Time-activity Budgets of Yellowlegs in Managed Tidal Impoundments and Adjacent Tidal Marshes

SEAFWA Journal Volume 3, March 2016

Managed tidal impoundments are man-made wetlands constructed from natural tidal marshes and swamps with embankments and water control structures that manage water levels using tidal cycles. In South Carolina, 28,000 ha of managed tidal impoundments potentially provide important habitat for migrating and resident wildlife. The importance of traditionally-managed tidal impoundments relative to natural tidal marsh to migratory birds is poorly understood. Examining how birds allocate their time on managed tidal impoundments and natural tidal marshes can provide insight into whether birds are...

Annual Habitat Selection by Mottled Ducks in Coastal South Carolina

SEAFWA Journal Volume 2, March 2015

Mottled ducks (Anas fulvigula) are endemic to Gulf Coastal United States, Florida, and Mexico. Birds from Florida, Louisiana, and Texas were released in coastal South Carolina from 1975 - 1983, and subsequent banding data suggest a dispersing and increasing population in the state. Because autecology of mottled ducks is little known in South Carolina, we radio-marked 116 females in August 2010 - 2011 in the Ashepoo, Combahee, and Edisto Rivers Basin to assess habitat use throughout the annual cycle. We monitored habitat use by aircraft during fall-winter and via ground reconnaissance...
