A nest is a place of refuge built to hold an animal's eggs and/or provide a place to raise their offspring. In most Birds and Reptiles an egg ( Latin ovum) is the Zygote, resulting from Fertilization of the Ovum. They are usually made of some organic material such as twigs, grass, and leaves; or may simply be a depression in the ground, or a hole in a tree, rock or building. Life is a state that distinguishes Organisms from non-living objects such as non-life and dead organisms being manifested by growth through Metabolism A twig is a small terminal Branch section that may bear leaves, Buds and sometimes the Flowers and Fruit of Plants Only Grass is the common word that generally describes Monocotyledonous green Plants The family Gramineae ( Poaceae) are the "true grasses" and include In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. Human-made materials, such as string, plastic, cloth, hair or paper, may be used.
Generally each species has a distinctive style of nest. Nests can be found in many different habitats. A habitat (which is Latin for "it inhabits" is an Ecological or environmental area that is inhabited by a particular Species.
Nests are built primarily by birds, but also by mammals, fish, insects and reptiles. Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands Fish are aquatic Vertebrate animals that are typically ectothermic (previously Cold-blooded) covered with scales, and equipped with two Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers
They may have some or all of the following zones: attachment; outer decorative layer; structural layer; lining.
Some birds will build nests in trees, some (such as vultures, eagles, and many seabirds like Kittiwakes) will build them on rocky ledges, and others nest on the ground or in burrows. Vultures are scavenging Birds feeding mostly on the carcasses of dead Animals Vultures are found on every continent except Antarctica and Eagles are large birds of prey which are members of the Bird order Falconiformes and family Accipitridae, and belong to several genera Seabirds are Birds that have adapted to life within the marine environment The kittiwakes ( Genus Rissa) are two closely related Seabird species in the Gull family Laridae the Black-legged Kittiwake

Most species of birds build some sort of nest, though some lay their eggs directly onto rock ledges or bare soil without first modifying the area. The Blue Jay ( Cyanocitta cristata) is a Passerine bird and a member of the family Corvidae native to North America. A bird nest is the spot in which a Bird lays and incubates its eggs and raises its young Nest types vary from the very simple scrape, which is merely a shallow depression in soil or vegetation, to the elaborately woven pendant or sphere; some bird species use cavities in trees or dig burrows into the ground.
