About the Northern Raven
The common raven or northern raven is a large all-black passerine bird. It is the most widely distributed of all corvids, found across the Northern Hemisphere. There are 11 accepted subspecies with little variation in appearance, although recent research has demonstrated significant genetic differences among populations from various regions. It is one of the two largest corvids, alongside the thick-billed raven, and is the heaviest passerine bird; at maturity, the common raven averages 63 centimetres in length and 1.47 kilograms in weight, up to 2 kg (4.4 lb) in the heaviest individuals.

ID tip
A mature common raven ranges between 54 and 71 cm (21 and 28 in) and has a wingspan of 116 to 153 cm (46 to 60 in). Recorded weights range from 0.69 to 2.250 kg (1.52 to 4.96 lb), thus making the common raven one of the heaviest passerines. Birds from colder regions such as the Himalayas and Greenland are generally larger with slightly larger bills, while those from warmer regions are smaller with proportionally smaller bills. Representative of the size variation in the species, ravens from California weighed an average of 0.784 kg (1.73 lb), those from Alaska weighed an average of 1.
