Crows are laying eggs now, so vigilance against thieves is in order (I imagine the extended family participates in this). The West Danby Ravens are accomplished egg-thieves, and now have nestlings to feed. Even the Canada Geese are apt to be robbed. I've found their huge empty eggshells on the forest floor in the vicinity of Ravens's nests, a mile or more from the nearest goose nests!
