I agree this looks better for Nazca, especially with the added verbal description of bill color. The amount of white on in the central rectrices (for definitive basic feathers) appears substantial and

Thanks Adam - Based on this and other photos it is a first-spring bird by the narrow, brown, and pointed rectrices. I get the impression it's on the dull side for this species and so still think femal

There will be better photos than this but here are some crappy ones. High up in Eucs off NW corner. Seemed to head N when last seen by me and others around 11:45. <https://ebird.org/checklist/S7001698

The Lara's saw it at San Jose Avenue and Goeth Street, right on the SF-San Mateo border. It was first spotted by Max's son, Marc. Good skywatching! Peter

Just got a photo of a MIKI by Max Lara, taken at about 11:30 while looking for the ibis. Not sure where yet but near Lake Merced, I believe. Peter

Here’s another paper on the 1992 invasion. https://sora.unm.edu/sites/default/files/journals/auk/v113n04/p0911-p0923.pdf Interestingly, Patten et al. Linked it to anomalous El Nino conditions. I belie

Nice definitive alternate (breeding-plumaged adult) working area below N windmill to Irving. I posted some pics here: <https://ebird.org/checklist/S67244877>https://ebird.org/checklist/S67244877

Having had a chance to look at it more the plumage falls within range of variation for dark-morph juvenile Red-tailed and not Rough-legged, particularly in lacking a dark tail tip, having uniform unde

I’ll look at it again. I thought it hovered more like RLHA and the bill seemed small for RT. But it was a 5-second look, maybe too quick. P

Hi Mila - Looks like a dark-morph Rough-legged Hawk. Good bird for SF. Cheers, Peter

Details and photos <https://ebird.org/checklist/S63970929>https://ebird.org/checklist/S63970929 May be continuing? (It seems eBird alerts don't go out for "species pairs," even though this isn't one i

More specifically, the "Red-naped" Sapsucker (we'll have to check specimens to fully eliminate any Yellow-bellied Sapsucker genes, or at least try to) was present from about 1115 to noon in the large

Have confirmed with Jim Tietz that the Farallon Red-footed Booby was present out there yesterday morning at the same time as the one was being seen near the CG Pier.

Hi all - The good open-wing photos of the RFBO by Joe Morlan et al. <https://ebird.org/checklist/S61313179>https://ebird.org/checklist/S61313179 show that it is molting p5 whereas the SEFI bird <https

Late in day - it was present 6:45-7:00 pm.

Hi all - Just received a photo of a Rock Sandpiper taken at Heron's Head today by Terea Ely and Ben Dudek, via Siobhan Ruck. It was near the end of the point on the marsh side, sitting on a rock. Gues

This bird was found by Rudy Wallen two days ago. In overall plumage it seems in the overlap zone between an HY female Blue-headed Vireo and an adult male Cassin's Vireo - perhaps an HY male Cassin's c

Apologies for all the OROR posts... but my OROR2 below, upon further scrutiny of all the photos, does have a couple of black feathers in the throat (I had thought shadow), so maybe this is the one rep

After posting below I see the other reports of one with a black bib in the garden, which none of the ones I saw had. So, maybe "3-5". Peter
