Cotinga

life science Maturity 7-9 Next article →

The cotingas are a diverse family of birds known scientifically as Cotingidae.

These suboscine passerine birds live throughout Central America and tropical South America. They occupy various environments, including humid tropical forests, forest edges, coastal mangroves, and even open woodlands or deserts. Most cotingas are primary frugivores, meaning their diet consists mainly of fruit.

Physically, they are characterized by broad bills with hooked tips, rounded wings, and strong legs. Their sizes vary significantly across the family. The tiny fiery-throated fruiteater represents one end of the scale. The large Amazonian umbrellabird represents the other.

Social structures and parental care vary widely among these species. The family is split roughly in half regarding how they raise their young. In one group, species practice biparental care, where both parents help raise the offspring. In the other group, males play no part in raising the young. Some species, like the purple-throated fruitcrow, live in mixed-sex groups.

In these specific groups, one female lays an egg. The other females in the group assist by providing insects to the chick.

In species where only females care for eggs and young, males engage in intense courtship. This process is driven by sexual selection, where certain traits help a male attract a mate. Many of these males gather in groups called leks to perform displays.

Some genera, such as Carpodectes, Cotinga, and Xipholena, are canopy-dwelling. In these groups, males gather in a single high tree or in nearby trees. Other species, like the cock-of-the-rock, are more terrestrial. These males perform their elaborate displays in leks located on the ground. This selection often results in males having bright colors, long plumes, or fleshy throat wattles.

Some species, like bellbirds and the screaming piha, rely on distinctive, far-carrying calls.

Nesting habits are as diverse as the birds themselves. Nests can range from very large to extremely small. Some species lay a single egg in a nest so flimsy that the egg is visible from underneath. This structure may help hide the nest from predators.

Other birds, such as fruiteaters, build more solid cup nests. The Guianan cock-of-the-rock takes a different approach by attaching mud nests to cliffs. Most nests are either open cups or small platforms made of loosely woven plant material. These are usually placed within trees. A typical clutch contains between one and four eggs. Incubation generally lasts 15 to 28 days. Once hatched, the fledglings usually leave the nest within 28 to 33 days.

The history of cotinga classification involves many scientific discoveries. The family Cotingidae was introduced by the French naturalist Charles Lucien Bonaparte in 1849.

As of July 2021, the International Ornithological Committee recognized 66 species within 24 genera. Modern science uses molecular phylogenetics to understand their relationships. A 2014 study by Jacob Berv and Richard Prum examined the DNA of cotingas. They found that the genera form five monophyletic clades. Based on this, they proposed the family could be divided into five subfamilies. Other studies, such as one by Michael Harvey in 2020, have further mapped the suboscine tree. One specific finding showed the genus Tijuca is embedded within Lipaugus.

Cotingas are currently facing significant biological and environmental challenges. Their survival is closely tied to the health of their specific habitats. Because they rely so heavily on forest environments, the loss of these habitats poses a very serious threat.

Understanding their complex social systems and nesting requirements is vital for conservation. As forests change, the delicate balance of their feeding and breeding cycles may be disrupted. Protecting the diverse ecosystems of Central and South America is essential for the continued existence of these unique birds.
