AWgh! Crows! I used to live in a suburbia near one town on Danube, and it had a huge number of the crows. Every single morning it was an orchestra.
Everyone were furious over the black shaiters, and complaining what kind of the awful sounds they make and what kind of a mess they leave on their cars.
Now, I had a feeling something really nasty is going to happen because crows were singing like that... so it was only a matter of time when a raven will join in to claim the territory.
The problem is that raven doesn't sound like that so when ever somebody ask what a hell was that, I was like ... It's Death, It came....'
Literary the blood freezing sounds. The shrieks were awful, but at least the crows stopped screaming.... lol
