Chihuahuan Raven vs Forest Raven

Chihuahuan Raven

Corvus cryptoleucus

Large534 gGrassland

The proportions resemble the common raven with a heavy bill, but is about the same size as a carrion crow, or slightly larger than the American crow (44–51 cm (17–20 in) long). The plumage is all-black with a rich purple-blue gloss in good light. Like the forest raven, little raven, fan-tailed raven and Australian raven, it is one of the smaller raven species. Voice: The voice is similar to that of the common raven with "pruk-pruk" sounds and other croaks at slightly higher pitches. Like all corvids, the Chihuahuan raven is capable of vocal mimicry. However, this behavior is mostly recorded in captivity and rarely in the wild.

Forest Raven

Corvus tasmanicus

Large676 gWoodland

The largest of the Australian corvids, the adult forest raven is 50–53 cm (20–21 in) long with a wingspan of 91–113 cm (36–44 in) and weighing approximately 650 g (1.43 lb). There is no seasonal variation in plumage, which is entirely glossy black with a blue or green sheen visible on the upperparts. The wings are long and broad, with the largest of its ten primary feathers (usually the seventh but occasionally the eighth) almost reaching the end of the tail when at rest. The tail is rounded or wedge-shaped. It is quite short in Tasmanian populations but longer in northern New South Wales. Voice: The call is considered the most reliable means of identification in areas where the forest raven's range overlaps with other corvids. It is a deep and husky "korr-korr-korr-korr" with a similarly drawn out last note to the Australian raven. It can also utter a barking alarm call. The calls of juveniles have a higher pitch than those of adult birds.
