Fairy Gerygone

Adult birds have olive upperparts and yellow underparts, brownish tails, short black bills and legs, and red eyes. The male has a black throat. The subspecies flavida can be distinguished from subspecies personata by the white tip of its tail.

It is found in Australia, Indonesia, and Papua New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. The fairy gerygone is listed by the IUCN as being of Least Concern. No particular threats have been identified and the bird has a wide range and stable population.

Male fairy gerygones hold themselves erect and sing a loud melodious song when they hear the calls of predators, particularly their main predator the black butcherbird. The purpose for this is unclear, though it is possibly a form of advertising to potential mates, promoting the male's prowess at singing in times of danger. The fairy gerygone nests near wasp nests, possibly to keep itself safe from predators.
