Kantak (1979) and Baird (1980) both postulate that conspicuous color may play a more important role in food selection by frugivores than the size or nutritional quality of the fruit. Knowledge of fruit preferences may increase the effectiveness of habitat improvement programs designed to benefit frugivorous birds. We conducted a study using two frugivorous birds, American robins (Turdus migratorius) and gray catbirds (Dumetella carolinensis), to provide data on food selection by frugivores in Kansas</p>10abird10adiet10afoot1 aHazelton, P.K.1 aRobel, R.J.  uhttp://lter.konza.ksu.edu/content/preferences-and-influence-paired-food-items-energy-intake-american-robins-and-gray-catbirds
