  3. Slaty-backed Gull photos LINK
    DATE: Jan 6, 2018 @ 6:41pm, 12 day(s) ago
    Hi all,
    
    I've posted some photos of the Slaty-backed Gull in this eBird checklist:
    
    http://ebird.org/ebird/view/checklist/S41692655
    
    The bird flew north at around 3pm; I didn't see it later in the gull flock in the north pond.
    
    I welcome insight on the bird's age; I'd thought it was a retarded second-cycle last year, but I'm having doubts. As with last year's bird, it stands out in the flock as being very large.

    Birders,
    
    6 January 2018
    
    What appears to be the same Slaty-backed Gull as last winter has returned to the San Gabriel River Coastal Basin Spreading Grounds in Pico Rivera. The bird is currently (2:30pm) in the gull flock at the north end of the south basin, near Mines Ave. I'll post photos on eBird this evening.
    
    Earlier, a male Eurasian Wigeon was on the LA River just below Alondra Blvd.

    This is the Los Angeles Rare Bird Alert for February 24.
    
    A TUNDRA SWAN was at Pierce College in Woodland Hills from February 19-23. It has been in the fields south of El Rancho Drive.
    
    A female EURASIAN WIGEON is being seen at Oxford Basin in Marina del Rey. It was reported there though February 21. Low tide appears to be the best time to look for it.
     A “EURASIAN” GREEN-WINGED TEAL continues along the LA River adjacent to the Bette Davis Picnic Area in Glendale. It was reported through February 20.
    
    A first cycle ICELAND GULL was found at the Rio Hondo spreading basins at the west end of Mines Ave. on February 18. Two LESSER BLACK-BACKED GULLS (both an adult and an immature have been present)
    continued off and on at the basins through February 20. The also irregular YELLOW-FOOTED GULL was seen again on February 20.
     The gulls have mostly been in the basin below Washington Blvd. Afternoons are best and Sundays should be avoided (as the nearby landfill that attracts gulls is not operating). To reach the
    basin south of Washington Blvd., take Paramount to Canford and turn west. There is access here through a
    
    hole in the fence.
    
    A second cycle SLATY-BACKED GULL at the Rio Hondo spreading basins was last seen there on February 11. More recently it was spotted at Junipero Beach in Long Beach (near Shoreline Drive) on
    February 19.
    
    A HAMMOND’S FLYCATCHER continued at Valley Plaza Park in North Hollywood through February 21.
    
    A GRAY FLYCATCHER was at Valhalla Memorial Park in North Hollywood on February 21.
    
    The EASTERN PHOEBE at Madrona Marsh in Torrance was reported through February 23 in the southern part of the preserve near the Chevron (gas station) corner. Preserve hours are 10AM-5PM Tuesday
    through Sunday.
    
    Up to five VERMILION FLYCATCHERS have seen at Oakdale Memorial Park in Glendora through February 20.
    
    The continuing DUSKY-CAPPED FLYCATCHER at Creek Park in La Mirada was reported in and near the eucalyptus grove south of Las Flores Ave and north of Imperial Highway through February 20.
    
    The TROPICAL KINGBIRD at the Earvin Magic Johnson Recreation Area in Willowbrook continued through February 20. The island in the south lake is a good spot to check, as well as adjacent areas.
    
    After going unreported for some time, the wintering THICK-BILLED KINGBIRD at Horsethief Canyon Park in San Dimas was seen again on February 19 and also through February 21. It tends to favor
    the wooded ravine just west of the dog park, but can move widely around the area. The entrance road may be gated after storms, but the road can be walked, with parking available near the San Dimas Nature Center.
     A BLACK-AND-WHITE WARBLER was at La Mirada Community Regional Park on February 20. It was inside the Splash! property.
    
    The PAINTED REDSTART at The Estates Condominiums in Rolling Hills Estates was reported through February 21 around building 3604.
    
    A CLAY-COLORED SPARROW continued at the Rose Garden in Exposition Park in Los Angeles through February 18.
    A SWAMP SPARROW continued along the Playa Vista Riparian Corridor below Loyola Marymount University through February 23. It is being seen near the hillside concrete drainage channel adjacent to the end of Village
    Drive.
    
