Bird calls.

I listened to recordings of many birds. I didn't hear anything exactly like this, but I think it might be a warbler, Northern parula, Bblack-throated blue, cerulean, and prairie warblers sounded sorted like this one, but I really don't know.

Thank you so much. You are always a great partner when it comes to nature identification questions.

Here's something that might help with identifying bird songs. I just found out about it.
