My parents have a wren that nests outside their bedroom. He has decided that the best way to sing is hanging off the window screen and pointed into the bedroom. It's amazingly loud as the sun comes up.

I feed him because it's also hilarious.

Owls can be surprisingly loud, and annoyingly persistent.

I get barred owls around my place and they give me the creeps. Something in my subconscious knows they would eat me if they could

We have a m-f pair of great horned owls that live in the trees behind the house. Wild how loud they get at night as they’re patrolling the neighborhood together.

Try living in a forest that has howler monkeys. You really can't sleep through it.
