Arboretum nest cam...first egg

There was an egg visible on the Arb Cam nest this morning but I just watched the male standing on it, covering it, kicking it, digging around it. (The egg has been covered, uncovered and has now found its way back into the center of the nest.) This is behavior that has been seen on several other nests on other parts of the world also. He must think it's not his egg. The female was not incubating it. We will just have to keep watching and see what happens next. There may be more eggs that he will accept. It's been a stressful spring for these Ospreys and I think that is being reflected in these behaviors.
