An effective technique for capturing Hawaiian common gallinule

The Hawaiian common gallinule ( Gallinula galeata sandvicensis ) is endemic to Hawai‘i and is state and federally listed as endangered. Capture provides an opportunity to measure individual morphometrics and, through marking, monitor survival and movement. This paper describes a technique for capturing adult and juvenile Hawaiian common gallinules using a baited remote‐operated cage trap. The primary advantages of this technique are its ability to selectively capture birds, low injury rate, and minimal training requirements for the operator. The method can be adapted to related rallids with similar behavior and habitat use.
