This bird is non-migratory, makes a thundering noise when taking flight and its wings produce a whistling sound when flying. What is it? The Western Capercaillie (Tetrao urogallus).
Capercaillies are largest member of the grouse family with the male being twice the size of the female. Males average nine pounds and a wingspan of 35-49 inches and striking markings, while the female is only about four pounds and much plainer with brown feathers and silver barring. Interestingly, both sexes have feathered legs to help insulate from the cold. Capercaillies are found in shady forests with dense, damp undergrowth across Europe and Russia. They eat berries, shoots, stems and pine needles.
A breeding pair of capercaillies are on exhibit outdoors at the Toledo Zoo between the vultures and Great Apes.
