A black crow superstition is that if it lands atop a home's roof, the inhabitants will suffer bad luck or face death. This superstition has existed for over a century.
The black crow, which is also called the American crow, is commonly heard and seen in the U.S. and other parts of the world. Part of the Corvid family, which includes ravens, and being omnivores, crows eat practically anything, such as nuts, spiders, snails and dead animals, including humans. With a normal lifespan of 6 to 10 years, adults have predators such as hawks, humans and eagles, with humans being their number 1 predator.
At one time, some Irish people likened the crow to a naughty fairy, which was capable of creating complications in their lives if they crossed paths with it.
