Sociable Weaver

 

 

 

 

 

The sociable weaver, native to South Africa, Namibia and Botswana,

weaves huge communal nests that can hosts hundreds of birds across

multiple generations.

 

These nests, woven from sticks and grass, are permanent. The deeper

inner chambers maintain a higher temperature at night, allowing the

birds to stay warm.

Australian Weaver Ants

 

 

Weaver ants, which live in Central Africa and South-East Asia, pull together live leaves and use larval silk to glue them together. These nests can vary in size from a single leave to bunches of glued leaves up to half a meter in length.

Vogelkop Bowerbird

 

 

 

 

 

The male Vogelkop bowerbird creates bowers, or small huts, out of grass

and sticks to attract females to mate with. The consummate interior

designers of the animal world, these birds arrange berries, beetles,

flowers and other colorful and eye-catching ornaments into artistic

arrangements to attract their mates. Ironically, the females do not

actually use these bowers to raise their young.

Compass Termite

 

 

 

The compass termite builds large wedge-shaped mounds for nests.

These wedges are roughly oriented in a north-south orientation, which

gives them their name. It is believed that this shape helps their mounds

stay thermoregulated.

Honeybees

 

Honeybees’ entire lives revolve around their nests. It is in these nests, w

hich they construct out of secreted wax, that they process their food

and raise their young.

European Red Wood Ants

European red wood ants build large mounds on the forest floor to house

their nests. Several of these mounds can be linked as mother-daughter

mounds for the ants to switch between in the event of a catastrophic

event at one o the mounds.

Red Ovenbird

 

The red ovenbird builds its nest out of clay and mud. These strong

nests help prevent predation and, once abandoned, can provide other

birds with a relatively secure place to live.

Baya Weaver

 

 

 

Baya weavers often build their elegant hanging woven nests in thorny

palm and acacia trees or above bodies of water, where predators may

have difficulty reaching them. The nests can often be found in colonies,

although isolated ones do exist as well.

Wasp

 

The majority of wasps actually do not actually build nests, preferring

solitary or even parasitic arrangements. Social wasps, on the other

hand, build elegant paper nests out of plant pulp, spit, resin and other

materials.

 

These consist of internal paper honeycomb tiers (similar to a honey bee’s

comb in appearance but not material) surrounded by a paper wrapping.


Beavers

Beavers build damn to flood woodland areas to a certain depth. They

then build submerged entrances that allow them to avoid predators

and to hunt for food in the winter.

 

Their dams can be truly massive – the largest known beaver damn, in

Canada’s Wood Buffalo National Park, is roughly 850m, or 2790 ft,

in length. When the water is deep enough, they may sometimes live

in burrows instead.


Montezuma Oropendola

 

 

The Montezuma oropendola weaves its nests out of small vines and grass.

They usually live in colonies of roughly 30 birds, which include a dominant

male that mates with the females.


Swallow

 

 

 

Swallows build nests out of various materials, and some don’t even build

any at all, choosing instead to nest in found or abandoned cavities. Certain

species of swallow, however, create their nests primarily out of their own

saliva. These nests are edible, and are considered a delicacy by some.

Caddisfly

 

When it’s time for the caddisfly to pupate, it spins a tough cocoon out of

pebbles, sand, shells, and other lake- and river-bed detritus. It weaves t

hese elements together with strands of its own silk to safely grow to

adulthood.
