This morning (12 May) around 0940 hr. I watched a very distant immature Masked/Nazca Booby -- it was observed from the platform on the outer point as I was scoping ESE (toward where Palos Verdes would have been if it weren't for the low clouds). At first
it was on the water, but it got up to join a small feeding flock of gulls, cormorant and loons around a group of common dolphins. I lost track of it soon thereafter.
The bird had a dark brown head and neck contrasting with a white upper back, a dark lower back, a white lower rump and upper tail coverts, a mostly dark tail with whitish in the central rectrices, dark wings with lots of white mottling on the upperwing coverts,
and white breast and belly. I couldn't tell anything about bill color from the distance of observations. I don't know of this is a second year bird or, perhaps more likely, a third-year bird. All of these details were discerned with the scope cranked up
There wasn't a great deal of activity off Pt. Dume otherwise -- 4 Sooty Shearwaters, 2 Pink-footed Shearwaters, a flock of 10 Brant, a flock of 4 Cattle Egrets, etc. At least 115 Bonaparte's Gulls were at the mouth of Zuma Creek.
In other news, there was a basic-plumaged Pacific Loon on the main lake at Hansen Dam around 0730 this morning.
