Kākāpōs see breeding surge as rimu mast may boost chick numbers

A mass fruiting of native rimu trees has prompted increased breeding among New Zealand's roughly 236 kākāpōs, and officials expect more than 50 chicks to hatch.

Conservationists in New Zealand report an unusually large rimu fruiting this year that has led to increased breeding activity among kākāpōs. The kākāpō population is about 236 birds and their breeding is normally linked to rare mass fruiting events of the native rimu tree. Past recovery efforts have involved physically protecting birds from introduced predators and have progressed slowly. Department of Conservation biologist Andrew Digby said the rimu feast is spurring mating and he anticipates more than 50 chicks may hatch this season. Key details: - The current kākāpō population is reported as about 236 birds. - Kākāpō breeding is tied to infrequent mass fruiting of the native rimu tree; the last such event was in 2022. - Rimu fruit provides important nutrients such as calcium and vitamin D that support breeding. - The Department of Conservation says this mast has prompted a strong breeding response and an expectation of over 50 chicks. Summary: Officials say the expected hatchings could produce the species' most prolific season on record. Undetermined at this time.
