Ruthven Park was full of bird song this morning, but mostly of local residents announcing their presence to the world. A few migrants were around, Blackpoll Warblers and Empids for the most part, but now young fledglings are coming to the forefront. A pair of young Eastern Bluebirds spent much of the morning chasing around a male demanding (loudly) to be fed.

A trio of American Crows descended upon the back parking lot and seemed to be working cooperatively in order to predate the young Killdeer. One crow would hide behind a clump of vegetation while the other two chased the Killdeer towards the hidden one. They weren’t successful, but it was interesting. Of course it may not have been cooperation. One may have decided to let the other two chumps do all the work.

Another Luna Moth was perched on the wall of the washroom building. I think this is the 4th or 5th sighting this spring – more than we usually have.
