Prothonotary Warbler Research in the Cache Wetlands
Jeff Hoover, Ph.D. is an Avian Ecologist with the Illinois Natural History Survey. He plans, develops and conducts field-oriented research on the ecology/ conservation of birds, with applications to conservation and management issues in Illinois. One of Dr. Hoover’s research projects takes him to the Cache River Wetlands.
Here, he has been conducting a long-term (11-year) study of breeding populations of Prothonotary Warblers (a migratory species that is a forested wetland specialist) in southern Illinois. This research has yielded information from >3,000 individually marked adults, >6,000 nesting attempts, >5,500 offspring produced and represents one of the most detailed and extensive data sets ever recorded for a migratory passerine. Innovative field experiments with this species led to the discovery that the between-year breeding-site fidelity of adults is driven by experience-based decision rules (based on their own reproductive success). This study system is now supporting many new research directions and collaborations which include analyzing stable isotopes in feathers to link breeding and wintering grounds and determine natal dispersal distances, modeling the evolution of host defenses against brood parasitism, determining factors affecting extra-pair paternity (EPP), and linking EPP to the subsequent breeding decisions of individuals.
