In this study we investigate whether bite force is directly
related to husking time in two groups of finches, the estrildids
(Estrildidae) and fringillids (Fringillidae). From a previous
study with various seed species we know that differences in
husking performance between these two groups of finches do
occur (R.B., personal observation). In the study reported here
we offered a single seed species to a number of different
species of both families, and husking times are related to bite
force measurements of the same individuals.
