The Hawaiian Crow, Corvus hawaiiensis, also known as ´Alala to the Native Hawaiians, is a species of bird about the size (48-50 cm in length) of the Carrion Crow but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage, with long, bristly throat feathers; the feet, legs and bill are black.

Distribution and habitat

The species is now extinct in the wild. Prior to this, the species was only found on the island of Hawai‘i in open park-like montane forest. However, fossil remains indicate that it previously occurred in relative abundance on all the main islands, along with two other extinct crow species. The species is known for strong flying ability and resourcefulness, and the reasons for its extinction are not fully understood. It is thought that introduced disease was probably a significant factor in the species' decline. The Island of HawaiÊ»i (called the Big Island or HawaiÊ»i proper) is one of eight main islands that make up the U.S. state of HawaiÊ»i. ...

Behaviour

Diet

In the wild, Hawaiian Crows consumed a varied diet, including carrion, eggs and nestlings, other small creatures, fruits, and even human food and scraps. The birds were also known to pry bark off trees to uncover the insects beneath.

Nesting

The birds always nest in trees, with both males and females participating in nest construction. Nests in the wild were typically located in open woodland among a tangle of tree creepers, sometimes well away from other trees. Females generally lay five eggs; the eggs may be incubated by either parent, with the other bird usually sitting quietly near its brooding mate.

Voice

Hawaiian Crows have a call variously described as a two-toned caw and as a screech with lower tones added, similar to a cat's meow. They also make a ca-wak sound and a complex, burbling song, as well as various other sounds. Binomial name Felis catus Linnaeus, 1758 Synonyms Felis lybica invalid junior synonym The cat (or domestic cat, house cat) is a small carnivorous mammal. ...

Conservation status

The last two known wild individuals of this species disappeared in 2002; the species is now classified as Extinct in the Wild. While some individuals remain in captive breeding facilities, attempts to reintroduce captive-bred birds into the wild have been hampered by predation by the Hawaiian hawk or io, which is itself listed as endangered. The small number of living individuals may mean that the gene pool has been reduced to the point that the species can no longer recover. For album titles with the same name, see 2002 (album). ... Binomial name Buteo solitarius (Peale, 1848) The Hawaiian Hawk or Io, Buteo solitarius, is an accipiter of the buteo genus native to Hawaii. ...
