About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
Mute Swan
The mute swan is one of the heaviest flying birds, with males weighing up to 14 kg. Despite its name, it is not truly mute, producing hissing, grunting, and snorting sounds. Mute swans form lifelong pair bonds and their aggressive defense of nesting territory is well known.
