QUESTION: I successfully raised two families of Bluebirds last year. One day after I put up the house they were building a nest. I was sooo excited. Then came the sparrows and although the BB fought the sparrows, the sparrows continued building the nest. I destroyed the nest and they built another and I destroyed it. BB return daily but are not using the house. Will they every build in it again? Darn those sparrows!

ANSWER: They are called sparrows or killer house sparrows, but actually they ate alien weaver finches from Europe. They are not protected and you have to shoot or trap and kill them to be a successful Bluebirder. As they did not evolve here our birds do not have protection from their killer bills. I caught a female by hand in a nest on my line yesterday and she bit me so hard she actually drew blood. Even much bigger starlings can't bite that hard. If you will send your mailing address to me at I will send you my free Bluebird book that will tell you what to do. (Trap contacts, my email address for problems, etc.) Good luck1 Bluebird Bob Walshaw. PS - See page 19 for why you should have more than one box.

QUESTION: So, will the BB's ever use this house again this year?

Attacks or other disturbances do not seem to stop Bluebirds or other small cavity nesters from using houses again although they might discourage a pair that was attacked. Always remove a nest that has been attacked or disturbed and after a family of young fledge. Good luck, Bluebird Bob Walshaw.
