dag nabbit - fast clicked too fast for the ID of the Kestrel!

Pics 1 and 2 are indeed osprey Pics 3 and 4 are peregrine falcon!

This is a female hairy woodpecker, the bill is too long to be a downy

This is a female downy woodpecker based on the barring on the back, short bill and lack of red on the back of the head Sniped! I should have known I wouldn't be the first🤣

This sounds like it could be a female rose-breasted grosbeak. I have seen them eating oranges at our feeders.

I don't have access to the (pretty terrible) pics other than my ebird list (below). First male golden-wing we have ever seen, is this pure or does it appear to be a back-cross hybrid? There was some slight yellow on the breast which most books do not sure for pure golden-wing. Note that the bird had no tail. It sang the traditional golden-wing song twice. https://ebird.org/atlasny/checklist/S69133017

Agree with Cape May Warbler

Not brilliant white but the rest fits - ruby crowned kinglet?

Thanks for the reply's! We have a lot of planning to do but this helps greatly. I'll focus in more once we start getting the dates and locations sorted out

You are correct with Pine Warbler

Young or molting male goldfinch is correct

We are planning to visit friends near Boulder next year and I am trying to focus my time for the "best" birding. We have never birded west of the Mississippi except for Houston and Hawaii, so many birds will be new. We have flexibility in the month we go, I am thinking mid May to mid June would be best for maximizing birds but am open to suggestions (migration?). We will be doing a lot of birding during the visit so can travel a distance from Boulder. Any advice is welcome!

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
