Abstract

Types of prey consumed by endangered Wood Stork (Myeteria americana) in coastal habitats have received little study. We documented prey items fed to stork nestlings in two coastal and two inland colonies in Georgia in 1995. Fish from brackish/saltwater habitats dominated the coastal the regurgitation samples, making up 65-93% of individual prey items and 49-74% of prey biomass collected, Mummichogs (Fundulus heteroclitus) were the most common single prey item found in the coastal samples. Inter-colony differences in the remaining coastal prey species were presumably due to differences in foraging habitat type (freshwater vs. saltwater) and their proximity to each colony. Prey from saltwater habitats were significantly shelter and weighed less than prey from freshwater habitats. Freshwater prey items fed to nestlings in all foul colonies were reasonably similar; containing varying percent ages (frequency and biomass) of redfin pickerel (Esox americanus), bullhead (Ameiurus spp.) and sunfish (Centrarchidae).
