Yes they do. In the UK where the grey (UK spelling) squirrel was 
introduced from the New World, it is one of the main bird egg 
predators, as well as having out-competed our timid native red 
squirrels so that they remain only in very isolated pockets on small 
islands and in remote mountainous regions. The level of egg eating 
might not be so high here in the US, as I think the UK populations of 
squirrels are at very high densities and use more "unusual" food 
sources in order to survive. Every spring my father loses up to 80% 
of the bird nests in his garden in Sussex, to a combination of 
squirrels, magpies and crows.
