I saw the parakeet auklet from the shipwreck lookout today. Sometime between around 11:30 to 12:30. Initially observed in the surf to the west of hermit rock. Visible there about 10 minutes. Observed

This is a fun and easy video about using some spectrographs to ID birds: https://www.instagram.com/tv/B_0HLv5A6Lr/?igshid=e2fyi48vcnhu

Thanks Lee (and Lee!). I’ll go look later this afternoon. Did you mean Hooded Oriole family? I’m not aware of any breeding efforts by Hooded Warblers in California this year. Thanks, Aaron

Hi, Today (June 25), following a tip from Lee Guichan that she saw a possible male Lawrence's Goldfinch near Julius Kahn Playground on June 16, I believed I have found the male LAGO after a week's

All, I sent the unidentified recordings to a friend, Don Kroodsma, a long time bird song researcher without revealing anything more than the recording was made in the SF area. He researched Bewick's

All I thought I would write a bit about sound analysis, for those interested in that aspect of the conversation. Having grown up listening to Eastern warblers, that bird just did not sound

Hi Brian You have brought up a most important point, that the actual details of this "sighting" (problematically in this case a "hearing") remain incomplete. Maddeningly so. As for the analysis of

Not to distract from the bird in question (and I think we all deserve a conclusion to this thread with a visual ID;), but it is my understanding that sonograms have been in wide use in bird

This is striking a deeper issue for me, so I'll try again. If this is a Bewick's Wren, then it's not likely a migrant, and it could be out there trilling away in McLaren, if only we knew where to

This should be better. Sialia doesn't show attachments. If it's still tiny, just look at someone else's post for the Spectogram. From Denise Wight: Hi Daniel, I'm going with Bewick's Wren. In the

Hi all, Just thought I should add my checklist with the spectrogram for those who haven't seen one (thank you Frank F. for including those). https://ebird.org/checklist/S70759209 Eddie

Hi again, Vocalizing a while now in large oak and bay (guess!) trees 100 yds south of large redwood in Bunny Meadow in Golden Gate Park. In other words in the woods. Same longitude as Lily Pond. West

Denise’s take attached (hopefully):

Just need to add that bewicks wrens singing high up in trees is not unusual. John Sterling 530 908-3836 26 Palm Ave Woodland, CA 95695

Brian Make a spectrogram of that song, and then compare it to Blue-wings. It is quite different in its frequency range and average frequency. This is in addition to the overall structure of the

As Alvaro mentioned, the pitch of the trill is too low for Blue-winged (and spot-on for Bewick's Wren). Attached is a sonogram of the mystery call, as well as a BWWA and BEWR. The highest energy

I received a partial reply from Eddie to the effect that the bird was heard singing both late morning and again late afternoon, both times at mid to upper levels of the trees. Neither Spotted Towhees

All, I think Bewick's Wren is the right answer for this one. I've had a Bewick's Wren singing this dialect in my back yard (Sunnyvale) for a couple years now. When it first arrived, it had me hoping

Redstart singing and seen often from 10:45 to present on lake side of the path near the placard for the children's story book project that starts: "Wind found the note and tossed it into the sky."

Hi Eddie, Thanks for reporting the mystery bird. Could you possibly give some details for those of us who feel that this is a mega rarity? What time of day did you hear it, how long did it sing
