Baya Weaver: Nature’s master engineer of artistic hanging nests (photos)

KATHMANDU: The baya weaver, popularly known as the “engineer” among birds, is a fascinating and highly skilled nest builder belonging to the sparrow family.

In different parts of Nepal, the bird is known by various local names. In Dhading, it is commonly called “Tolayun,” while some regions refer to it as “Sujero” or “Bakecho.” In the eastern Terai, the same bird is popularly known as “Chonchi.”

Known for living in groups, baya weavers usually build their hanging nests on tall trees, bamboo groves, or near water bodies.

Their intricately woven nests, crafted from grass, leaves and fine plant fibers, appear like masterpieces of natural architecture and are considered one of nature’s finest artistic creations.

Primarily herbivorous in nature, baya weavers feed mainly on paddy grains and small seeds.

They are commonly found around farmlands and ponds, while insects and grasshoppers form only a minor part of their diet.

Male and female baya weavers can be distinguished by their appearance.

During the breeding season, the male develops a bright yellow coloration around its head and neck, making it more attractive, while the female has comparatively duller and lighter feathers.

One of the most remarkable traits of the baya weaver is that the male alone constructs the elaborate hanging nest. To attract a mate, the male works tirelessly to weave a beautiful nest.

The female carefully inspects the structure and chooses the one she prefers before laying eggs inside it.

If the nest fails to impress her, the male begins building another one, continuing the effort until the bird succeeds in winning a partner.
