Genus

Members of the genus Accipiter are small and medium-sized hawks, often called Sparrow-hawks or Goshawks. The females are almost invariably much larger than the males – in some cases weighing twice as much – a level of size dimorphism only exceptionally reached in any other genus Falconiformes. Their wings are short and rounded; the tail usually quite long. They are well adapted for flying through dense bush. Bird-catching Sparrow-hawks generally have long and slender legs, with slender digits, the middle one being especially long. Goshawks are usually larger, with shorter, thicker tarsi and digits and a shorter middle digit. Some smaller species have goshawk-like feet and vice versa, making it difficult on a world-wide basis to subdivide the genus on this or any other broad basis. Although many accipiters feed upon birds moreso than do other hawks, some species take many mammals, especially squirrels; others take lizards, frogs, snakes, insects, even snails. In these species the legs and digits are sometimes slender, but short. Accipiters are rarely crested, but some have very attractive colour patterns. Black phases are present, especially in the tropical species. One in Australia has the only pure white phase. Accipiter is the largest genus in the family, having about fifty species. It is present worldwide, but is especially rich in Papua-New Guinea, where a small island like New Britain may have three to five endemic species or distinct sub-species.

Physical charateristics

Adults are slate gray above and white below with heavy black barring. Immatures are either brown or rufous. Similar to the Tiny Hawk (A. superciliosus) of lower elevations, the Semicollared is unique in having a pale nuchal collar and generally a pale, streaked cheek giving it something of a hooded appearance.

Conservation

This species has a small population but there is currently no evidence that it is declining so it is consequently classified as Near Threatened. Evidence of declines may result in its uplisting to Vulnerable.
Forest in many parts of its range has suffered major losses, primarily due to agricultural expansion. The photo is copyright of http://www.proaves.org – “Saving birds and biodiversity in Colombia, forever”.
