| The corvids of North America consist of one species of jackdaw, four crows, two ravens, one nutcracker, two magpies, and ten species of jays. |
| The brain-to-body ratio of crows, ravens and magpies equals that of dolphins and nearly matches humans. |
| Then, like magpies, they hurry back to their workshop loaded with wisps of lace and coils of steel mesh, strands of silk and ropes of jute. |

| Long-eared Owls usually nest in abandoned stick nests, often the nests of magpies, crows, ravens, or hawks. |
| Disturbance after eggs are laid provides opportunities for predation by carrion crows, jays, kestrels, magpies, foxes and mink. |
