sounds like a cuckoo - appropriately named! Both yellow-billed and black-billed could be in your area. They are tall and slender, and a distinctive ID trait is their long, barred tail. If you see the bird again, pay attention to the color of the bill. All black means black-billed. If the bottom is yellow, yellow-billed! Also look up their calls on the Cornell site, that may help you tell which species you heard/saw

Your correct, female house finch. Possibly immature

Location and date would really help but it appears to be a female house finch

Look into cormorants, species would depend on your location. I regularly see double crested cormorants flying in the way you describe

No worries, I saw your other posts so assumed where it was taken. Still a yellow billed cuckoo!

Yellow billed cuckoo - it would help to know where and when you saw this bird.

Yes to all

Try tree swallow, blue top and white bottom

Northern Cardinal for sure, either a young male or molting adult male.

Agreed - your Moderator is wrong. The bill is too short for red-breasted (or common), there is no coloration difference between the head and neck (like in red-breasted) and the overall shape of the bird makes this a hooded merganser.

Hooded merganser

Your correct, black skimmers. Awesome bird

Magnificent Frigatebird

This is a song sparrow. A lincoln's would have a lite buffy color to the breast and the streaks would be much finer.
