We have blue jays in NorCal. They love to use their beaks and shovel ALL the birdseed ~OUTT of the feeders. Nasty bastards - tho the squirrels love it because it's a massive seed spill everytime a jay perches on the feeder and begins the malicious shoveling.
DaMomInLaw's backyard getts northern Cardinals every year. They are very pretty and usually are matched male/female pairs. DaMomInLaw is a cardinal fanatic. Her house is full of cardinal stuph.
