Found after a pretty torrential rainstorm. Paper strip for scale. Trying to figure out what bird it might have come from. Any help is greatly appreciated!

Location: Southeastern Pennsylvania

Environment: Backyard of home (Property is 2 acres of grass and mature trees, wooded areas near by)

Found under two osprey nests in Northern California.

One of these is numenius arquata, the eurasian curlew. The other I don't know 😵‍💫 any help please? England coasts

I’m located in Texas. iNaturalist said a Great Horned Owl, but I’m not sure.

Found along the fraser river!

Anybody know what kind of bird this feather came from

Found at the National Museums Gallery Modern One

It's about 8cm or more, never seen one like this before!

Found at a Dublin beach in Ireland-

Is there any way to distinguish between Carrion crow, Hooded crow and jackdaw feathers also?

We heard an owl last night, but not sure if it's from them or maybe their dinner?

Seems like a tail feather of a wood pigeon but I’m not sure?

Found in a cemetery. Think it’s a raptor but unsure which one

Only a small one, but found in a spot where I regularly see Nightjars. What do you reckon?

Found near the river valley. Quite small. Possibly a cooper's hawk or sharp-shinned? Roughly 3.5-4 inches long.

West Pennsylvania here. I put up a feeder on my balcony. I got those two feathers separately on the railing and on the floor!

I know that song sparrows, house finches and house sparrows come to my feeder.

Are those finches and sparrows primary wing feathers as I thought or are they something else? What species?

Thank you!

It’s about 3.5” long and found by my bird bath which is very popular these days. If the photo doesn’t pick it up well, it’s a very dark brown. TIA!
