17 Amaze-wing Facts About The Brush Cuckoo For Kids

Brush cuckoo facts are sure to surprise you.

The brush cuckoo (Cacomantis variolosus) is a bird species that has a largely gray-brown head and tail plumage, and dark brown or dark gray wings, along with buff underparts. Both male and female brush cuckoos look nearly the same, but the female may have a smaller region of buff underparts. Buff, as you may already know, is a light brown to yellow ochre-ish color, which fits the description of the underparts of the brush cuckoo species. The brush cuckoo habitat range stretches across northern and eastern Australia, Papua New Guinea, the Solomon Islands, Indonesia, and Thailand.  They can be found in a wide variety of habitats including rainforests, rainforest edges, mangroves, and secondary forests. A Brush cuckoo's diet consists of a variety of caterpillars, beetles, ticks, and mites, as well as fruits, shoots, roots, and nuts. The breeding season for brush cuckoos is around the spring and the summer. The male and female pair find a site high on a branch for copulation.

The brush cuckoo (Cacomantis variolosus) is a brood parasite, like many other species of cuckoos. What this means is that adult female brush cuckoos will often lay eggs in the nests of other species of birds and rely on them to raise their juvenile cuckoos. Brush cuckoos have the ability to lay eggs specifically for a certain host that has markings almost identical to their eggs. They don't even build a nest of their own! Once the young cuckoos hatch, they either evict or take the upper hand from the juvenile host eating all their food and killing them. Cuckoos are barred from ever meeting their parents. The brush cuckoo call is considered one of the most melodious of all birds of the world, and several birdwatchers often travel long distances across northern Australia to hear the famous brush cuckoo song. The population of the brush cuckoo bird is stable, and its habitat range is not under any threat as of now.

The female lays eggs in the host bird's nest, and baby brush cuckoos are then raised by an entirely different species. Males can also help find hosts after breeding.
