Up a tree

I was in Bath, Ohio today so I decided to stop and see the great blue heron rookery. There are several large trees where the herons have their nests. Every February they start to return from their vacations down south. The early ones get to choose the prime nests with the stragglers getting the left-overs. There are at least 20-25 nests in each tree with each pair having between 2-5 little ones. It's a little late for pictures, the foliage is getting heavy.
