Steps to reproduce
Two specimens of Little-spotted kiwi (A. owenii), one female (no. 55790) and one male (no. 55789), and one specimen of male brown kiwi (A. mantelli) (no. 56040) were scanned using the computed tomography facility (CT), at Massey University, New Zealand (power: 90 kV, 88 mA; resolution: 0.8 mm on each axis). We used AVIZO (version 6.3; FEI Visualization Sciences Group) to reconstruct bone models from the CT scans and imported the models in obj file format into AUTODESK MAYA (2018, Autodesk Inc., San Rafael, CA, USA). We observed mounted kiwi skeletons at Massey University at Palmerston North and at the Muséum National d’Histoire Naturelle (MNHN) osteological collection specimen MNHN 2012-194) to complement information on missing ribs. Radiographies of a gravid alive brown kiwi (Calder, 1979) and of a non-gravid alive Brown kiwi (Massey University), as well as our observations of a brooding kiwi bird were used to approximate the position of the brown kiwi bones in these three postures using AUTODESK MAYA software.
