Abstract
A knowledge of the relative masses of the primary feathers is necessary to compute the percentage of feather mass grown by a bird moulting its primaries, as a step towards estimating the parameters of moult using the Underhill‐Zucchini moult model. Also, wing shape characteristics can be described by fitting a polynomial regression model to the relative feather masses. This paper presents relative feather mass data for 38 species, primarily southern African. Further data are required to evaluate the concept of fitting mathematical models to describe wing shape.Keywords
