Seed preferences by birds: Effects of the design of feeding-preference experiments
We analysed the effects of the design of feeding-preference experiments in a study of seed selection by Rufous-collared Sparrows Zonotrichia capensis. We presented eight seed options in multiple- and simple-offer experiments. Statistical results indicated that in multiple-offer tests there were thre...
