Like Clockwork

A Cuckoo Clock.

With a Yellow-billed Cuckoo in this case.

And while you may not be able to set you clock by the arrival of this bird, you can surely set you calendar by it. If Cuckoos are here it must be May.

Another migrant species which stops when it gets here, and which breeds in our woods, as they like woodlands with water nearby. And that is here for sure.
