Yesterday April 26th I birded the upper slopes/summit area of Mt. Diablo (Oak Knoll and Blue Oak Campground, Green Ranch Rd., Muir Picnic Area, Juniper Picnic Area, the summit, and some of summit

Thanks for the report, Jim. Yesterday (Tuesday) I had my first tanager and Hermit Warbler at the Gyuto temple, and just this morning I had at least 7 tanagers high up in the Eucalyptus in Alvarado

I thought the documentation was spot on and the tail flicking description precise.  As Cornell notes - Dusky Flycatchers are best distinguished from Gray Flycatchers by behavior. They do not wag

San Benito Mountain? Yes, that must be what Stokes and Sibley have outlined as summer presence of the gray flycatcher. It's south of the "Bay Area" isn't it? So, yes, that must be what I was referring

Tail flicking is a rather confusing term. I took pains to describe it in a previous post, but briefly from my observations of gray flycatchers where dusky and Hammond's are also present, the gray

Incredible day of birding. I had heard from a neighbor that the Red-whiskered Bulbul continues in Fruitvale, on Blossom St. and Davis St. the next street east. Found it at 9am. then went to work at

I also saw a Western Kingbird around 11:00 AM today near the top of Vollmer Peak in Tilden in the brush below. Probably not the same bird, but they are around. Ed -- Edward Vine Lawrence Berkeley

Hi David, Where did you find the information about isolated breeding populations of Gray Flycatcher anywhere in the Bay Area? Based on everything I’ve ever read , their breeding range in California

Kevin, Western is the usual kigbird suspect in summer around here for grasslands and meadows like Cesar Chavez. Tropical Kingbirds do show up here fairly regularly. Western Kingbird has white outer

Pretty the kingbird I spotted at Cesar Chavez Park this morning was a Western Kingbird. I've only ever confirmed a Tropical Kingbird. Any advice welcome. Check out my notes and phots in the ebird

Best day for migrants this year so far. 5 warbler species and lots of Hermit warblers by 7:15am. (Below Vollmer peak Tilden) Jim Chiropolos Orinda

One of these was probably seen SUNDAY at 3:00 PM at the Hayward Regional Shoreline. It was at Winton Ave. It was only seen in flight. For details see my ebird report under pigeon/dove sp. My view was

At about 5:30 tonight I saw a FRGU at low tide in the bay just off the SF Bay Trail between Meeker Slough and 51st St bridge, north of Pt Isabel. A small gull among CAGUs with a black head, thick

On a cheerier note I heard a FOS Olive-sided flycatcher and a Swainson's thrush singing quietly this morning on The Strawberry Canyon trial, Berkeley. Other migrants heard were a Cassin's vireo and
