New birds are arriving every day from the south.
In the past week I’ve seen three kinds of swallows (tree, barn, and northern rough-winged), plus blue-gray gnatcatchers, ruby-crowned kinglets, a yellow warbler, a common yellowthroat and many chipping sparrows.
I enjoy watching the swallows but they’re hard to identify because they move so fast. Sometimes I have to identify them by voice. The northern rough-wings make a spitting sound. The tree swallows make a chatter all their own.
Bobby Greene captured these two tree swallows having a conversation.
Or was it an argument?
