They have short wings and thin down-turned bills. Several species often hold their tails upright. All are insectivorous. Order: PasseriformesFamily: Polioptilidae  These dainty birds resemble Old World warblers in their structure and habits, moving restlessly through the foliage seeking insects. The gnatcatchers are mainly soft bluish grey in colour and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (especially males) and long, regularly cocked, black-and-white tails. Order: PasseriformesFamily: Regulidae  The kinglets are a small family of birds which resemble the titmice. They are very small insectivorous birds in the genus "Regulus". The adults have coloured crowns, giving rise to their name. Order: PasseriformesFamily: Muscicapidae  The Old World flycatchers are a large family of small passerine birds. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. Order: PasseriformesFamily: Turdidae  The thrushes are a group of passerine birds that occur mainly but not exclusively in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs. Order: PasseriformesFamily: Mimidae  The mimids are a family of passerine birds which includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalization, especially their remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. The species tend towards dull greys and browns in their appearance. Order: PasseriformesFamily: Sturnidae  Starlings and mynas are small to medium-sized Old World passerine birds with strong feet. Their flight is strong and direct and most are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. The plumage of several species is dark with a metallic sheen. Order: PasseriformesFamily: Bombycillidae  The waxwings are a group of passerine birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name.