    A WHITE-THROATED SPARROW continued through February 23 at the LA County Arboretum in Arcadia on the northeast slope of Tallac Knoll in the southwest corner of the property.
    
    
    A HARRIS’S SPARROW was found along Thompson Creek Trail in Claremont on February 22 (but reportedly present before then). It was seen again on February 23. To reach the exact location,
    drive to the very north end of Indian Hill Blvd. in Claremont. There is a free parking lot to the left. Walk east about one half mile along the Thompson Creek Trail by the water channel. The first feeding
    station can be seen on the right by a bench and drinking fountain. There are bird feeders and a solar panel water dish on the ground. Walk about one more block to Pomello Ave. (closed to parking) where there is a locked large metal yellow gate to your left.
    Slip past it at the channel, and just to the right is the second feeding station which the Harris's seems to prefer.
    
    A SUMMER TANAGER was at a residence in the La Canada area in February 18.
    
    A BLACK-HEADED GROSBEAK was at a feeder in Trancas Canyon on February 17.
    
    The female ORCHARD ORIOLE at the LA County Arboretum in Arcadia continued through February 21. It has been in the Aloe Garden (just northwest of the entrance complex). It especially favors
    the Kei Apple Trees, but if missed there check other flowering plants in the vicinity.
    
    A male SCOTT’S ORIOLE was at Bonelli Regional Park in San Dimas on February 20 and 21. It was seen from Group Picnic Area 4.

  9. Yellow-footed Gull at Rio Hondo Spreading Grounds LINK
    DATE: Feb 20, 2017 @ 5:32pm, 11 month(s) ago
    Birders,
    
    A group of us watching gulls at the south pond of the Rio Hondo Spreading Grounds in Pico Rivera this afternoon (20 February) struck out on Iceland, Lesser-black-backed and Slaty-backed gulls, but it was at least encouraging that there were >1000 gulls (at
    peak count). Eventually Matt Grube, along with Roger and Michael Woodruff, picked out the presumably continuing Yellow-footed Gull on the west bank of the pond, and we were able to keep track of it until Jon Dunn arrived, at which point it promptly flew (after
    showing Jon its legs), circled, and landed on the water with lots of Western and California gulls. We were able to relocate it on the water because of the large, thick bill (slightly exceeding bill depth of even the largest male Westerns), but of course leg
    color (deep yellow throughout, including webs) was not helpful on the swimming bird.
    
    It's obvious that turnover is huge at this location, hour to hour and day to day, but it's worth studying the gulls here any day except Sunday.
    
    Again, the best viewing is reached by taking Paramount south from Washington, turning right (west) on Canford, and parking at the end -- convenient gaps in the fence here attest to the shared needs of birders and the homeless.

  11. Whereabouts of the Slaty-backed Gull LINK
    DATE: Feb 20, 2017 @ 4:58pm, 11 month(s) ago
    Hi all.
    
    Yesterday (Sunday, 19 February) I found what appears to be the same Slaty-backed Gull previously reported from Pico Rivera, at Junipero Beach in Long Beach. The gull was in a huge flock of mostly California Gulls near the western end of the beach close to Shoreline Dr. It was standing in a large puddle of water which offered some protection from the constant stream of children flushing other parts of the gull flock. It allowed relatively close approach without showing too much concern. 
    
    Photos are in my eBird report:  http://ebird.org/ebird/view/checklist/S34593384
    
    Apologies for the lateness of this report. I am traveling and did not have time to deal with this sighting.
    
    Take care,

  15. New Slaty-backed Gull location? LINK
    DATE: Feb 20, 2017 @ 10:52am, 11 month(s) ago
    I've asked Bernardo Alps to post more details, but he sent me photos of "the" Slaty-backed Gull taken yesterday (19 February) on the beach in Long Beach at Junipero Ave. This might be a good alternate area to look for the bird when it is not up at the spreading
    basins in Pico Rivera (especially on Sundays, it seems, when the landfills are not operating and there are very few gulls in the spreading basins).

