Yeah, we definitely don't feed the birds, there's really no reason to. They're all over the place and always have plenty to eat - like our blueberries and wild black raspberries, for instance...
We deal with rodents rather more aggressively, with multiple outdoor traps around the house and two perfectly-capable (but mostly lazy) cats who spend most of their time outside. My wife is soft-hearted in almost every circumstance, but mice and their brethren receive no mercy! That time they got into our kitchen cabinets... oh boy, the rage and ensuing Maoist purge was breathtaking.
