Identificazione

Rufous whistlers are large-headed and stocky. They have short beaks and long tails (almost as long as the rest of the bird) which are very narrow and have sharp, forked tips.The species is sexually dimorphic. While females are typically dull brown or grey with streaked underbodies, males have rufous underparts and predominantly dark-grey back and tail with white throats and (in most cases) a black mask that covers most of their head and some of their neck.These birds are between 16 and 18 centimetres (6.3 and 7.1 inches) in size, on average, and their normal weight is approximately 25 grams (0.88 ounces).<p>The rufous whistler has a variety of musical calls which consist of a lengthy series of ringing notes.

Tassonomia

The rufous whistler was originally described in the genus Sylvia by the English ornithologist John Latham in 1801. It was subsequently classified within the genera Turdus, Laniarius, and Lanius before being classified in its present genus, Pachycephala. Alternate names for the rufous whistler include the rufous-bellied whistler and white-bellied whistler. The latter name should not be confused with the species of the same name, Pachycephala leucogastra. Some authorities have considered the black-headed, drab, and cinnamon-breasted whistlers to be subspecies of the rufous whistler.<p>Five subspecies are recognized:

Areale e habitat

The rufous whistler can be found in forested areas, woodland, and shrubland, but also in gardens and farmland. It migrates seasonally, moving south in the spring and north in the autumn. In New Caledonia the species does not undertake migrations but is instead resident in areas of open forest and savannah.

Comportamento

Breeding in monogamous pairs, both males and females incubate their eggs and care for their young. The period of incubation is about 13 days on average. The female alone constructs the nest, which usually consists of a combination of twigs, vines, grass and other matter formed in a cup-like shape and attached to a tree branch using strands from spider webs.The breeding season for rufous whistlers is between the months of July and February.<p>While rufous whistlers primarily feed on insects, they also eat seeds, fruit and occasionally, leaves and grasses. They never forage for food on the ground which is unusual for whistlers which typically do not forage at particularly high levels.
