features
The great-billed crow is a medium-sized, short-tailed crow with a light, massive beak that has a dark tip. It reaches a size of 40 to 41 cm. The males weigh approximately 615 grams, the females 555 to 568 grams. The ridge of the beak is strongly curved. The nasal bristles are divided on the forehead. The feathers on the neck and head are thin and silky. The plumage is completely black with a slight green sheen. The iris is brown or gray to dull blue-white. The beak is ivory with a black tip. On the sides of the chin, between the halves of the beak, there is a pink-red, featherless area of skin. The legs are black, the soles orange. The sexes are similar in plumage, but the males are larger than the females. The young birds have not yet been described. The call consists of staccato-like, shrill croak tones that are faster than the Salvadoran crow ( Corvus orru ).
distribution and habitat
The distribution area extends to the Solomon Islands Choiseul , Guadalcanal and Santa Isabel . The great-billed crow lives in lowland or mountain rainforests at altitudes of up to 1000 m, rarely up to 1250 m. It is most widespread on the hills. It can often be observed in the interior of the forest or at the edges of the forest. Sometimes she forages near coconut plantations.
Way of life
The great-billed crow is an omnivore. The diet consists of insects (mainly beetles) and fruits. It goes in search of food individually, in pairs or in small groups in the canopy. The breeding season probably takes place in the southern spring. The great-billed crow is a local bird.
status
The IUCN classifies the species in the category “not endangered” ( least concern ). It has so far been little researched. It's quite common locally.
