The second chapter focuses on foraging behavior of kingfishers and great blue herons, and shows that netting and perches can be used to successfully manipulate avian predation pressure. The third chapter uses this technique to examine what effects kingfishers and wading birds are having on stream fish assemblages, and shows that there are effects are on two of the most abundant minnow species, striped shiners and central stonerollers. The fourth chapter documents how facilitation occurs between avian and aquatic predators, resulting in more prey being consumed when both predators are together than expected based upon the number of prey each prey consumes in isolation. The last chapter shows that both birds and bass produce non-lethal effects on prey habitat use, movement rates, and foraging activity. Taken together, this work shows that avian predators play an important role in affecting fish populations in aquatic systems. Made available in DSpace on 2015-09-25T22:42:27Z (GMT).
