The Eurasian Eagle-Owl is a species of eagle-owl that resides in much of Eurasia. It is one of the largest species of owl, and females can grow to a total body length of 30 in, with a wingspan of 4 ft 4 in to 6 ft 2 in. Males are slightly smaller. Females can weigh from 3.9 to 10.1 pounds and males can weigh from 2.7 to 7.1 pounds. This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish coloring and tawny. The wings and tail are barred. The under parts are a variably hued buff, streaked with darker color. The facial disc is poorly developed and the orange eyes are distinctive. Besides the female being slightly larger than the male there is little external differentiation between them. The great size, bulky, barrel-shaped build, erect ear tufts and orange eyes render this as a distinctive species.
