True weavers have the amazing ability to build complex nests in the breeding season.

The weaver is a family of songbirds originating from Africa and Asia. While not all members of this family are technically called weavers, most of them do construct elaborate nests and breed together in sizable colonies. These nests are some of the most amazing constructions in the entire bird world. There are many different types weavers, each with their own unique nests.

3 Weaver Amazing Facts

• Weavers are said to be very smart birds that can trained to perform tricks and stunts.
• Weavers have the ability to hang upside down from just about any surface or object they can cling to with their talons.
• Some species are dedicated “social parasites” that lay their eggs in the nest of another weaver species. The new parents are then tricked into raising the chick as their own.

Where to Find the Weaver

Weavers are endemic to grasslands, forests, and savannas throughout sub-Saharan Africa and South Asia. A few species have been introduced outside of their original range as well.

Weaver Nests

The one quality that unites together all weavers is their ability to construct big nests from grass, leaves, and other plant fibers. These nests can range from simpler roofed habitat to a complex cylindrical structure comprised of a single tube-shaped entrance and an internal chamber. Suspended from a thorny palm or acacia tree over a body of water, the nest is constructed by the male in the breeding season with only his feet and beak to work with. Weaver nests vary in both their size and shape. The social weavers of southwestern Africa construct giant communal nests that reach a height of around 10 feet.

Weaver Scientific Name

The scientific name for the weaver family is Ploceidae. It is derived from the ancient Greek word plokeus, meaning weaver. The family also includes bishops, widowbirds, and queleas, but weavers make up the bulk of the species. The genus Ploceus is the most populous with some 60 or so species alone.

Weaver Size, Appearance, and Behavior

Weavers come in a remarkable variety of different shapes and colors. These are small songbirds, rarely measuring much more than 5 to 10 inches from their rounded head to square tail. The plumage is perhaps the most interesting and diverse characteristic. Bright red, yellow, black, gray, brown, and white, arranged in different patterns and shape, are all very common plumage colors. The male weavers from the genus Ploceus are particularly notable for their ability to grow bright yellow plumage in the breeding season.

Weavers are among the most gregarious (meaning social) birds in the world. They often nest together in large colonies that consist of dozens of members at a time. The red-billed quelea is particularly extraordinary in this regard; it has been seen occupying massive colonies over many square miles in which millions of birds are supposedly said to reside. Weaver birds do almost everything in close proximity to each other, including foraging, breeding, and preening. When they travel together, some species also fly in a tight formation. Their high-pitched chattering calls include mating songs, alarm calls, and chick cries.

Weaver Migration Pattern and Timing

Weaver birds generally don’t migrate far, but many types of species do travel seasonally in response to changing weather and food availability. They generally migrate together as a large flock.

Weaver Diet

The weaver is an omnivorous bird that spends much of its day foraging on the ground and trees.

What does the weaver eat?

The diet of the weaver mostly consists of seeds, grains, insects, and other small animals. Their large beak enables them to crack open the thick shells on which they feed. Because of their habit of raiding farmlands and fields, some weavers are considered to be annoying agricultural pests.

Weaver Predators, Threats, and Conservation Status

The weaver varies considerably in its conservation status. According to the IUCN Redlist, the majority of species are considered to be least concern, meaning they require no specific conservation effort. A few of them are endangered too, including Finn’s weaver and the golden-naped weaver. Habitat loss is a persistent threat for some species, but they can adapt fairly well to human presence.

What eats the weaver?

Many weavers are preyed upon by snakes, lizards, crows, and larger birds of prey. The location of the nest, suspended from a thorny tree over a body of water, can provide protection against predators. Mobs of weavers may also work together to drive the predator away.

Weaver Reproduction, Young, and Molting

The weaver bird has many different reproductive strategies. Many species gather together in large communal flocks to attract a mate. Males produce a chattering bird song while fluttering his wings. Females will judge the male by the quality of his nest, so not everyone will have immediate success. Many nests are abandoned without use in the breeding season (although this may also be an anti-predator strategy). After a few weeks of incubation inside the nest, the eggs will start to hatch. With rigorous feeding and care from the parents, the chicks will gain their flight feathers and start to leave the nest only a few weeks later. Both parents are generally polygamous, meaning they might have multiple mates per breeding season. The lifespan varies, but many of these birds live some 10 to 20 years long.

Weaver Population

Good population estimates are not available for the majority of species, but there are some exceptions. The vulnerable bannerman’s weaver has some 6,000 to 15,000 mature individuals remaining in the wild. The giant weaver has anywhere between 2,500 and 10,000 mature individuals remaining. The endangered Finn’s weaver has less than a thousand mature individuals remaining. Many other species are likely to have a similar population range.
