I love Spring for a lot of reasons but mostly it's because we start a new bird nesting season. With and early Spring the birds are getting an early start. This Bluebird nest is almost done and we have seen the Tree Swallow and other Bluebirds checking out the other 2 boxes.
Here's an aerial view of where the boxes are located. #3 is nearest to the garden and the house.
It's too bad that they took the aerial photo in winter when everything is so brown!
