What's your favorite thing about spring? This is mine: The tree swallows just came back today to start nesting. They're checking out the box on the shed. The bluebirds usually take that one but you never know. A few years back they took the box on the trellis and laid three eggs. A few days after they hatched I heard squawking and looked out to see feathers flying out of the box. I ran out and a wren had gotten in an tossed out all three of the 2 day old babies. I managed to save two of them and put them back in the box. They fledged a few weeks later. I look forward too and thoroughly enjoy their return each spring.
