An illustration of a Phoebe's nest in a box. The genus Sayornis is a small group of medium-sized insect-eating birds in the Tyrant flycatcher family Tyrranidae native to North and South America. They prefer semi-open or open areas. These birds wait on a perch and then catch insects in flight, also sometimes picking them up from the ground. Their nest is an open cup sometimes placed on man-made structures. They often slowly lower and raise their tails while perched.

Common European Nuthatch

A small, omnivorous bird, which gets its name from the hatches or hammerings it leaves on nuts.

The nuthatches are a genus, Sitta, of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upperparts and a black eye stripe. Most nuthatches breed in the temperate or montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American Red-breasted Nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation.

"The Ostrich is the largest of all living birds, standing from six to eight feet in height, and has been known from remote antiquity; Xenophon mentions it in the "Anabasis" as found in the plains of Artemisia, and there are frequent references to it in later Roman literature. Hunters report that the flesh is palatable. The ostrich is hunted and bred for the sake of the quill feathers of the wings and tail.The Ostrich is a vegetable feeder, but swallows stones, bits of iron, and other hard substances to aid the gizzard in its functions. On ostrich farms newly hatched birds have been observed to pick up little stones before taking any food. The wings are useless for flight, but of so much assistance in running that the bird can outstrip the fleetest horse."&mdash;(Charles Leonard-Stuart, 1911)

"The owl is a popular name for any nocturnal, raptorial bird, of which about 200 species are known. Their classification is in a very unsettled state. Willoughby's division into two sections&ndash; one having 'ears' or 'horns,' as the tufts of feathers on their heads were called, the other destitute of such appendages&ndash; was shown to be unnatural by Geoffroy St. Hilaire. The prevailing color of the plumage is brown, with a tinge of rusty-red, and it is exceedingly loose and soft, so that their flight (even in the larger species) is almost noiseless, enabling them to swoop upon their prey, which they hunt in the twilight. All owls cast up in the form of pellets the indigestible parts of the food swallowed. These castings may be seen under any owl-roost, and show plainly the great service these birds render to man in destroying rats and mice. They range over the whole globe."&mdash;(Charles Leonard-Stuart, 1911)
