Summary: The sight of hundreds of crows in the air might remind you of a scary scene of Hitchcock's movie "The Bird". However, in reality, they are not attacking people. They flock together in hundreds and thousands just because they enjoy the warm air in those parts of the region and want to meet up with other crows, which indicates they are sociable. There are other interesting characteristics about the black feathered birds. They are intelligent enough to make tools, and beneficial to humans because they catch insects. The only problems they cause are the noise they make and the mess they leave behind. No matter how citizens try to disperse them away, they can't manage to get rid of them.
Opinion: I've watched the movie "The Bird," which made me rethink about the birds; Are they so mean to attack people? But I know film is just film, which is not real.
On the contrary, I am fond of birds regardless of its species. I like sparrows, swallows, magpies, and maybe even crows. But I don't like the pigeons much.
By the way, in Korea, crows are believed to be omens. I don't know when this belief started but crows are related with 'deaths'. Is it because they are black? Or is it because the noise they make isn't as attractive?
