My brother who lives in Georgia was telling me about seeing a snake which got all 4 of his bluebird eggs. The nest had a wobbling stovepipe baffle on the pole, and he is trying to figure out how it got around the baffle and into the nest. Sounds like it was installed properly, with the wire at the top of the baffle so a snake could not crawl through. I forgot to ask him if there was a tree close enough for one to drop from the tree to the box, only thing I can think of. I remember that a year or two before he put up this baffle, he actually witnessed a snake eating one of the babies. So I told him about the baffle and he got one put up.
Not sure what State this took place in, but there was a YouTube video showing a snake bypassing a stovepipe baffle. Snake was black and super long, 5 to 6 feet. With the tail on the ground it could reach over the top of the baffle. We do not have that kind of snake here in Michigan. Bluebirders that have long snakes are using additional stiff netting ruffled up along with the baffle. The snakes can’t figure out how to get around the netting without getting tangled up in it.
Thanks, Judy – I will try to locate that video. I am really interested if anyone else has had this experience. I live in a rural subdivision and have these baffles up. Have not had any problem with snakes SO FAR on the nests, but with all the rain we have had this year we have noticed some small grass & garter snakes in the yard a few times. My poor brother was just devastated to witness this snake incident, or should I say incidents!
