Aeʻo

Himantopus mexicanus knudseni

Also known as Hawaiian Stilt, Kukuluaeʻo, Hawaiian Black-Necked Stilt

Hawaiian stilts strut through shallow mudflats and taro patches on striking, needle-thin pink legs that account for more than half their total height. Their sharp, yapping alarm calls echo across coastal wetlands whenever intruders approach their ground nests, which adults aggressively defend using vocal distraction displays. Adapted to Hawaii's freshwater and brackish ecosystems, these shorebirds forage by snatching aquatic insects, worms, and small fish directly from shallow water.

What to notice
Recognizable by bright pink legs, black upperparts, and black coloration extending further down the face and neck than mainland stilts.
Support conservation
Maintain a respectful distance near wetland sanctuaries, never approach nests, and strictly follow posted refuge guidelines.
Responsible observation
  • Observe from a distance: Use binoculars or a spotting scope to avoid disturbing feeding or nesting birds.
  • Stay on trails: Keep out of protected mudflats and vegetated pond edges during the spring breeding season.
  • Control pets: Keep dogs on leashes near coastal wetlands to protect ground-nesting wildlife.
