  1. Don't have any good photos. Found one excavating a cavity in an urban park just across the bridge in the East Bay a few years back. Cool behavior to see, poor photo.
  2. This bird has a clearly barred tail and a thin subterminal band, both of which are better features for calurus than they are for abieticola.
  3. I agree. R5 is the key here, and it doesn’t look particularly narrow. I’d lean heavily that this is an immature male RUHU.
  4. I completely agree. Juveniles are really…sharp (pun intended)!
  5. I know it's already been posted here, but gosh darn this bird is a subtle stunner! So fun to study up close. https://macaulaylibrary.org/asset/381144031 https://macaulaylibrary.org/asset/381144011

  7. Merlin? Wing shape looks wrong for an accipiter to me. Not sure it’s identifiable from these pics.
  8. Yeah, I guess it’s safe to call that narrow longest remige P10 on the near wing. It’s in heavy wing and tail molt and the opposite wing has either molted P10 or it’s relatively obscured. I agree with RTHU.
  9. Interesting bird. It's molting it's remiges and rectrices and thus confusing me. Per Howell, "Because of the P8-P10-P9 sequence of outer primary replacement, one could see a bird with P10 partially grown and a worn P9 retained, and mistakenly assume that P9 was the longest outer primary. This could affect judgement of “outer” primary shapes or relative wing/tail projectons on perched birds, and should be borne in mind. Also consider how tail moult (usually occurring when the outer primaries moult) could affect perception of wing/tail projections." If we had a really clean shot of the inner primaries, we may be able to ID the bird; but the longest outer primaries look vastly different due to molt. I'd safely call it Archilochus sp.
  10. These are LBDOs (or at least the lefthand bird is) due to the clean white lesser coverts on the underwing.
  11. The dorsal view of a COHA/SSHA tails is problematic at best. Wear, molt, and angle of viewing present significant ID challenges with regards to this field mark. The nape is suggestive of sharpie, although the lighting in the pic is not ideal. Structurally it feels much more like a coop to me. It’s head is not small and projects well beyond the wings in a manner which supports COHA. This bird is somewhat of a “tweener” IMO. I could see it being a juvenile female sharpie, but feel better calling it a juvenile male coop based on the above.
  12. MOBL. Structurally, the bird just looks looong.
  13. Birds #1 and #3 are Song Sparrows. Bird #2 is a Fox Sparrow. Notice the differences in the crown pattern and breast streaking, among other things.
  14. Both are very likely immature male Ruby-throats. However, since we can't see P10 or the shape of any of the rectrices (tail feathers), conservatively, I would safely call them Archilochus sp.
  15. This is correct. Tail is too long for Tennessee Warbler and facial patterning is not strong enough for TEWA. It's obviously not a Nashville so...Orange-crowned Warbler.
  16. There is significant white edgings to the secondaries, the amount of white in the cheeks is FAR too much for BOCH, and the cap looks too dark for BOCH. It’s a Black-capped Chickadee.
  17. Indeed. Strong facial pattern + pink legs/feet + white undertail coverts without any hint of buff = Blackpoll.
  18. For sure. Drab, streaky, pale supercilium, yellow untacs.
  19. Yes, bill length varies with regards to the sex the bird, and then there is individual variation within a species. Thus, only birds on the extreme ends of either spectrum can be identified with confidence…which also usually includes additional data (vocalizations, location, field marks on breeding birds and juvs., etc.).
