That is more than impressive!
When I moved to the Washington, DC area, I didn't see any for a few years! This year is the first time I have seen them (in abundance too) They have taken over one of the birdfeeders and won't let anyone else near it. :)
Except for the cardinals. How odd?
Haha only the cardinals are mean enough to take on the jays and only the squirrels are tough enough to scare off the cardinals.
