As I sat cogitating last night thinking tilty crap I noticed, not for the first time, mind you, just because it was extremely loud, the ululations, nay, buzzations of the tree frogs and whatall that live in the trees at night.
The first time I heard the blaring I really honestly thought we had orangs or maybe some smaller monkeys or something living in our yard. It's like cicadas only with rhythm. Pulse, throb, pulse, throb-ZZZZZZ ssss ZZZZZZ ssss in a bit of an atonal, definitely minor key.
Last night they were partaying HAHD. And if they'd stopped I would have known a predator of largish dimensions would be in the yard. Noise is good sometimes.
