The whistling warbler ( Catharopeza bishopi ) is a small songbird and the only representative of the genus Catharopeza from the family of the wood warbler (Parulidae). It is closely related to the species of the tree warbler ( Setophaga ). Some authors also consider the whistled wood warbler to be a different species of the genus Setophaga . The distribution area is on the island of St. Vincent of the island state of St. Vincent and the Grenadines of the Lesser Antilles . It was discovered in 1877 on the Soufrière volcano . The IUCN has listed the species as "endangered" since 2000.
features
Pfeifwaldsänger reach a body length of 14.5 centimeters and a weight of 16 to 19 grams. The wing length is about 7 centimeters in the male and about 6.68 centimeters in the female. Adult males have black head and throat plumage, grayish-blackish upper side plumage and a concise, wide, white eye ring. The underside plumage is dirty-white, the flanks and the chest band are blackish-gray. The under tail-coverts are gray with white feather tips. The beak is black, the legs pink-flesh-colored.
Juvenile specimens in the first year have a dark olive-brown head and upper side plumage as well as a cinnamon-brown to yellow-brown lower side plumage with a dark olive-yellow-brown chest band. The white eye ring is narrower than in adults.
Habitat, Nutrition and Reproduction
Whistling warblers occur in primary rainforests, moist secondary forests, on forest edges and in dense palm undergrowth. They feed mainly on insects . They hop slowly from branch to branch, peck their prey hanging upside down from the underside of the leaves or lurk like flycatchers for insects flying by.
Your cup-shaped nest is built in the lower vegetation . The breeding season takes place between April and July. A clutch usually consists of two eggs. There are no precise studies of the incubation and nestling times. Begging young birds were spotted in June, July and early August.
Hazard status and inventory figures
The IUCN lists the whistled warbler as "endangered" because of habitat destruction. By 1986 the suitable habitat had decreased from 140 km² to around 80 km². Large parts of the habitat were twice destroyed by eruptions of the Soufrière volcano. However, the birds returned after vegetative regeneration. In 1973 1,500 brooding individuals were counted and in 1986 1,500 to 2,500 singing males. BirdLife International estimates the population size to be 3000 to 5000 individuals.
