As the sun sets over the French Quarter crows settle for the night in the magnolia trees surrounding the Louisiana Supreme Court building, bottom right, in New Orleans. Crows frequently gather in large, noisy groups, often called "murders," at sunset, especially in cooler months, to form communal roosts for protection against predators, some warmth, social bonding, and sharing information about food sources found during the day.
