Understanding the foraging and nesting ecology of Wood Storks will play an important role in Everglades restoration because this species has specific resource requirements during the breeding season which ultimately affect nest success. I conducted a foraging habitat use and selection study, which indicated that Wood Storks from coastal colonies, Paurotis Pond and Rodgers River Bay, require a narrow range of water depths in the mangrove-saltwater marsh ecotone near their colonies as well in...

I conducted a foraging habitat use and selection study, which indicated that Wood Storks from coastal colonies, Paurotis Pond and Rodgers River Bay, require a narrow range of water depths in the mangrove-saltwater marsh ecotone near their colonies as well in the freshwater marsh habitats of the inland Everglades. Wood Storks nesting at the inland colony, Tamiarni West, relied heavily upon nearby freshwater marsh habitat and selected foraging sites associated with shrub swamp habitat as well as optimal water depths. The observational nesting ecology study of Wood Storks showed marked differences in parental nest attendance and food delivery rates between the two years of study, 2005 and 2006, which had different hydrological patterns.

The vulnerability of prey to capture plays a fundamental role in determining overall prey availability for wading birds. Structural complexity can act to decrease prey vulnerability and influence foraging habitat selection. To determine how structural complexity can affect habitat selection I conducted a use vs. availability study throughout the Florida Everglades in 2005 and 2006.

Show moreThe vulnerability of prey to capture plays a fundamental role in determining overall prey availability for wading birds. Structural complexity can act to decrease prey vulnerability and influence foraging habitat selection. To determine how structural complexity can affect habitat selection I conducted a use vs. availability study throughout the Florida Everglades in 2005 and 2006. Results indicated that wading birds chose foraging sites that had less emergent vegetation and a thicker flocculent layer relative to random sites. Submerged vegetation, and the height of emergent vegetation did not affect wading bird site selection. A difference in habitat selection between years was evident due to hydrological conditions. Ideal hydrological conditions are probably the most important parameter to wading bird success. Other factors affecting prey vulnerability became increasingly important in years of poor hydrology, probably because the penalty for choosing low quality foraging habitat would be greater than in years of more optimal conditions.
