4. Bat boxes are very good. Bats eat mosquitoes. Thus, less mosquitoes, less bites... less bites, less infected prey... less infected prey, less sick crows... Less sick crows, happy crow lovers... more crows, better life!(;
I am very confident that I can tell crows and ravens and, yes, the "blackbirds" apart. Crows are party birds. They do loops in the air and are very noisy; they also have rounded tails and shorter neck feathers than ravens. Grackles have long tail feathers and, sometimes, yellow eyes. Ravens, however, have diamond-shaped tails and longer neck feathers than crows. I hope these tips help! (:
1. I would probably tell my neighbor that squirrels kill more baby birds than American Crows; if they did not believe me, I would simply tell them about the study showing how squirrels and chipmunks kill more nestlings than raccoons, cats, and weasels, and that squirrels kill almost as many baby birds as snakes. If she (or he) still complains, I would probably say "I'm sorry you feel that way." Then, I would probably leave. :)
