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.

With a total range in Europe and Asia of about 32 million square kilometres (12 million square miles) and a total population estimated to be between 250 thousand and 2.5 million, the IUCN lists the bird's conservation status as being of "least concern". The vast majority of eagle-owls live in mainland Europe, Russia and Central Asia, and an estimated number of between 12 and 40 pairs are thought to reside in the United Kingdom as of 2016, a number which may be on the rise. Tame eagle-owls have occasionally been used in pest control because of their size to deter large birds such as gulls from nesting.
