  1. Hear, hear Bald -- head and tail projections roughly similar Golden -- head projection about half that of tail projection
  2. And I assume that you meant "Rough-legged," as Northern Rough-winged Swallow is long gone for winter.
  3. Dark morph (rufous is intermediate morph and has a black belly band contrasting with rufous chest and vent area)
  4. Both Cassin's and Purple finch adult males have the flank streaking within the reddish color below; House Finch does not.
  5. At least two Cacklings in the photo, with a possible third facing mostly away from the camera and right behind (but closer) than the photo's subject goose.
  6. Americans usually have pink legs and feet at this time of year. https://cobirds.org/CFO/ColoradoBirds/InTheScope/59.pdf
  7. Not female-type, it is a female House Sparrow. Males look like females only in the nest and shortly after fledging. They quickly attain male plumage. House Sparrow is not a member of the New World family of sparrows (Passerellidae), but of the Old World family that was originally called sparrows (Passeridae).
  8. However, why not Greater Yellowlegs, which is commoner late in fall than is Lesser and sports a somewhat contrastingly pale bill base, as the photo seems to show?
  9. Yes, Harris's is ruled out by the long wings (extending to tail tip), as that species, being essentially non-migratory, has relatively short wings. Additionally, the tail's color pattern is reversed fro that of Harris's. However, this could be a dark morph of either Red-tailed or Ferruginous hawks, and that's as precise as I can be, given the photos.
  10. Probably as akiley suggested, though size in geese has been shown to be correlated with food supplies on breeding grounds during breeding season -- more/better food = larger; less/worse food = smaller
  11. Adult male Common Mergansers https://cobirds.org/CFO/ColoradoBirds/InTheScope/82.pdf
  12. immature male Lesser Scaup https://cobirds.org/CFO/ColoradoBirds/InTheScope/21.pdf http://cowyebird.blogspot.com/2018/02/greater-scaup-ebird-problem-child.html
  13. I would also say that overall coloration of females of the two big grackles is quite variable and I wouldn't count on that feature to differentiate among the two species (see GTGR here). In Texas, Boat-tailed is virtually restricted to tidal areas in east TX; Great-taileds can be found most everywhere.
