Australian Crow vs Chihuahuan Raven

Australian Crow

Corvus

How to recognise an Australian crow?

General appearance

Australian crows are large, robust birds, often mistaken for ravens due to their pitch-black feathers which display a slightly glossy sheen. White patches of feathers are rare but can occur. They have solid muscular legs and stout black beaks.

Male vs female

There is little sexual dimorphism in the Australian crow species making it hard to differentiate between males and females. Size tends not to be a reliable indicator of sex, as both are generally of similar size. However, vocalizations can be a good hint since females generally have higher-pitched calls than males.

Juvenile

Juvenile Australian crows resemble adults in their dark feather coloration yet are slightly smaller in size. Their eyes gradually change color from blue or grey in fledglings to the adult crow's characteristic white as they mature.

Size

16.9 - 21.3 in/9.9 - 28.9 oz

Habitat

Primary habitat

The Australian crow primarily inhabits woodlands, forests, and suburban areas throughout Australia.

Additional range

Unexpectedly, it’s also found in drier areas like deserts, adapting well to various climates from tropical to temperate.

What do Australian crows like to eat?

Natural diet

Australian crows have an omnivorous diet. They consume a variety of foods including insects, small animals, fruits, seeds, and carrion. They are known for their adaptability and can eat almost anything available in their environment, including roadkill or leftovers from other animals.

Bird feeders

While crows are not common visitors to typical bird feeders, they may occasionally be attracted to those offering larger food items. Crows may eat suet, peanuts, or sunflower seeds if easily accessible. Their preference for more substantial food means they are less frequent at feeders designed for smaller birds.

Chihuahuan Raven

Corvus cryptoleucus

Also known as: White-Necked Raven

How to recognise a Chihuahuan raven?

General appearance

The Chihuahuan raven is a bird that resembles the common raven but is slightly smaller in size, measuring between 19-21 inches or 48-53 cm. It has a smaller bill and a distinct voice. Its coloration is black and white. The wings of this raven are fingered and long while its tail is wedge-shaped. Its usual habitat is open grassland contrasting common ravens found in mountains or dry cactus deserts.

Male vs female

The Chihuahuan raven exhibits sexual monomorphism, meaning males and females have similar appearances. There is no significant difference in size, coloration, or body shape between males and females. Identifying the gender based on physical traits is challenging for this species.

Juvenile

Juvenile Chihuahuan ravens resemble adults but may have slightly lighter coloration. Their beaks may also be less robust, and they might lack the full fingered wing and wedge-shaped tail characteristic of adults. As they mature, they develop the distinctive adult features.

Size

18.1 - 20.9 in/13.4 - 23.6 oz

Habitat

Primary habitat

The Chihuahuan raven primarily inhabits arid and semi-arid grasslands, scrub, and yucca flats, mostly avoiding wooded areas and true deserts.

Additional range

This raven is also found in brushy lowland areas. However, unlike the Common Raven, it is rarely found in grasslands.

What do Chihuahuan ravens like to eat?

Natural diet

The Chihuahuan raven is omnivorous, with a diet predominantly consisting of animal matter. It consumes large insects, spiders, earthworms, snails, rodents, lizards, and the eggs and young of other birds. It is also known to eat carrion and garbage. Additionally, the raven feeds on various plant-based foods, including grains, seeds, berries, fruits, and cactus fruit.

Bird feeders

Chihuahuan ravens may occasionally visit bird feeders, particularly those offering seeds, grains, or fruit. However, they primarily rely on their natural food sources in the wild.

What does a Chihuahuan raven sound like?

The Chihuahuan raven has a harsh, raucous vocalization, characterized by high-pitched kraak sounds, distinguishably higher than those typically made by the Common Raven. Its call pattern is simple and flat, mostly resonating croak or quack like sounds rather than complex melodies or tones. The overall sound quality of its calls is striking and conspicuous.

How to tell the Australian Crow from the Chihuahuan Raven

Visual differences

The Australian Crow is robust, with a weight between 10-29 oz and a length of 17-21 inches. It has glossy black plumage, rare white patches, bright white eyes, and a stout beak. The Chihuahuan Raven, at 13-24 oz and 19-21 inches, is slightly smaller with black-and-white coloration, a wedge-shaped tail, and a smaller bill. Unlike the crow's bright eyes, it has dark eyes. Both species exhibit sexual monomorphism, making gender identification by appearance difficult. The Chihuahuan Raven often has fingered wings, unlike the smooth-edged wings of the crow.

Key differences and behavior

Australian Crows and Chihuahuan Ravens, both corvids, exhibit distinct behavioral traits. Australian Crows are adaptable, residing in varied climates, from woodlands to deserts. Conversely, Chihuahuan Ravens prefer arid grasslands, avoiding wooded areas. Crows are monogamous, forming lifelong bonds with elaborate courtship rituals, whereas Ravens might form loose colonies, suggesting social interactions during breeding. Crows are both opportunistic scavengers and omnivores, consuming anything from insects to carrion and occasional feeder visits. In contrast, Ravens' diets are more animal-focused, including insects, rodents, and bird eggs, with some plant consumption. Both species show little sexual dimorphism, but crows engage more in communal chick-rearing, with both parents defending fiercely. Ravens are resourceful, nesting in human-made structures, sometimes reusing nests, highlighting their adaptability within their preferred habitats.
