Crow. Have never heard one whistle song cooing like this. Please listen to more cooing call after initial caw to confirm. Thanks! Watched crow do this. At about 16 second in on recording. But then neighbor came up and said “it’s right there” and crow flew to a little higher branch so other cooing was a little softer on rest of recording. Interesting too that it attracted another crow to that tree just after. I believe it to be a wooing call for this group of crows on my street, https://www.audubon.org/news/hear-how-crow-softly-woos-its-mate
