Tracks

Crows spend a lot of time on the ground, so sometimes you can see their tracks. Look for patterns where three thick toes point forward, and one long toe (equally thick) points back. The total length of a print is approximately 3 inches.

Sounds

The normal crow call is a loud caw or awk. The male also makes a dry, rattling call, very different from the normal call. If you are very fortunate you may hear the soft, almost melodious song of the crow. To hear what a crow sounds like, the Cornell Lab of Ornithology provides sound clips for crows on their 'All About Birds' website.

The Crow

Crows are considered to be among the most adaptable and intelligent birds. Crows are omnivorous and will eat almost anything. Thy are found in many different habitats, including woods, meadows, marshes, fields, riparian areas, towns and cities. Although solitary or seen in pairs much of the time, crows can also be gregarious; during the fall and winter they may gather in very large roosts near a source of food.

If presented with the opportunity, crows will consume eggs or young chicks and ducklings during the nesting season. Also, crows are known to harbor the Histoplasma capsulatum fungus which causes histoplasmosis.

Regulatory Law
Crows are protected by the Migratory Bird Treaty Act, a federal act resulting from a formal treaty signed by the United States, Canada, and Mexico. However, under this act, crows may be controlled without a federal permit when found “committing or about to commit depredations upon ornamental or shade trees, agricultural crops, livestock, or wildlife, or when concentrated in such numbers and manner to constitute a health hazard or other nuisance.”

Exclusion

Keep birds in a secure enclosure : Install aviary bird netting over top, or ideally, use hardware cloth with reinforced supports

Remove attractants : Clean up any spilled grain or feed, birdseed or fallen fruit

Frightening

  • Lines : Stretch a cord or fine wire at intervals at heights of between 6 and 8 ft (1.8 to 2.4 m) above the ground. Tie aluminum pie pans or cloth strips to the wires.
