Egyptian Goose
The Egyptian goose - also known as the Nil goose - is named for its place of origin (being the Nile Valley in Africa) and is a large, very distinctive waterbird with conspicuous eye patches of dark chocolate-brown. The female resembles the male, though is smaller, often with darker markings on her beak. The genders can also be told apart by their calls, as the male makes a strong, hoarse hissing noise, while the female produces a harsh, trumpeting quack. Young Egyptian geese have a duller color and have a gray tinge on their forewings, and their crown and neck are darker, with yellowish legs and beak.
