Here in Georgia, my nemesis is the Blue Jay. The only more annoying bird I can think of is an African Gray parrot. Blue Jays apparently feel that 5 to 6 am is the time to get up and start screaming in my neighborhood. I’ve hated them since I was a small child.
Last summer, I was awakened at dawn by the calls of every local bird imaginable. Cardinals, robins, jays - and more. All right outside my bedroom window. Non-stop.
Saturday morning, well before 8. I was so pissed. I lay there under the pillows trying to drown it all out, but to no avail. Finally, I jumped out of bed, threw the window open and started screaming like a maniac to the avian world in general, describing exactly how each one would die when I got back with my gun.
And there, perched on a branch not 3 feet from my big mouth, sat a small Barred Owl no bigger than my fist. I stopped in amazement at first, then laughed my ass off at all these birds upset at the apex predator endangering their forest. I looked around and could a dozen different birds hopping around the branches, keeping their distance like wary boxers.
They weren’t brave enough to come near enough for a blow, but they were making damn sure that everyone in the area knew exactly where the danger was.
I got the kids up to see, I got the video camera, and we watched the little guy just sit there all alone for 30 minutes, just surveying the land. He wasn’t at all disturbed by our presence, even though I probably could have reached out and touched him if I’d wanted.
During that time, we heard Momma Owl hooting nearby, and some smaller hoots as well.
Clearly today was the first day out of the nest. When he flew to a tree out front, we followed, and watched as he joined up with two of his nestmates to assess life in the Great Big World.
They eventually left and the birds all went about their business, and I never got back to bed.
As for the crows, your local laws will apply, but for the quietest firearm solution (assuming you don’t have access to a suppressor) look for Aguila Super Colibri (no powder, just primer), or Aguila Super Sniper Subsonic rounds in .22. These are very quiet rounds that won’t disturb the neighbors.
Good Luck.
