NAME: The English name ‘Stilt’ refers to the very long legs of this bird species relative to the body size.  The Latin name ‘Himantopus’ is from Greek and refers to the long thin legs of the species. The word ‘mexicanus’ in the Latin name is due to this bird being a sub-species of the Black-necked Stilt, which is widespread in Mexico and South America. However, the latter is itself sometimes treated as a subspecies of the Black-winged Stilt. And the name ‘knudseni’ was given to this bird in memory of Valdemar Knudsen, a Norwegian sugarcane plantation pioneer in Kauai.
HABITAT: Shallow wetlands.
DIET: Small fish and invertebrates.
NESTING: The Hawaiian stilt nests on mudflats in a shallow depression. This is a species that will fake an injury to try and lure a predator away from its nest.
DISTRIBUTION: Endemic to the main Hawaiian Islands in loose colonies. Bird numbers are under 2,000.
CONSERVATION: The Hawaiian stilt is endangered, for the same reasons as the Hawaiian Coot and the Hawaiian Gallinule. This means from loss of habitat and predation by introduced animals such as the mongoose. In addition, because of its smaller size, it is also hunted by the endemic Black-crowned Night Heron.
SIMILAR SPECIES: See above under ‘Name’.
