Abstract
The method recently advocated by Haney and Solow (1992: J. Field Ornit hol. 63:43-52) for the analysis of resource use and selection does not recognize the underlying structure of the data, so is inappropriate. In particular, it ignores the unit-sum constraint, requires independen ce between observations, and does not allow for extra-binomial variabi lity. Compositional analysis, which is tailored to the data structure, and provides power and flexibility in its application, is recommended instead.
