Ok, there's this bird call that's like: "Pee-yo-pee-yo" and sometimes "Pee-yo-pee-yo-pee-yo". My sister heard it as more of a "Hear-hear". The voice is sort of medium -toned, kind of like the Whip-poor-will's.It's a two-tone bird call and it's falling on the "yo" or "ar"(of hear).
I heard it in Massachusetts, near a forest. I've done the bird search a lot and had no luck. Any ideas?
