Kākāpō (Strigops habroptilus) egg fertility on Anchor and Whenua Hou islands, New Zealand, 2019 breeding season

Abstract

This dataset contains information on the fertility and physical characteristics of kākāpō (Strigops habroptilus) eggs laid on Anchor and Whenua Hou islands, New Zealand during the 2018/19 breeding season. Of the 252 total eggs laid, 129 failed to develop; undeveloped eggs were dissected, fixed in formalin, and then inspected using fluorescence microscopy at the University of Sheffield UK. For all eggs, data are provided on mother and clutch of origin, developmental stage reached, and maternal mating behaviour. For dissected undeveloped eggs, additional data include fertilisation status, numbers of sperm visible on the perivitelline layer, egg size and weight, dry eggshell weight, and yolk and albumen weights.

All data were collected by the authors or by other staff within the New Zealand Department of Conservation Kākāpō Recovery Team. All data collection was carried out by trained and experienced staff following established conservation management or laboratory protocols. All data were collected in field or lab notebooks in the first instance, then transcribed to digital spreadsheets. Measurements reported in data files were checked against original notebooks before data deposition. Original notebooks are held at the University of Sheffield, UK, and with the Kākāpō Recovery Team, NZ; the latter also maintains a comprehensive kākāpō database. See documentation file for further methodological details and data collection roles.
