Nesting: zhùchaǒ Most birds during the breeding season, in their nesting areas within _select_ed plant fibers, twigs, leaves, weeds, dirt, animal hair or other objects Toba, built into bird eggs can roll without bulk, and can even be simultaneously birds body temperature incubation and feeding young in favor of the parent birds nest, called nesting. However, there are no hatchery nesting birds such as puffins, king penguins, etc.; also some birds nest neither nor hatchery, such as azaleas. In addition, there are nesting behavior of fish, such as mullet, salmon, tilapia and tropical fish. Amphibians Emei frog (rhacophoru someimontis), breeding mucus in the treetops with leaves rolled into small tube will nest and lay their eggs in the nest barrel. Although no reptiles crocodile hatchery, but good at breeding nest with grass barricaded. Such as alligators in spawning before digging in the ground about half a meter in diameter shallow pit, pit stacking to 20 to 30 cm thick weeds and leaves and other things, when the birth of 16 to 47 eggs, and then cover about 0.5 m thick weeds, built into a pyramid big haystacks, the use of weed-corruption after the release of thermal energy eggs hatch. Observation of birds nesting behavior After accounting for bird area, courtship display and form a spouse, you immediately enter the nervous nesting phase. Most birds are nesting in the spring, until the chicks hatched, happens to be the largest number of natural reproduction within the insect when it was nestling growth and development provides a rich food. Birds nest-site _select_ion and each bird is closely related to lifestyle and feeding sites. If the forest birds, some of the nests built in tree canopy portion; others built in the bush or ground grass; There is a crevice or nest in tree holes. No matter where birds nest, the basic conditions are the food is plentiful, well-lit, there is a good hidden conditions. Different birds, nesting behavior varies. There are many types of gender work together to help look for nest material, work together to build the nest, like many seabirds, most woodpeckers, swallows, sparrows shrike and so on. Although some species of male and female co-nesting, but there is a clear division of labor, male hunts drawn, the title back to the female after compilation, such as many herons. Some species only by the male or the female alone made nest. Variety of birds nesting material. The most common nest material has branches, leaves, stem, fibers, feathers, dirt, moss, etc. Most passerine species, mainly woven nest of twigs and grass stems; swifts and swallows nest timber with soil-based; chicken nest material mainly grass; turtle nests are barricaded with litter The; while woodpeckers usually in a cave bedding layer of broken wood. Different birds, their nesting location and shape of the nest there is specificity. Chicken, geese and ducks, gulls and some passerine bird nest on the ground; some waterfowl can be broken on the water use measures such as reeds or grass stems floating nest discoid; woodpeckers and other needs in the trunk borehole for the nest, tits and other small birds in the natural tree holes or rock crevices nest; while most birds in a tree is constructed using the decentralized branches nest. Some nest Dazao was very simple, while others are very particular. From the shape of the nest can be divided into the nest bowl, cup nest, globular nest, nests, etc. pouch. For the vast majority of birds, the nest is not their "home", diurnal birds flew mostly at night in the woods or thickets to sleep sitting on the branch, ducks and other waterfowl habitat in the lake often a safe place. Birds in the spring by building their nest eggs and brood only temporary "housing." Birds lay their eggs in the nest, can focus on an egg roll without bulk, and can also accept the birds body temperature incubation. In addition, in the nest of eggs or chicks, under the protection of the parent birds to avoid predators damage. Birds nesting activity, it is often difficult to completely observe clear because in making birds nest stage, activity becomes very subtle, vigilance is also high, they no longer sing, but cautious manner, "construction", once subject to greater interference, it will abandon the nest and the alternative is to build a new site.

Nesting: Zhùchaǒ Since the nest with some slow heat loss insulation effect is conducive to growth and development of chicks. Reproductive success of birds nesting is an important part. Nesting sites varies by species, some nests built in the shelter, and to camouflage; others built on the cliff; others built on tall slender twigs among the treetops; also some built in the ground, water, caves or buildings material inside. Most nesting birds by a female bear, there are male and female birds nest collaboration. Nesting behavior of the active process that helps stimulating physical activity, so that the body of the egg cell maturation and discharged rapidly, without disrupting the breeding behavior. Amphibians Emei frog (Rhacophoru someimontis), breeding mucus in the treetops with leaves rolled into small tube will nest and lay their eggs in the nest barrel.
