Nest build fresh nests daily out of leaves and other vegetation in which they sleep at night. They sometimes also build nests during the day for resting in. The smaller species of gorilla build their nests in trees, while the larger are confined to the ground. Nests of the western gorilla, the largest species, measure about in diameter. Some species of frog build nests ranging from simple to modest complexity. Many stream-dwelling frogs lay their eggs in a gelatinous mass which they attach to underwater vegetation. The jelly structure prevents the eggs from washing away. Fish engage in nest building activities
The Mammal Society Handbook is well established as the classic reference source detailing the biology, ecology and conservation of every mammal occurring in Britain and Ireland. The 3rd edition, dating to 1991, had long been out of press, until over 100 of the leading mammalogists, mostly members of The Mammal Society, contributed to complete this comprehensive 800-page 4th revision, published in 2008.
