...might be a bad idea. Because, apparently, the British fondness for attracting birds with feeders is actually causing evolution. Specifically, British great tits (which aren't very "great" at 4.9-5.5 in long unless you compare them with other tits) have a longer beak than those in the Netherlands, where people aren't as inclined to feed them.
Maybe it has to do with bird feeder design? (They're still adorable, though).
