There are lots of Cardinals, some Robins and even a Bluejay living in the woods behind my apartment. There are a couple doves too, but they don't get too close. We've got some feeders on our porch but a flock of sparrows chases off the other birds so we don't get to see them often. I popped one today with my pellet gun and even with the bird in my hand I couldn't tell if it was a House Sparrow or a Tree Sparrow. Does anyone know if native American sparrows are aggressive like that? I know the House Sparrow, which is non-native definitely is aggressive. I would feel better about popping these birds if I knew for sure they weren't native. Hopefully I can get the sparrow flock to move on without scaring the birds of color away.
