  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.
  14. https://cobirds.org/CFO/ColoradoBirds/InTheScope/82.pdf
  15. Immature male Lesser Scaup; Any Blue-winged Teal with blatantly obvious white between eye and bill would look nothing like this. Note that, with few exceptions, diving ducks have relatively unpatterned feathers, while dabbling ducks have patterned feathers (that is, with multiple internal markings; and that doesn't count the dark bars on male scaup feathers, as on this bird).
  16. It actually depends upon where you are. Lesser Scaup are quite common saltwater in winter in the southern US.
  17. It sounds familiar, but it doesn't sound to me like Yellow Warbler.
  18. Bill color in female Northern Shovelers, though variable, is typically dominated by orange: https://ebird.org/media/catalog?taxonCode=norsho&mediaType=p&sex=f&q=Northern Shoveler - Spatula clypeata Also note the caveats about sexing Northern Shovelers here. However, the gray tertials contrasting paler with the rest of the upperparts coloration is a Mallard feature, but not a Northern Shoveler feature. The bill pattern is certainly uber typical of female Mallard.
  19. Congrats on the Iceland Gull, finally (middle bird) -- all-dark bill, whitish primaries. Otherwise, Herrings (adult and first-cycle -- note distinctive bill pattern with dark of tip running in toward base along cutting edges).
  20. I think that there is just not enough information in the single photo to provide for a definitive ID. The apparent pointed primaries ages it as a first-cycle beastie, but that's as far as I feel that I can go with it.
  21. I don't know that I'd go that far. I would say that Great-tailed has not been reliably reported from Florida; I have little doubt that it has occurred. Note the nearby record from Alabama: https://ebird.org/map/grtgra?neg=true&env.minX=&env.minY=&env.maxX=&env.maxY=&zh=false&gp=false&ev=Z&mr=1-12&bmo=1&emo=12&yr=all&byr=1900&eyr=2020 Except for the immediate vicinity of Pensacola, western panhandle Florida (where GTGR is probably most likely) is lightly and poorly birded. It's also mostly wonderful, very different from peninsular Florida, with oodles of native habitat, even Black Bears.
  22. Red behind eyes is also a feature frequent on Red-naped and not something that I've seen on Yellow-bellied.
