Here is a new one on me. I was able to take a movie clip today of a male Eastern bluebird purloining nesting material from a chickadee nest while the nest building process is still active. The female chickadee came in right behind the bluebird and continued building the nest.
Apparently the male bluebird is trying to entice his mate to occupy a nearby nest box by putting the nesting material in it. She keeps looking into the box but so far has not selected it for nest building.
