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.
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN. Originally from South Asia, it has been introduced to tropical regions worldwide where it outcompetes native birds for nest cavities. Despite its invasive status, the myna is an intelligent and charismatic bird capable of mimicking human speech.
