I feed the songbirds, but draw the line at birds of prey. Feeding raptors can make them associate food with people, and cause issues like owls getting hit by cars while crossing roads coming in for an expected meal. I've seen videos of people baiting owls, and then taking the rodent away from the owl which really frosts me, and then you get the ones that tease them by using cat toy mice on fishing line all the while these birds are hunting to survive. I've always enjoyed watching wildlife and studied wildlife management in school. Photography is a useful way to document what I've seen/observed, but I wouldn't do some of the stuff I've seen people do in videos online.
Jeff started this thread a while back. It was very interesting.
