Hornbeak, broad-beaked (Eurylaimidae), bird family ref. passerine suborder screaming (Oscines). Length 7-28 cm, weight 20-150 g. The head is large, the eyes are large. The beak is short, flattened, often hooked, with a wide slit in the mouth (hence the second name). The wings are short, rounded; the tail is short, rounded, or long, stepped. The color, as a rule, is bright, green, blue, crimson, yellow tones in combination with velvet black prevail. The beak and unfeathered areas around the eyes are often painted in bright colors. 11 genera, 18 species. Inhabitants of humid tropics. forests of Africa, South. and South-East. Asia, few are associated with forest edges or thickets of shrubs. They feed on insects, large species also feed on small vertebrates, in some small fruits predominate in the diet. They are inactive during the day, feed in the morning. During mating games, the male demonstrates bright plumage, periodically makes short circular flights (while the feathers emit vibrating sounds). Both parents build a nest, incubate eggs (usually 1–3) and feed the chicks. Nests are elongated, hanging, with a side entrance, sometimes with a peak above it. The inhabitants of Madagascar - 4 species from the genera Philepitta and Neodrepanis - once stood out as independent species. this Philepittidae. In their food means. the share is nectar, the beak of pseudo-nectarians, unlike other R., is long, thin, sickle-curved. 3 species - in the IUCN Red List.


Horn-billed (lat.Eurylaimidae) or wide-billed - a family of birds from the order Passeriformes, separated into a separate suborder. It is divided into eight genera and fourteen species. Hornbills live in tropical forests and forest regions of Africa, South and Southeast Asia. Their size ranges from 14 to 28 cm. They are small birds with a strong, thick beak, short legs and tail. Most species have a rounded tail. The only exception is the long-tailed broad-beak (Psarisomus dalhousiae). They tend to have variegated plumage, and there are differences in appearance between the sexes. The food mainly consists of fruits, seeds, insects and other invertebrates. Horn-billed nests are shaped like a pear and hang above the water, attached to tree branches. Unlike other passerines, which have 14 cervical vertebrae, the hornbills have 15 of them. In addition, they have unique [what kind?] tendons on the paws.


Hornbeaks - clade of small passerine birds, Eurylaimidae (named after the genus type Eurylaimus). Varieties Smithornis and Pseudocalyptomena occur in sub-Saharan Africa, the rest extend from the eastern Himalayas to Indonesia and the Philippines.

The family possibly also includes the sapayoa from the Neotropics and the asities from Madagascar, although many taxonomists now divide each of the three into distinct families.


Many hornbeaks are brightly colored with birds that feature broad heads, large eyes, and a hooked, flat and wide beak. They range from 13 to 28 centimeters in length, and live in dense canopies of humid forests, allowing them to hide despite their brightly colored plumage. The plumage of adolescent eurylaimids is similar to those of adults, differing in being duller and with shorter wings and a shorter tail in some cases.

Behavior and ecology

Hornbeaks are mostly insectivorous and carnivorous. Prey taken includes insects, spiders, millipedes and millipedes, as well as lizards and tree frogs. The prey is obtained sallying from height to grab it in flight and picking prey from leaves and branches while flying. Some varieties can take some fruits, but only green hornbeaks of the genus that Calyptomena and Groer's hornbeak are primarily frugivores (which also take on some insects as well).

They are generally sociable with many species, moving in flocks of about 20 people. Hornbeaks attach their purse-shaped nests to suspended vines and leave a tail of fibers hanging below it. This gives the nest the appearance of being random debris caught in the tree, an effect further enhanced by birds covering the nest with lichen and cobwebs. Hornbeaks usually lay two to three eggs.

Taxonomy and taxonomy

sapayoa was originally classified in the Pipridae group, according to at least one author, the genus more accurately now offers its own family. Four species of asities, a family native to Madagascar, are sometimes included in the hornbeak. It has been suggested that the group should not be monophyletic.

Great Green Buckbeak / Calyptomena whiteheadi

Lesser green hornbeak or green calyptomene is a South Asian songbird of the hornbeak family.

Small green hornbeak 20 cm long. The bird has a large tufted head and a short tail. The broad beak is covered with feathers at the base. The plumage of the male has a green color, three black stripes on the wings and a small black spot on each side of the neck. Females have less bright plumage.

The Lesser Green Rollbeak is native to Southeast Asia from Thailand to Papua New Guinea. He lives in tropical and subtropical forests. In small flocks, the bird searches for its food in the lower canopy of the forest. It feeds mainly on fruits such as figs.

In a pear-shaped nest of intertwined plant fibers, which hangs on the lower branch, both parent birds incubate a clutch of one or three eggs.
