We have “crowbars” and “crows feet”, “as the crow flies”, and “something to crow about.” We also have Corvus brachyrhynchos, which is a heck of a name for the common crow. The North Beach is about midpoint in their Coastal Habitat, which reaches from Baja, California, to Northern Alaska. Being salt water oriented birds, they can be found on both coasts of the U.S., Canada, and Mexico. Regardless of where they are found, crows are gregarious, loud and aggressive, and are acknowledged as being the most intelligent of all birds as a species. Their family, which includes the Ravens, Jays, Nutcracker, and Magpies, have the largest brain for body size of all birds; are quick learners and associators, especially when food or danger is involved.
Weighing in at one pound each, with a wingspan of about 35 inches, and a body length of 18 inches, puts the crow into the medium-sized bird grouping. Mating season is late April through May in our area, and nests will be built in trees or high shrubs away from people’s activities; usually in colonies or groupings. The nests are constructed of sticks, heavy brush stems (including blackberry vines), and are then formed with mud and grass into a small bowl shape.
The inner lining may be made up of animal fur, moss, or other soft materials, even bits of cloth. After 4-6 blue-green eggs are laid they will be tended by both parents during the 18 day incubation period. Feeding, guarding, and caring for the young is a full-time project. If you feed the crows about this time of year, you will often see them fly off with what seems to be an excessive bill-full of fries or bread rather than eating it. They are probably “out shopping for the kids!” Feather growth is completed in about 25 days, and flight school starts with much encouragement from the parent birds. After a 10-day crash course in flying, the crows are nest-free and rejoin the local flock, and its daily hunts and adventures.
Being all black in color allows the Crow, and its larger family member the Raven, to live in the far Northern areas of Alaska and Canada, where the black color allows solar energy to be absorbed. Their feathers will change in spring-molt just before mating and again in the fall before colder weather sets in.
A Crow’s diet here on the beach will range from road-killed animals to whale meat. They do, sometimes rob other birds’ nests, but prefer something “good and dead.” Some are attracted to gardens for grubs, worms, and a little fresh produce once in a while. They eat anything we will, and learn which houses are worth hanging around! Living up to 20 years in the wild, they grow progressively smarter each season or after each event.
Often when one bird is injured or trapped, a flock will gather in a mob to drive off the predator by sweeping close, calling loudly, and making attack-like motions.
The calls and vocalizations we hear range from those of other birds to the sounds of children calling. They understand each other, and we people have no trouble recognizing most of the calls; especially those for food, danger, or mustering. They can be taught to speak human words and will associate those words with individual people.
We had a three-year resident wild crow in Ocean City who would call “kitty, kitty” and say, “hello.” Rewards were always given, and this probably reinforced the speaking pattern.
Splitting a crows tongue to teach it to talk is an old wives-tale and surely leads to a dead crow. Being kind to your neighborhood crows will ensure the rapid clean-up of dead animals, removal of tons of grubs, caterpillars, and other insects. It will also provide you with hours of enjoyable observation; that is, unless you’re a “scarecrow.”
