I can appreciate the use of the bicycle helmet. The babies are gone now but for a couple of weeks the male would dive-bomb anything that moved anywhere near the nest box, including our neighbor and our dog. Our golden-doodle was nervous about going in the back yard and would come running back in with blue boy swooping over her head.

Tammy, we do check the nest periodically. It does make sense that the birds would be more agitated when the babies are ready to fledge. That does not account for the aggressive behavior we’ve observed, though, since the male bluebird started acting more aggressive even before the eggs hatched. It is good to know that others have reported similar behavior on this forum. Thanks.

Hi, Carol,
Thank you for your response and helpful suggestions. We do not have our nest box on a wooden post. It seems to be unusual behavior inasmuch as we never saw this kind of behavior in previous seasons. Regards.
