Its very greenish, therefore it's not Willow/Alder. This is an Acadian Flycatcher

If reputation is important to you, I would highly recommend that you don't report it, other than as bird sp. w/ comments. Birding is full of instances like these, where you think you might have had something rare, but at the end of the day no one will ever know. And that's just birding. However, there are just as many times that you think you see something rare, only to discover it's a common bird. A reputation as a stringer is really, really hard to come back from and takes years.

The issue is not if it's a Pewee, which it obviously isn't, but if it's a flycatcher. I agree that it might be, but I'm not totally convinced it's for sure a Flycatcher

Why is the last an empid?

Yes

I'm not much help, but there's definitely an Anna's Hummingbird in the recording

I agree with Canada Warbler, though a pretty weird song honestly

Eastern Wood-Pewee

Bachman's Warbler is certainly extinct, and even if it wasn't, it was a secretive and sulky bird. I doubt you'd see one out in the open, perched higher up on a small twig

This is a Song/Savannah Sparrow

I don't have an issue calling the last bird Blackpoll, it's pretty bright yellow with no hint of buffy on the sides

1-4 Cape May 5 Baypoll, I believe, due to the non-yellow rump and two wing bars 6 Pine? Honestly unidentifiable though. I agree it's not Cape May 7 Cape May 8 Cape May, I think

The large bill and structure

Sedge is far more compact than this bird. It's round and tiny with a short tail and short bill, unlike your bird which is elongated. In terms of color, your bird is a dark brown overall. Sedge is a very light straw color. Honestly Sedge Wren is a tad more similar to the grassland sparrows (i.e. Grasshopper, LeConte's, etc) in terms of behavior and field impression than House or Carolina Wren.

This is a House Wren. Sedge looks quite different from this bird, and habitat preference of that species is associated with grassland areas

Traill's is grayish rather than yellow green as your bird is, particularly in the first photo. Your bird appears to have a prominent eyering, and that bill is very large. Structure also feels off to me for Traill's.

What appears to be a significant bill, head shape, and thinner eyering are all inconsistent with Yellow-bellied

Tennessee

This looks perfectly fine for Acadian

Yes

There's no reason this can't be a Forster's. It's easy to find photos of Forster's this time of year that share characteristics with your bird: https://macaulaylibrary.org/asset/110323291 https://macaulaylibrary.org/asset/68400911 At best this is unidentifiable, but it's almost certainty Forster's

This is an Acadian Flycatcher.

First bird is a Traill's

Definitely Cape May

This is definitely a chimney swift. A great study bird as well because the bulging inner primaries (the main field mark vs Vaux's) are super obvious here
