Crows are among the most intelligent of birds. Experiments indicate that American crows can count to three or four, are good at solving puzzles, have good memories, employ a diverse and behaviorally complex range of vocalizations and quickly learn to associate various noises and symbols with food.
Crows can mimic sounds made by other birds and animals and have been taught to mimic the human voice. Crows begin nesting in early spring February to May, with southern nests starting earlier than northern ones and build a nest of twigs, sticks, and coarse stems ranging from 18 to 60 feet 5 to 18 m above ground in oaks, pines, cottonwoods or other trees. Crow pairs appear to remain together throughout the year, at least in nonmigratory populations, and pairs or pair bonds are likely maintained even within large winter migratory flocks.
The female incubates the eggs and is fed during incubation by the male and nest associates. The young leave the nest at about five weeks of age and forage with their parents throughout the summer. Later in the year, the family may join other groups that in turn may join still larger groups. The larger groups often migrate in late fall or winter.
Few crows in the wild live more than four to six years, but some have lived to 14 years in the wild and over 20 years in captivity.
A bird bander reported a crow that had lived 29 years in the wild. A communal roost site in the Fort Cobb area in Oklahoma holds several million crows each winter.
In Nebraska, Wisconsin, and possibly other states, crows appear to be roosting in towns near people. These flocks roost together at night and disperse over large areas to feed during the day. Crows may commonly fly six to twelve miles 10 to 20 km outward from a roost each day to feed. Complaints associated with crow damage to agriculture were more common in the s than they are today. Although surveys indicate that overall crow numbers have not changed appreciably, the populations appear to be more scattered during much of the year.
Farming has become more prevalent in some areas, generally with larger fields. Woodland areas are generally smaller, and trees and other resources in urban sites provide crow habitat. Overall, the amount and degree of damage is highly variable from place to place and year to year.
Several variables enter into the complex picture of crow damage, including season, local weather, time of harvest, amount of crop production, and availability and distribution of wild mast, insects and other foods.
Many of the problems caused by crows are more commonly associated with other animal species. Crows may damage seedling corn plants by pulling the sprouts and consuming the kernels.
Firearm any valid Nov 13 to Jan 4 for all deer season. Actual updated regulation summaries appear based on the wildlife code of Missouri that help keep the habitat healthy.

The nest is cup-shaped, built of twigs and sticks, and lined with finer material. The female lays four to six eggs that she incubates in 18 days. The male feeds the female while she incubates. The young remain in the nest for 28 to 35 days. Both adults feed the young while they are in the nest and for a short period after they fledge. Facebook Twitter Email.