    This is the Los Angeles Rare Bird Alert for February 17.
    
    The “EURASIAN” GREEN-WINGED TEAL continues in Pico Rivera and was reported through February 12 (be aware that an intergrade Eurasian/American Green-winged Teal has also been seen here recently).
    It has most recently been on the island in the south basin. The basins are between Whittier and Washington Blvd. and west of the 605 Freeway. Access is from the east end of Mines Ave. or at the southwest corner of the basins via Pico Vista Road.
     A second cycle SLATY-BACKED GULL was seen in Pico Rivera off and on through February 11. It has been both at the San Gabriel Coastal Basin Spreading Grounds and more recently at the Rio Hondo
    spreading basins at the west end of Mines Ave. One to two LESSER BLACK-BACKED GULLS (both adult and immature birds have been seen) also continued at the Rio Hondo spreading grounds through February 15. There is access at the intersection of Mines and Paramount.
    Gulls here have been at several of the basins here depending on water levels. To reach the basin south of Washington Blvd., the simplest way (other than taking the long walk from the Mines entrance) is to take Paramount to Canford and turn west. There is
    access here through a
    hole in the fence.
    
    A SHORT-EARED OWL was in the west Antelope Valley on February 11 near 300 th Street West and the LA Aqueduct.
    
    A NORTHERN “YELLOW-SHAFTED” FLICKER was in the southwest part of Inglewood Park Cemetery on February 10.
    
    A HAMMOND’S FLYCATCHER continues at Valley Plaza Park in North Hollywood. It was in the northeast area through February 11. Another HAMMOND’S FLYCATCHER was at the South Coast Botanic Garden
    on February 12.
    
    A PACIFIC-SLOPE FLYCATCHER continues at the West San Gabriel River Parkway Nature Trail, being last seen on February 12. It has been at the south end of Monte Verde Park (fenced, but adjacent
    to the north end of the nature trail.
    
    The EASTERN PHOEBE at Madrona Marsh in Torrance was reported through February 15 in the southern part of the preserve near the Chevron (gas station) corner. An ASH-THROATED FLYCATCHER also
    continues at Madrona, being last seen on February 13. The WESTERN KINGBIRD at Madrona Marsh in Torrance continued through February 12. Preserve hours are 10AM-5PM Tuesday through Sunday.
    
    The EASTERN PHOEBE at Bonelli Regional Park in San Dimas continued through February 12 on the north side of the park around Group Picnic Area #4.
     VERMILION FLYCATCHERS continue, with four at Castaic Sports Complex seen through February 11 and one at the Earvin Magic Johnson Recreation Area in Willowbrook (usually on the island in the
    south lake or in that general area) through February 13.
    
    The DUSKY-CAPPED FLYCATCHER at Creek Park in La Mirada was heard in and near the eucalyptus grove by Imperial Highway again on February 11.
    
    The TROPICAL KINGBIRD at the Earvin Magic Johnson Recreation Area in Willowbrook continued through February 11. The island in the south lake is a good spot to check, as well as adjacent areas.
    
    A BLACK-AND-WHITE WARBLER was on Tallac Knoll at the LA County Arboretum from February 11-14. A WHITE-THROATED SPARROW continues here as well at the top east side of the knoll.
    
    The YELLOW-THROATED WARBLER at the Earvin Magic Johnson Recreation Area in Willowbrook continued through February 13. It has most often been around picnic table 12 and around the area northwest
    of the south lake.
    
    The PAINTED REDSTART at The Estates Condominiums in Rolling Hills Estates was reported through February 12 around building 3604.
     Another PAINTED RESTART continues at the Venice-Barry Apartments in Mar Vista. It was reported on February 12 just north of the apartments on the west side.
    
    The GREEN-TAILED TOWHEE at the West San Gabriel River Parkway Nature Trail continued through February 10. Another was at the South Coast Botanic Garden on February 12.
    A SWAMP SPARROW continued along the Playa Vista Riparian Corridor below Loyola Marymount University through February 12. It is being seen at the hillside concrete drainage channel adjacent to the end of Village
    Drive.
    
