dog whistle hz

i get a lot of phone calls and emails and letters from people who wokeup in the middle of the night thinking something terrible was invading theircampground when they suddenly were hearing barred owls. they're often doing that because they'rehearing another pair or individual barred owl on an established territory. and that’s when the pair starts reallyrevving up and making those territorial calls. one night i was being totally quiet, justwalking along this road and in flew two

barred owls. there was a full moon behind them, and you could actually see their eyes as theywere calling. and it was just magical.
