The Jays know how to keep their young families safe from cruising ravens. They build under, usually under an overhanging roof if they can find one. We’ve been raising Stellar Jays for many years. I like to think it’s great great grandchildren returning every spring. The one on the tree branch is really a squirrel nest but the Jays play around in it, too. We raised two families this spring. I think they’ve abandoned the one in the rose bush that they used for years because we use the deck out there now at that time of the year and they feel that’s a little close, I suppose. But the other two are on opposite sides of the house. The first one is the newest nest. Randy put up the shelf brackets and strung chicken wire between them as a platform. It was in self defense as they wanted to build in his supply of fence panels and we were going to be needing them!
But the subject is architecture. They build rather free form but it is a tight and sturdy nursery. And safe, as I have mentioned. We have other birds around but these are the only ‘house’ birds. I had a house wren build a nest in the pocket of a pair of my pants which were hanging on the clothes line. By the time they were done with it the pants were pretty faded but I could not bring myself to oust them.
