We have a pair of Scrub Jays that have been around for several years. At the beginning of Spring they built a nest in their usual spot in a tree next door. Then, they built one in a tree in our yard, produced at least one young 'un, and now have moved on to another tree to build yet another nest. Not sure what happened to the youngster - it wasn't old enough to be independent when they started on the third nest but the nest is empty. Very odd, is this usual? We also have a big white pigeon that has taken up residence under the eaves. Had a different one last year. Is it weird to have pigeons here?
