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.
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.”
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
- 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.
