Eurasian Jackdaws are diminutive crows, easily recognizable by their gray-on-charcoal color pattern, pale eyes, and piercing calls. They are at home in towns and cities, where they nest in chimneys, forage on lawns, and roost in wooded parks. Jackdaws are very social birds, gathering in flocks to feed together and ply the wind in coordinated, acrobatic flight. They typically feed on invertebrates, fruits, seeds, carrion, and even refuse, but some individuals learn to raid nests at seabird and heron colonies.More ID Info

- Cool Facts
- Some individual jackdaws get good at raiding the nests of other birds and have caused significant egg loss in both Common Murre and Gray Heron colonies. Some even work in tandem to prey on seabird eggs, with one jackdaw luring incubating Atlantic Puffins or Manx Shearwaters out of their burrows so that a second individual can take the eggs.
- Jackdaws work hard to maintain their pair bonds. On regular nest visits throughout the year, they preen each other and the male feeds the female as part of a courtship behavior.
