Crows are among the most adaptable eaters in the bird world. They are true omnivores and opportunistic feeders - if it is remotely edible, a crow will eat it. This dietary flexibility is one reason they thrive in cities, suburbs, farms, and forests.
Crow Diet Overview

| Seeds and grains | Corn, wheat, oats, sunflower seeds |
| Fruits | Watermelon, grapes, cherries, berries, apples |
| Nuts | Acorns, pecans, pistachios, walnuts |
| Eggs and nestlings | Raid nests of smaller birds including Blue Jays |
| Small animals | Mice, frogs, small snakes, baby rabbits |

| Common Raven | Larger carrion, small mammals, more predatory |
Baby Crow Diet
| Stage | What parents feed them |
|---|
| First week | Regurgitated soft food from parents’ beaks |

Crow Intelligence and Feeding
| Behaviour | What it shows |
|---|
| Dropping nuts on roads | Use cars to crack shells - learned tool use |
| Caching food | Hide surplus food for later retrieval |
| Cooperative hunting | Work in family groups to find and share food |
| Washing food | Dip dry food in water before eating |
| Recognising human faces | Remember which people feed them and which are threats |
Crows are protected under the Migratory Bird Treaty Act. They recovered from West Nile virus population declines in the late 1990s and their numbers are now stable across most of North America. Their intelligence and dietary flexibility make them one of the most successful bird families on the planet.
