Crow Habits And Biology
Crows, despite being loud and boisterous, for bird brains, are considered one of the most intelligent animals in the world.
They are famed for their adaptability and are even known, like human beings, to use common sense.
The New Caledonian crow uses sticks in the wild to lure ants out of their nests.
They belong to the genus Corvus along with ravens and rooks and the family Corvidae, which compromises other birds such as magpies, nutcrackers, and jays.
There exist about 40 different species of crows that vary in size, ranging from 24-27 inches (53-69 cm) long. The fish crow measures about 19 inches (48 cm) long, while the American crow measures about 17.5 inches (44 cm) long.
Crow’s weight ranges from 12 to 57 ounces (337 -1,625 grams). Some of the most common crow species include:
- The Common Raven
- Carrion crow
- Large-billed Crow
- New Caledonian crow
A lot of crows are reclusive, although they often scout for food in groups. An adult needs 11 ounces of food daily for sustenance.
During nesting season, they gather in large numbers to roost and protect themselves from predators. They can eat up to 40,000 grubs a day, including; armyworms, caterpillars, and other insects considered pests.
Others live in groups called “murder.” When one of them dies, the murder gathers around to mourn the deceased. Some detective work is done.
Once the crime is solved, they act together to chase the predator away in a behavior known as mobbing.
If you thought it couldn’t get any better, think again. Crows have their own language of communication, using over 250 different calls to communicate additional messages. Distress call brings other crows to the aid.
Crows only take up one mating partner for life. They exhibit a variety of breeding and incubation depending on the species. Incubation typically lasts for about 18 days, and the chicks mature at four weeks old.
Crows may live up to 13 years in the wild and up to 20 years in captivity.
