Guard nests to increase nest success Bird Conservation

A study on Codfish Island (1,500 ha), South Island, New Zealand, in 2002 (Jansen 2005) found that 24 kakapo Strigopus habroptilus nests that were monitored by volunteers produced 26 chicks, of which 24 fledged. Volunteers followed a strict set of protocols and reported to ‘controllers’ frequently to ensure eggs survived. The authors argue that reproduction would have been lower without the intensive monitoring that volunteers provided (and which would not have been possible financially with paid staff).
