"Brown Booby," Wikipedia, the free encyclopedia. The booby's head and upper body (back) is covered in dark brown or black, with the remainder (belly) being a contrasting white. The juvenile form is gray-brown with darkening on the head, wings and tail. While these birds are typically silent, bird watchers have reported occasional sounds similar to grunting or quacking. Their beaks are quite sharp and contain many jagged edges. They have short wings and long, tapered tails.
