NestingMallards usually nest on the ground, often in dense undergrowth beside lakes and streams. They will also nest in holes in trees, sometimes well above ground level. Between March and May the female lays between eight and fourteen eggs in a nest of grass, and sedge lined with fine down.
Reed warblers
The male and female are almost identical, and their nests are usually
suspended between reed stems.
The baby owls, called owlets, are grey downy creatures with big round faces and dark eyes like those of their parents

Nests are Built for the Eggs

The song thrush, one of a number of cup-nest builders, uses mud as an integral part of the nest structure. One of the characteristic features of this nest is that mud forms not only an important structural component but the inner lining of the nest as well.

Baltimore Oriole Nest
Like many birds, the Baltimore oriole uses the materials it finds closest at hand to build its saclike nest. The nest pictured here is made mostly of cattle hair and string, commonplace items on the farmland it frequents

Brush Turkey
The female does most of the incubation, while the male brings in the food. Their two to four eggs hatch usually in May, when the male will usually pass prey to the female who then feeds the young at the nest.
The fastest running bird is
the ostrich, but it cannot fly. The
ostrich is also the fastest two-legged runner of all the
animals on Earth. The ostrich is the
largest bird.

These lovely birds are fond of cliffs and boulder-strewn islands with grassy slopes, and in the western coasts of Wales they are a common and delightful sight for summer hikers along the coastal paths. Their distinctive parrot-like beaks make them very easy to identify.
