They are the only commonly found accentor in lowland areas, all the others inhabit upland areas Dunnocks were successfully introduced into New Zealand during the 19th century, and are now widely distributed around the country and some offshore islands. Favourite habitats include woodlands, shrubs, gardens, and hedgerows where they typically feed on the ground often seeking out detritivores as food. The main call of the dunnock is a shrill, persistent "tseep" along with a high trilling note, which betrays the bird's otherwise inconspicuous presence. The
Common ostrich is scarce in dry and hot environment, and this poses a challenge to the ostrich's water consumption. Also the ostrich is a ground bird and cannot fly to find water sources, which poses a further challenge. Because of their size, common ostriches cannot easily escape the heat of their environment; however, they dehydrate less than their small bird counterparts because of their small surface area to volume ratio. Hot, arid habitats pose osmotic stress, such as dehydration, which triggers the common ostrich’s homeostatic response to osmoregulate. The common ostrich is well adapted to hot, arid environments through specialization of excretory
