  1. no color on back or flanks = not Cassin's or Purple
  2. Realize that head and bill sizes vary between the sexes in both species, but... Lesser Greater
  3. Absolutely. It has a dark loral line, ruling out Pine Siskin.
  4. Distinct white wedge in outer primaries on underside of wing. There is only one choice.
  5. Sorry, meant to include this link, not the one that I wound up including, above. https://macaulaylibrary.org/asset/270543761#_ga=2.7942770.1755868588.1602438046-1184313056.1549327880
  6. Wing pattern, wing pattern, wing pattern -- both above and below
  7. https://ebird.org/media/catalog?beh=f&taxonCode=gadwal&mediaType=p&q=Gadwall - Mareca strepera
  8. Missed it. Common Tern -- among other features, Roseate has a thinner bill Massachusetts ROST and COTE
  9. Agreed; all I hear is a Killdeer, and the particular vocalization strongly suggests against a bird in migration.
  10. Shape and pattern are sufficient to ID most ducks. Gadwall is pretty distinctive in both.
  11. Heads too small and tails are too long and not notched enough for Purple Finch. And there is a migration component to House Finch occurrence patterns in the East.
  12. Extensively pale base to bill = Greater Bill by itself much longer than depth of head (front to back) = Greater Wing tips just barely longer than tail tip = Greater Short-primary projection = Greater Late October likelihood strongly favors Greater
  13. Note the very different patterns on head, back, and wings
  14. It has a bicolored bill, black maxilla, gray mandible. The wing pattern strongly suggests that it is an adult, which throws a weird monkey wrench into the ID. Perhaps it's a hybrid, with the mix of pink below and a more Black-headed-like bill. More pix would be useful.
