That is just so awesome. Not just to have the same female return, but to absolutely know it is her because of her unique color. I'm certain I have a different pair this year because they are very shy around me and don't come to the mealworm feeder when I call them. They won't go near it for about half an hour after I fill it. Also, this is the first pair I've ever had that built their nest out of short pine needles. In the past they have always used the long pine needles or grass.

Read up on sialis.org...it is full of information on Bluebirds and other cavity nesting birds. Bluebirds typically fledge 16-19 days after hatching. Do not open the nestbox once the babies are 12-13 days old to prevent premature fledging. Please make sure your nestbox is mounted on a slick metal pole with a predator baffle to prevent predators from getting to the nestlings. Houses mounted on trees/fences/wooden posts or un baffled poles are an easy meal for predators like raccoons, squirrels, cats, snakes etc. Good luck Donna
