Perching Birds: Passeriformes

Passerines are found in grasslands, woodlands, scrublands, forests, deserts, mountains, and urban environments. They are widely scattered throughout arid (dry) to wet, and temperate (mild) to tropical climates, especially liking areas filled with trees because most of the birds are arboreal; that is, they live primarily in trees. Although passerines are found in most areas of the world, they avoid areas with permanently frozen land, or permafrost, that are always covered with snow and ice.
