Nice pics. I've been enjoying watching my family (maybe 2) of bluebirds that hatched out here and are now flying around continuously. Parents are still bringing them food. We've had successful nesting of those, chickadees, cardinals, several wrens, red shoulder hawk, and robins (although I never found their nests). We've got about 1/2 dozen hummers. We use to get 25 or more. Pretty good year so far.
I have all 4 of my bluebird boxes checked, cleaned, and ready to go. Hopefully I'll get more this summer.
