One study in Alaska showed ravens have more than 30 distinct vocalizations. The female lays from 3 to 7 eggs. The chicks hatch after about three weeks and grow quickly, leaving the nest about four weeks after hatching. Both parents feed the young by regurgitating food and water which is stored in a throat pouch. In the Interior, young ravens leave the nest by the first week of June.
Ravens often form loose flocks during the day and congregate for roosting at night.
As many as 800 ravens have been seen in one roost near Fairbanks. Ravens do not undertake long migrations like many birds, but breeding birds usually relocate for nesting each year. When not breeding they may travel 30 to 40 miles each day from roost to daytime feeding areas. Ravens consume a wide variety of both plant and animal matter. They are notorious scavengers and are at times predatory on small animals.
