The Contra Costa County Health Department announced that the Shelter In Place order has been extended through May 3. Mt. Diablo Audubon Society has cancelled all remaining field trips through that

Friends! A few years ago, Dave B., one of the scholarly First Friday birders, decided that “selasphorus” was Latin for “either one or the other”! Best of Boids! Alan Kaplan

Of interest to everyone: Sibley says the "general shape and pattern of dives is distinctive", then shows Rufous performing repeated steep dives while Allen's "often" begins with back and forth shuttle

Does anyone know of links to recordings that show a difference in the sounds of Allen's vs. Rufous Hummingbirds? Sibley suggests there's a difference: Allen's "Male dive display produces high, humming

In El Sobrante, I have both gold and white crown sparrows yet. However, there are fewer gold crowns and more white crowns than 2 weeks ago. The gold crown have been singing for about a week -so I

Unless I can positively identify as Rufus I've started counting as Allen's\Rufus. It is difficult at best to get a good look at the tail feathers in the field and from what I have recently read the

Here in Martinez, I currently have 8 white crowned sparrows, the gold-crowned left a few days ago. Also, 4 days ago a Hermit Thrush was skulking around my bushes in the early evening, heading to

Yesterday while sitting near the window, I noticed a Chickadee looking inside the bird house in our patio. It has been several years since they nested there, so we have great hopes. And thank you,

Comments on what the CCCO Breeding Bird Atlas says would be appreciated.

In the past few days I've had two unprecedented sightings for March in my yard. I get these birds every October, but never, in 20 years of observations in March. My home is in northeast Lafayette,

Hi All, Just to add a bit more of what I've noticed in Contra Costa County specifically the past few years, rather holistic and not scientific... Allen's Hummingbirds generally are expected breeders

Yes, Allen's breed between the Bay up into the East Bay hills. They also breed at Coyote Hills and I think there may be recent nesting records in the Diablo Range which doesn't get much fog. Allen's

While spending time at home at the mouth of Niles Canyon, two days ago I had an adult male Black-headed Grosbeak check out a hummingbird feeder, and today I heard a Pacific-slope Flycatcher. For some

Yesterday afternoon I hiked out along Briones Reservoir from the Bear Creek staging area, counterclockwise. In a narrow inlet, I spotted a pair of Wood Ducks and there may have been more (flybys

Sent from Xfinity Connect App Hi Joe, I am in Castro Valley, quite far from the fog and I am 100% certain that the hummers at my feeder are Allen’s. No doubt about it. Mike Shannon

I believe Rufous is more likely than Allen's in Pleasant Hill. Allen's prefers coastal fog. That said, the females are not distinguishable in the field unless you can see the shape of the tail

Twice in the last few days I’ve seen an adult Bewick’s Wren pick up a seed from a crack in our deck and give it to a nearby adult Bewick’s Wren. It’s too early for a fledgling to look adult,

Hi folks- we had what I think might be an Allen's hummingbird at one of our feeders in southern Pleasant Hill. It was a female.Here's the ebird list with photos.

Two White Pelicans together at Lake Merritt this afternoon - and another swimming the other side of the islands. Unusual for March, based on the GGAS 4th-Wednesday walk records. Also - finally! - one