    A WHITE-THROATED SPARROW was north of the entrance at Cobb Estate in Altadena on February 10. Others were at Neff Park in La Mirada on February 10 and at the South Coast Botanic Garden on February
    12.
    
    A DARK-EYED “PINK-SIDED” JUNCO was at Linden H. Chandler Park in Rolling Hills Estates on February 14.
    
    A male SUMMER TANGER continues at the Bette Davis Picnic Area in Glendale. It was seen through February 12 on the east side of Riverside Drive, and is often in the area around the small wooden
    sheds.
    
    Another SUMMER TANAGER was in Pasadena near the intersection of Arden Road and Lake Ave. on February 15.
    
    The female ORCHARD ORIOLE at the LA County Arboretum in Arcadia continued through February 12. It has been in the Aloe Garden (just northwest of the entrance complex).

  19. Adult Lesser Black-backed Gull, Rio Hondo Spreading Grounds LINK
    DATE: Feb 15, 2017 @ 9:48pm, 11 month(s) ago
    Among the many hundreds of gulls on the large pond south of Washington Blvd around 3pm today was a fine adult Lesser Black-backed Gull. Despite my best efforts, in 3 hours of searching, I wasn't able to pull out the potential Slaty-backed Gull. But with so many gulls, it was a daunting solo effort.

  23. Slaty-backed Gull - Rio Hondo Spreading Grounds LINK
    DATE: Feb 7, 2017 @ 8:11pm, 12 month(s) ago
    Hi All,
    
    The putative Slaty-backed Gull found by John Garrett was on the Rio Hondo Spreading Grounds today. David Bell, Catherine Hamilton and I found it at about 1:00pm, but it was only on the water for about 15 minutes before it peeled off east. The Rio Hondo Spreading Grounds were loaded with gulls today with the San Gabriel Spreading Grounds almost completely gull-less.
    
    A couple of pics are on my Flickr account:https://www.flickr.com/photos/127901929@N04/32393776090/in/photostream/

  25. Slaty-backed briefly returned LINK
    DATE: Feb 4, 2017 @ 1:43pm, 12 month(s) ago
    Hi,
    
    A group of us here at the San Gabriel Spreading Grounds just had the Slaty-backed Gull in the south pond (2/4). It stuck around for only a few minutes, unfortunately, before circling for a long while and eventually going west (perhaps toward the Río Hondo Spreading Grounds). Photos on eBird later.

    A WESTERN KINGBIRD was at Madrona Marsh in Torrance on January 27.
    
    A BLACK-AND-WHITE WARBLER continued at Legg Lake in South El Monte through January 27 in the area west of restroom 7. This spot is west of the Santa Anita parking area (just south of the 60
    Freeway). Also at Legg Lake was a continuing WHITE-THROATED SPARROW seen along the south fence line on January 27.
    
    Another BLACK-AND-WHITE WARBLER continued east of the library at Ed Segundo Library Park through January 28.
    
    A new BLACK-AND-WHITE WARBLER was in trees at the west end of the gully at Peck Park in San Pedro on February 1.

  29. Re: [LACoBirds] Apparent Slaty-backed Gull, San Gabriel Spreading Grounds LINK
    DATE: Feb 1, 2017 @ 7:11pm, 12 month(s) ago
    I spent a couple hours (1-3 pm) this afternoon (Feb 1) along with a few others looking for the apparent Slaty-backed Gull found yesterday. To my knowledge it was not seen today, however, we did come across a gull that was superficially similar to this gull, but that I believe is a second cycle Herring Gull. I have posted some photos on my Flickr page if anyone is interested. The only other gull of note this afternoon was an adult Lesser Black-backed Gull.
    
    My understanding is that there were lots of gulls south of Mines Avenue prior to noon, but they all flew off, with large numbers of gulls seen at the Rio Hondo spreading grounds shortly thereafter. Several hundred gulls did eventually return to the pond south of Mines Avenue, but many fewer than were present earlier in the day. When I left at 3 pm, only about a hundred gull remained.
