  1. This is especially true with Mountain Bluebirds, which these are.
  2. Rose-breasted can have a darker upper mandible, and Black-headed can have a paler upper mandible. So basically, both Rose-breasted and Black-headed Grosbeaks can have bills with a little black on the upper mandible. Rose-breasted generally has more streaking than Black-headed, although this is variable, and both Rose-breasted and Black-headed can be very streaked, or not streaked at all (Although most Rose-breasted have at least some streaking). Rose-breasted is generally a lot cleaner than Black-headed, although this is also variable. This bird's bill is very pink, which points to Rose-breasted, but given how wet and worn this bird is, I wouldn't call it. Best left as a / imo.
  3. Common Chiffchaff is a very rare but probably regular spring and fall migrant to western AK.
  4. The front bird (the bird that stays still in both pics) in the first photos is a Least. The back bird is indeed SESA.
  5. Leaning towards female Mallard based on strong primary "windows" and brown neck, and stronger two-tone underwing. It does have a very "Gadwally" feel to it though.
  6. Oh, woops! For some reason I momentarily thought you were based in LA County. ?
  7. Naumann's Thrush was formerly lumped with Dusky Thrush and was (finally) recognized as a separate species by American authorities a few years ago. There have been several records of Dusky/Naumann's Thrushes reported in AK in recent decades, as well as many reports of hybrids between the two taxa in AK. They certainly have had a good fall in the western Aleutians this year, with highlights being the ABA's first record of Icterine Warbler, 3rd Red-backed Shrike, 8th Yellow-breasted Bunting, Tree Pipit, Middendorf’s Grasshopper Warbler, and Taiga Flycatcher.
  8. Yeah, but your county waters are deep in murrelet-and-Boobybreeding-land and ours aren't! ?
  9. We had one a weekish ago, and the only terns we had besides Royal and Elegant were a Forster's and a Black Tern, which we missed.
  10. We didn't see any Sterna on our pelagic either, although our county waters are a birdless desert compared to almost all other coastal county waters in CA.
  11. Same things as @Aidan B mentioned above, plus limited buffy bases to outer primaries are typical of fresh HY LESPs before 1st preformative molt. Also, I probably wouldn't call the 1st bird from that pic.
  12. Nice catch. 3 is indeed a Least, and now I'm not sure on the first bird...
  13. Overall thick-based wings, wedge-shaped tail (Often folded, as in this bird), and especially small size compared to nearby Black SP. For future reference, flight style and molt sequence (although the latter is not as important in North American species) is a good way to identify Storm-Petrels. Here is an article I've found helpful: http://www.oregonpelagictours.com/2015/11/west-coast-storm-petrel-flight-style.html
  14. Looks okay for Least based off of the 2nd pic.
  15. Dark cap extending around nape, somewhat of a murky dark-and-reddish bill in this plumage, and dark primaries. I am not sure, it looks like the bottommost bird could Common, but I would expect to see darker primaries on that bird. The top bird could be Common as well, but I wouldn't call it without seeing shots of the head. I wouldn't call the remaining two from that shot.
