The Eagle Owl is a large and powerful bird, smaller than the Golden Eagle but larger than the Snowy Owl. It is sometimes referred to as the world’s largest owl, but this is actually the Blakiston’s Fish Owl, which is slightly bigger on average.[2][3] The Eagle Owl has a wingspan of 138–200 cm (55–79 in) and measures 58–75 cm (23–30 in) long. Females weigh 1.75-4.5 kg (3.9-10 lbs) and males weigh 1.5-3.2 kg (3.3-7 lbs).[4][5][6] In comparison, the Barn Owl weighs about 500 grams (1.1 lbs).
