Size and flight capability of Anas chathamica, an extinct duck from Chatham Island, New Zealand
@inproceedings{Williams2015SizeAF, title={Size and flight capability of Anas chathamica, an extinct duck from Chatham Island, New Zealand}, author={Murray Williams}, year={2015} }
Measurements of major bones from Chatham Island’s extinct duck Anas chathamica (formerly placed in Pachyanas) were used to estimate the duck’s likely mass and flight capability. Mass estimates derived from published regression equations relating least femur circumference to body mass for volant birds ranged between 1,500–2,300 g, and those based upon tibiotarsus least circumference ranged between 1,670–2,400 g, providing an overall average mass estimate of c. 1,900 g. The bimodal size-frequency… Expand
