The secretarybird is instantly recognisable as a very large terrestrial bird with an eagle-like head and body on crane-like legs. It stands about 1.3 meter tall. The secretarybird is endemic to sub-Saharan Africa and is generally non-migratory, though it may be locally nomadic as it follows rainfall and the resulting abundance of prey. The species is also found at a variety of elevations, from the coastal plains to the highlands. The secretarybird prefers open grasslands, savannas and shrubland rather than forests and dense shrubbery which may impede its cursorial existence. The large frogmouth is found in Brunei, Indonesia, Malaysia, and Thailand, in subtropical or tropical moist lowland forest. Logging of its habitat poses a risk to its survival, and the International Union for Conservation of Nature has listed it as being "near-threatened". The large frogmouth is considerably larger than other members of its genus and grows to a length of about 42 cm. The behaviour of this bird is not well known. It hunts by night, on the ground and in the canopy, feeding on insects such as grasshoppers and cicadas. It roosts by day, perching on a branch or hidden in a hole, singly or possibly in pairs. The long-tailed tit or long-tailed bushtit occasionally referred to as the silver-throated tit or silver-throated dasher, is a common bird found throughout Europe and the Palearctic. This species has been described as a tiny, round-bodied tit with a short, stubby bill and a very long, narrow tail. Vocalisations are a valuable aid to locating and identifying these birds. The long-tailed tit is insectivorous throughout the year. It eats predominantly arthropods, preferring the eggs and larvae of moths and butterflies. Occasional vegetable matter is taken in the autumn. The blue crowned pigeon,also known as the common crowned pigeon or western crowned pigeon, is a large, blue-grey pigeon with blue lacy crests over the head and dark blue mask feathers around its eyes. Hunted for food and its plumes, it remains common only in remote areas. Due to ongoing habitat loss, limited range and overhunting in some areas, the western crowned pigeon is evaluated as Vulnerable on the IUCN Red List of Threatened Species. The grandala ranges across the northeastern Indian Subcontinent and some adjoining regions, existing primarily in the low-to-mid altitudes of the Himalayas. It is found in Bhutan, India, Myanmar, and Nepal, as well as Tibet and other areas of China. Often seen swirling in flocks above mountain passes, scrubby alpine forests, and highland meadows, this large thrush is unlike any other.
