mind that such evidence is only part of the documentation that should support unusual records.  I am constantly amazed at how many eBirders will attach a photo (or 2 or 3…) to their checklist to document a rarity and will not
    write a single word about the sighting.  In many cases the photos are less than ideal, and might not even help support the identification; so we rely on the added value of a written description.  This is where Curtis comes in…..  you don’t have to write a
    Marantzian tome of 4000 words to document a rarity (though such detail is helpful).  But please add information about the circumstances of the sighting and any characters (e.g. size and structure, movements, other behaviors, plumage, voice, etc.) that are
    not evident from the photos as well as amplification of what is shown in the photos. And indicate how similar species were considered and eliminated.  I fear that the simple art of writing a good description of a bird to document a sighting and confirm its
    identification is disappearing from our birding culture. I largely blame the apparent need for instant gratification through smartphones and apps – why not jot notes down in the field (they have these things called pens, pencils and notebooks) and then add
    a thoughtful and detailed description based on these notes when you’re home sitting at your computer  Yes, it takes time.  But the alternative is having what might be a perfectly good record questioned or even invalidated by a reviewer. And as I have mentioned
    before (let’s call this section “Sandwiches I have Eaten While Birding”), concentrate on relevant points in your description and leave the irrelevant things out.    SUBSPECIES I strongly urge eBirders to enter data ONLY at the level of species, except in the few cases where well-marked subspecies are (usually) readily identifiable in the field; species with field-identifiable subspecies or subspecies groups in
    L. A. County include but are not limited to: Yellow-rumped Warbler, White-crowned Sparrow, Green-winged Teal, Red-tailed Hawk, Merlin, Northern Flicker (and intergrades), Bell’s Vireo, Hermit Thrush, White Wagtail, Red Crossbill (call types), Bell’s Sparrow,
    Savannah Sparrow, Fox Sparrow, and Dark-eyed Junco.  In some of these cases only one subspecies (or none) occurs regularly. In some other cases, observers with extensive experience and good studies of the bird in question can also reasonably determine subspecies
    (e.g. Orange-crowned Warbler, Marsh Wren, Song Sparrow, Canada Goose, Cackling Goose, Leach’s Storm-Petrel, Red-breasted Sapsucker).  There is nothing to be gained by indicating a subspecies based ONLY on your locality – so it’s preferable to enter “Osprey”
    rather than “Osprey (carolinensis)” even if you can be 99.9% certain that a local Osprey is of the North American carolinensis subspecies. An exception would be if you were able to study the bird well enough to rule out the other Osprey subspecies based on
    actual characters rather than locality.  A lot of the subspecies entry issues seem to arise from the use of smartphone apps, so when entering data via such an app be sure to select the full species rather than a particular subspecies (unless you can document
    the subspecies).  To the novice birder, some of the subspecies names might seem completely appropriate, even though they’re not.  A recent example is a birder who entered “Willow Flycatcher (Southwestern)” on the assumption that a Willow Flycatcher in the
    “southwest” should be that subspecies.  In fact, of course, the “Southwestern” Willow Flycatcher (Empidonax traillii extimus) is known from Los Angeles County in recent years only by a very few possible breeding pairs, with essentially no documented records
    of migrants.  So 99.9% of Willow Flycatchers in L. A. County will be what eBird calls “Willow Flycatcher (Northwestern) (Empidonax traillii brewsteri/adastus), even though Los Angeles County is hardly “northwestern.”  Why not just enter as “Willow Flycatcher”   METADATA AND INTRODUCTORY COMMENTS When you enter an eBird checklist you can make comments about that birding event in the Comments section on the second screen (“Date and Effort”).  It is unfortunate that eBird does not require users to enter information about conditions,
    but until they institute that capability, you can use the “Comments” section to add information on, for example, sky conditions, wind conditions, precipitation, temperature, tide, and other physical environmental conditions that can greatly impact your bird
    list.  Indicate how you covered the area (route, areas of concentration, etc.). Also a description of the habitat, any disturbances or other conditions that might impact your bird list, names of birding companions (these show up automatically only if the list
    is “shared” with them), condition of vegetation and food crop, and anything else that seems relevant.  Sure, you could even mention what kind of sandwich you had for lunch.   All of the above must seem like “work,” but I suspect a large number of you use eBird for the common good as a thorough avifaunal record rather than simply for an accounting of your sport-listing accomplishments.  Joseph Grinnell and other
    “early” naturalists in California might have spent hours writing in their journals about each of their field outings, and that information is invaluable to researchers today.  Can’t we, at least in some small part, try to do the same   Kimball   Kimball L.

  23. BT Gnatcatcher on Edwards AFB LINK
    DATE: Aug 12, 2017 @ 3:50pm, 1 year(s) ago
    LA Birders:
    
    This morning I found a female Black-tailed Gnatcatcher in the mesquite woodland of the south-central part of Edwards Air Force Base: roughly where 110th St East and Ave A would be. This is my second or third (a likely one got away from me last month) BT Gnatcatcher in this part of the Base this year.
    
    This bird was on the main base and is not accessible, but it must have moved here from somewhere: perhaps over or through someplace that is accessible. Keep your eyes and ears open for interesting gnatcatchers while birding the desert fringes of the AV. The bird today was quite vocal giving wren-like “chh-chh-chh” scolds repeatedly.
    
    Other things of local interest included a trickle of migrants: Cooper’s Hawk, Willow Flycatcher, Western Kingbird, Warbling Vireo, Bank Swallow, Blue-gray Gnatcatcher, and Yellow, MacGillvray’s, and Wilson’s Warblers.

  27. Piute Ponds: Pomarine Jaeger LINK
    DATE: Jun 26, 2017 @ 3:33pm, 1 year(s) ago
    Birders:
    
    This morning around 8:30 an adult Pomarine Jaeger flew south over the Piute Ponds and continued going southeast until I lost sight of it. It wasn’t chaseable and by now could well be at the Salton Sea, but definitely something neat and worth a mention.
    
    A late Willow Flycatcher by the entrance parking lot/toilet area, a Sora at the SE corner of the DU pond, and a Black-bellied Plover and some Western Sandpipers in Duckbill were the other birds of seasonal and local interest at the ponds this morning.
    
    See www.piuteponds.orgfor access and info.

  29. Sycamore Cyn. (no vireo, yes migrants) LINK
    DATE: May 18, 2017 @ 4:38pm, 1 year(s) ago
    Didn't hear the reported YT Vireo while surveying for CA Gnatcatcher/Cactus Wren at Sycamore Cyn. in Whittier this morning, but just passing along that there were lots of migrants in what has been a really slow (at least where I bird) May: double-digit Swainson's Thrushes, plus as many Wilson's Warblers as I've seen in the basin all spring, a couple Townsend's Warblers still moving, and Black-headed Grosbeak (the latter incl. breeders I'm sure).
    
    Had two Willow Flycatchers (both whit-ing) and a singing Olive-sided Flycatcher when I arrived. Displaying Yellow-breasted Chat c. 1.5 mi. up.
    
    The canyon is very, very birdy right now, with singing and family groups along the entire length.
    
    Sort of interesting, there are no July records of Yellow Warbler from the canyon, and just a single June record (4 on 6/13/09, L. Schmahl). I heard a probable one singing weakly about mid-canyon but obviously it could have been a migrant. They're thick at Whittier Narrows/SG River across the freeway all spring/summer.
