We investigated habitat heterogeneity and patterns of avian taxonomic and functional diversity change across a decreasing patch‐size gradient in a critically endangered, fragmented forest‐system to elucidate: (1) habitat patch‐size and structural drivers of avian diversity change, (2) potential patch‐size thresholds at which avian diversity and habitat heterogeneity changes occurred and (3) avian...
Tannins are common secondary compounds in plant material and are known for their ability to bind to protein which reduces nitrogen availability in the diet. In fruits, these compounds are responsible for their astringency which is thought to result in reduced food intake. In this study, the repellent effects of tannins were examined in three species of frugivorous birds: red-winged starlings Onychognathus...
