Eurasian eagle-owl
The Eurasian eagle-owl ("Bubo bubo") is a species of eagle-owl that resides in much of Eurasia. It is also called the European eagle-owl and in Europe, it is occasionally abbreviated to just eagle-owl. It is one of the largest species of owl, and females can grow to a total length of 75 cm (30 in), with a wingspan of 188 cm (6 ft 2 in), males being slightly smaller. This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish colouring and tawny. The wings and tail are barred. The underparts are a variably hued buff, streaked with darker colour. The facial disc is poorly developed and the orange eyes are distinctive.
Spot-bellied eagle-owl
This species is distributed the Lower Himalayas from Kumaon east to Burma, thence to central Laos and central Vietnam. They are found throughout the Indian subcontinent and peninsular Southeast Asia down into the southernmost limits of the range in Sri Lanka and to 12 degrees north in southern Thailand. The spot-bellied eagle-owl dwells mainly in primary or older second growth forests. Potentially, they can come to inhabit nearly all varieties of land-based habitats but prefer those such as dense, evergreen forests or moist deciduous forests within its range, though can range secondarily into tropical valleys, "terrai" and "shola" in the lower hills of India. Although often considered uncommon to somewhat rare, recent photographic evidence indicates that they are particularly widely found in different parts of India and may simply avoid detection, so long as appropriate wooded habitat remains. They are found in a range of climates from the temperate woodlands of Nepal to the humid, tropical rainforest of Southeast Asia. However. the spot-bellied eagle-owl is mainly a species of tropical and subtropical foothills, mainly being distributed at elevations of , though have been found at anywhere from sea-level to , the latter in the Transhimalayas.
