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
The spot-bellied eagle-owl ("Bubo nipalensis"), also known as the forest eagle-owl is a large bird of prey with a formidable appearance. It is a forest-inhabiting species found in the Indian Subcontinent and Southeast Asia. This species is considered part of a superspecies with the barred eagle-owl ("Bubo sumatranus"), which looks quite similar but is allopatric in distribution, replacing the larger spot-bellied species in the southern end of the Malay Peninsula and the larger island in Southeast Asia extending down to Borneo.
