  1. What is "M.I.?" I suspect it is a geographical cognomen, but I don't recognize it.
  2. Read the length data in your field guide - Dunlin is not obviously smaller than Sanderling. For inter-specifcally flocking birds, size comparison is incredibly useful.
  3. The bird in the original pic is a first-year male Scarlet -- note the contrast of replaced black wing coverts, but brown flight feathers. The bird in the second photo is an adult -- note the all-black wing.
  4. Male American Kestrel -- the wings are blue above and the base of the tail has no banding.
  5. The fact that the vent area is shown well rules out Black-throated Green, as that species sports a greeny-yellow vent strap.
  6. "Western" is a subspecies -- calurus That's not atypical for juv, dark-morph Western Red-taileds.
  7. Tennessee does not exhibit chest streaking, particularly in Florida.
  8. Regarding the duck, see here. I say that the warbler nicely fits in the "warbler sp." entry, though I think that Nashville is ruled out by the lack of white "underpants."
  9. Agreed. Young Ruby-throateds are often dusky-crowned and dull-backed. Nothing of true ID importance is visible in the photo.
  10. Green-winged Teal have a narrow strip of white on the underside of the wings, with the leading and trailing edges being of similar darkness. Blue-winged Teal has a wider white center to the wing and the leading edge is darker than the trailing edge. Besides, the speculum is bordered by pale on leading and trailing edges, with the leading edge having a bit of a copper aspect, not wholly white. Finally, one can see a bit of a ghost of a second dark line on the face, below the eye, another feature of Green-winged that Blue-winged lacks (though Garganey sports it).
  11. The trailing (and "smaller") bird is certainly a Ring-necked. I don't see anything definitive to rule out Redhead in the second pic. I think that the strong crown:cheek contrast is a lighting artifact. Regardless, that contrast is not a feature of any scaup, either. The bird also does not look obviously smaller than the Redheads; even Greater Scaup is smaller than Redhead. See here for a bit about the usefulness of size comparison in duck ID.
  12. Whitish throat, white ear surround -- reasonable for Myrtle, particularly given the location.
  13. The words "coast of CA" pretty much rule out White-rumped. All the birds that show any reasonable view of the wingtips also rule out White-rumped, as the wings are nowhere near long enough. Given that they all look the same size....
  14. The pale braces are distinctive for Blackburnian
  15. Cooper's Hawk Ruby-crowned Kinglet Song Sparrow Savannah Sparrow Lazuli Bunting (note white wing bars)
  16. DCFL is darker and without the strongly contrasting rufous wing panel that your bird shows
  17. Most flycatchers -- in the US/Canada, anyway -- perch much more vertically. The postures in the good field guides (particularly Sibley) are accurate. Pay attention to them.
  18. https://cobirds.org/CFO/ColoradoBirds/InTheScope/54.pdf
  19. Skinny necks on the geese -- Canadas The duck is not any kind of teal (and Northern Shoveler is just a big, goofy teal) -- note the under-wing pattern, which looks fine for Gadwall.
