That dark brown compact appearance with silver based primaries made me think Murphy's Petrel at first glance. But that would be shockingly rare at this time of the year, so definitely wait for more opinions.

Confirmed! Note the white below and brownish above with reddish wings and tail.

I agree with Gray Kingbird. The similar Loggerhead Kingbird would have a big-headed appearance, a darker-colored head (as an adult), and a white-tipped tail.

Female/immature Indigo Bunting is correct, due to the faint streaking on the breast, tan wingbars, and white throat.

1. and 3. Lesser Antillean Bullfinch 2. and 10. Carib Grackle 4. Gray Trembler 5. Gray Kingbird 6. Magnificent Frigatebird 7. Lesser Antillean Saltator 8. Laughing Gull 9. Royal Tern

Common Goldeneyes are known for their distinctive whistling sound; I think that at least some of the others on my list have a more whirring sound.

These are some ducks that I know that have a whistling/rattling sound during takeoff or in the air: Northern Shoveler Green-winged Teal Common and Barrow’s Goldeneye Common Merganser

Interesting. I thought that this bird had too green of a back for an American.

Looks like a Lesser Goldfinch.

Yes, this is a young Bald Eagle. To separate eagles from other types of raptors, note the heavy body, large head, and long, hooked bill. Young Golden Eagles don't have white that close to the body.

These are Gray-crowned Rosy-Finches. Black Rosy-Finches have a much darker (almost black) overall.

That's actually a leucistic Black-capped Chickadee. Leucism is a condition in which there is partial loss of pigmentation in a bird or animal. In this example, it's on the head. Nice find!

Welcome to Whatbird! I'm pretty sure you saw a Varied Thrush. https://www.allaboutbirds.org/guide/Varied_Thrush/id

Just a photo artifact. It's quite common for black to appear blue in photos, and this doesn't have to happen throughout the photo.

It’s not easy to sex Barred Owls in the field, as it’s a sexually monomorphic species. Females are generally larger than males, but this is only obvious when they’re next to each other. Also, female calls are consistently (probably almost always) higher in pitch than the male’s, but again, it’s not easy unless you have taken an audio recording or regularly sexed Barred Owls by call in the field before. Finally, it’s not the best time of the year to analyze behavior differences (such as mating/rearing chicks).
