Bluebirds fledged a week ago and as of now all 5 are alive!
Now I have Tree Swallows actively building a nest in the same box the Blues were in.
Last year I lost 3 Swallow babies at 9 days old due to House Sparrows. I am trapping Sparrows almost every day, I have 2 males in my cage now.
My question is what, if any, precautions can I take to have a successful brood?
Now that I learned about the Chickadees, I hope I can help these guys!
