The humble baya has the ability to construct some of the most elaborate nests in the entire animal kingdom.

The baya, also known as the baya weaver, is a small songbird that takes up residence in huge nests it has constructed for the breeding season. Their homes are composed of an entrance and chamber in which they can raise a successful brood. The name of the baya comes from the local Hindi name for the species. It is just one of many different types of weaver birds.

3 Baya Amazing Facts

  • Baya weavers were sometimes trained by people in India to perform tricks for public entertainment. They could supposedly play with toys and pick up coins and other objects.
  • One popular myth is that the baya would use fireflies to light up the inside of their nest.
  • Another popular myth is that the baya will die when its mate dies, but this doesn’t appear to be based on fact at all.

Where to Find the Baya

The baya weaver is found in grasslands, scrubs, agricultural fields, and secondary growth forests throughout South Asia and parts of the Pacific region. They are particularly prolific across the entire subcontinent of India.

Baya Nests

Baya weavers construct highly elaborate nests from grass stems and other plant fibers. Unlike many other types of birds, these nests are constructed solely by the male. They resemble a large upside down flask or gourd with a large central chamber and a long vertical tube that leads out to a side entrance. Nests are built on thorny acacia or palm trees overhanging the water for protection.

Baya Scientific Name

The scientific name of the baya weaver is Ploceus philippinus. The genus name Ploceus means weaver. It is derived from the Greek pleko, meaning “to entwine.” The species name Philippinus is derived from the Philippines, even though it this is actually a huge misnomer. The original scientific discoverer mistakenly believed that his specimens had come from the Philippines, but it isn’t actually found in the country at all. The baya belongs to the weaver genus, which includes some 57 closely related species. Five distinct subspecies of the baya are recognized by taxonomists.

Baya Size, Appearance, and Behavior

The baya is a small songbird, measuring about 6 inches long and a 10 inch wingspan, with a stout bill and a square tail. Non-breeding males and females have a cream-colored body with brown or black streaks on the wings. A yellowish hue is also mixed in throughout the entire plumage. When the breeding season arrives, the males start to grow bright yellow breast and crown feathers with a dark brown facial mask. Juveniles look similar to females, but they lack the same thick eyebrows. Regional variations also exist in the precise arrangement of colors throughout the plumage.

The baya weaver is among the most “gregarious” (meaning social) birds in the world. They form large colonies of about 20 to 30 birds in which they construct their nests for the breeding season. These flocks forage for food together and fly in formation when the need arises. They also spend a lot of time throughout the day dust bathing and preening. Their calls can be generally divided into mating songs, alarm calls, chick cries, and other communication calls.

Baya Migration Pattern and Timing

The baya makes seasonal movements every year in response to rain and the availability of food, but they tend not to travel very far from their initial home.

Baya Diet

The baya is an omnivorous bird that likes to forage on trees and the ground in large groups.

What does the baya eat?

The diet of the baya weaver consists almost entirely of seeds and grains. The large beak is well-adapted for cracking open the thick shells with incredible ease. Because they often raid rice fields, the bayas are sometimes viewed as a pest by humans. They will also sometimes supplement their diet with insects, frogs, and other small animals.

Baya Predators, Threats, and Conservation Status

According to the IUCN Redlist, the baya is considered to be a species of least concern. They do face some challenges from habitat loss, but overall this species is very common and widespread through South Asia, and they have adapted well from the transformation of their habitat into farmland.

What eats the baya?

The baya is preyed upon by numerous types of snakes, lizards, crows, and birds of prey. The eggs and chicks are particularly vulnerable to predation, but the location of the nest, suspended from a thorny tree above a source of water, usually provides a degree of protection against most predators.

Baya Reproduction, Young, and Molting

When the breeding season arrives between April and August with the coming monsoons, males in the flock gather together and make a series of alternating chatters and whistles to attract a potential mate. At the same time they hang upside down while fluttering their wings. Males will start to construct the nest early in the breeding season, but it will remain uncompleted until the male succeeds in attracting its first partner.

After mating, the female lays two to four white eggs per clutch. Together the parents incubate the eggs for 14 to 17 days before they hatch. The chicks rely on the mother and sometimes even the father to feed them. It takes about 17 days before they leave the nest for the first time. They gain their full adult plumage after four to six months, but it can take at least a year before the chicks reach full sexual maturity.

Both males and females are polygamous. This means that they will continue to mate with other partners even after raising their first successful brood to completion. Females are also known to lay their eggs in the nest of other baya weavers to take advantage of their parental instincts. The typical lifespan is not well-known, but many weavers can live at least 10 to 15 years old.

Baya Population

The global population of the baya has never been properly estimated, but the IUCN Red List considers the population to be stable and unchanging.
