Early Saturday morning at Tyson bend wildlife Management area. I heard a black billed cuckoo. It said "coo, coo, coo", paused, and repeated. It would sing for 30 seconds to a minute stop and then start up again a few minutes later.
And here's a cautionary tale. I recorded the song on Merlin. Then I closed the app. On my old iPhone, all my bird songs were automatically saved. But on my new Google phone. I have to select save. I didn't select save.
I do have a short video that I believe includes the black Bill singing. If anyone would like to hear it I can upload it.
