Sorry I haven't posted lately. We've had such fantastic weather this spring that I haven't yet caught up with uploading all the photos onto my computer. We put up a Bluebird nest box on April 24th, and Tree Swallows claimed it on May 1st. Here is the female on the roof of the box on May 6th, pausing for a moment before taking straw into the box. Sadly, Bluebirds drove the Tree Swallows out on May 10th. But we put up a second box on May 19th, and now a new pair of Tree Swallows is building a nest inside it. (Well, the female is, anyway.) The Bluebirds are still using the first nest box, and now there are 5 eggs inside!
