we ran out of birdseed so we put peanut-butter in the feeder and went inside to see what would happen. first the sparrows came and hopped forlornly about looking for seeds. then a bluejay swooped down, scattering the sparrows. it scooped up beaksfull of peanut butter, stopping after each each bite to strop its beak clean on the side of the feeder. finally a tufted titmouse arrived. it too liked the peanut butter. it was a much smaller bird than the jay, but it ate at least as much, and even after we got another sack of seed we kept putting out a dollop of peanut butter for »the peanut-butter bird,« as my son called it.
