Nest

Bald eagles build the largest tree nests of any bird. They can weigh 2 tonnes (4,400 lb).

The Long-tailed Tit uses moss and the silk of spider egg cocoons as a natural form of Velcro for holding its nest together.

Hummingbirds gather spider silk to bind their nests together. They wrap these silk threads around other materials they collect, such as moss and lichen, to create not only a soft and durable but stretchable nest to accommodate the birds' growing nestlings.

Birds that live in cities have learned to line their nests with cigarette butts. Nicotine is a powerful insecticide that wards off mites, lice and fleas.

Termite nests can be nearly 7 m (23 ft) tall.

The Oecophylla smaragdina species of arboreal ant make nests made of leaves stitched together using the silk produced by their larvae.

King Cobra females are the only snakes that build nests.

The nests that Chimpanzees make for themselves on tree tops are much cleaner, containing fewer microbes and parasites, compared to human beds.
