These recordings are from today in WNY. I’ve been hearing/seeing this bird for about a month now at sunset. It’s too hard to make out what it is because of the light level but today I finally got some recordings. I thought it matched a Merlin based on the frequency of the call but the pitch doesn’t match. There were two smaller birds (what I assume to be the ones calling) and one that was a little larger. They would sit at the top of a pine tree and then all fly off and call together.
