Hawaiian Stilt Mob Display

Hawaiian stilts, or ae‘o, get combative as breeding season approaches at Hanalei National Wildlife Refuge in Hawai‘i.

These territorial mobbing displays can involve dramatic flapping, kicking and pecking, and often indicate that it is almost breeding season.
The wetland at Hanalei National Wildlife Refuge is one of the most important in Hawai‘i because it provides habitat for several endangered birds, including the ae‘o.
