I've not heard him sing anything else. He lives in the trees right by my house...
Also, I have a barn swallow nest with 3 solid white eggs and one brown-spotted egg on my front porch. I have seen no activity around the nest for two days now. Could the white eggs belong to the 'bay beee bay booo' bird? I have never seen him.
I have just retired and moved to northeast Texas about an hour east of Dallas... birding is new to me!
