Hope that helps and best of luck.By the way on most of the older vehicles for example 90-97 etc you can disconnect the battery for a few minutes without any headaches but on many of the newer models the dealership may have to reprogram the whole ignition/stereo security and alarm systems.
Best Answer: Yes, definitely. Squirrels are common nest predators and can and will eat eggs and baby birds from nests. Edit: This occurrence is NOT rare as Mikey states..I specialize in nest searching and monitoring and have seen squirrels depredate nests firsthand.
The main predators of robin eggs are blue jays, crows, snakes, squirrels. Deer eat a lot of bird eggs and nestlings, too, but only from ground nests. Snakes swallow eggs on the spot, and since you found one egg in the yard, a snake most certainly wasn't the culprit. Squirrels usually stay up in branches, and seldom drop their eggs, so I'm betting it wasn't a squirrel, either.
