Hey, it’s Cinco de March-o.
Crows are intelligent, clever enough to solve complex puzzles, and find solutions to problems that crop up.
Crows are so smart they can make enemies. They can also remember, and recognize them in the future, not just a cat,
dog or human, but specific individuals. Japanese Crows do what they must to get on with life.
Quote:
Food isn’t the only motivation factor that drive crows to adaptability. Crows also demonstrate intelligence when building nests, using whatever materials that are available to construct them. A typical nest is composed of interlocking twigs, often recycled from the old nest, and pieces of wires of various lengths and thickness, gathered from the surrounding, to strengthen the nest structure. Tokyo residents have observed that crows in the city have learned to use coat hangers instead.
In such a large city, there are few trees, so the natural materials that crows need to make their nests are scarce. As a result, the crows will often steal hangers from the people who live in apartments nearby, and carefully assemble them into intricate nests. The completed nests almost look like works of art.

Nests built from hangers were also discovered in other Japanese cities. In Fukuoka City, the Jungle Crow would often make nests atop power lines during the breeding season that could cause large blackouts due to short circuiting. The Kyushu Electric power company actually has "crow patrols" that search out and destroy hanger nests on their power grid.

The Crow’s reaction to the “Crow Patrols” is to build dummy nests away from real ones.
Tokyo’s Governor Ishihara, after a crow buzzed his head while he was playing golf, declared war.
Between 2001 and 2008 they killed 93,000 birds... didn’t put a dent in them.
