Eastern Bluebird Family and Nestbox
Hi all. I have no idea what I'm doing and am not a birder, but after some research I discovered I have a bluebird nestbox attached to a large branch of a tree about 7-8 feet above the ground with Eastern Bluebirds nesting. Mom and Dad were very active the last couple weeks and I could hear the babies when a parent went to the entrance hole. Yesterday I noticed Mom and Dad are gone, I can't hear the babies and the nestbox is tilted slightly and it looks like the hole is plugged with nesting - possibly from the inside. My guess is a raccoon or a similar predator, but I don't know what to do next. Should I open the box and see what's up? Push the nest back into the box? Is there a way to save this family if it isn't too late??
