Bird utilization of wetland impoundments at cross creeks national wildlife refuge tennessee


, : Bird utilization of wetland impoundments at cross creeks national wildlife refuge tennessee. Journal of the Tennessee Academy of Science 66(4): 201-206

From 7 July 1989 to 15 June 1990, 1861 bird observations were recorded at seven wetland impoundments on Cross Creeks National Wildlife Refuge in Stewart County, Tennessee [USA]. For most observations made from early October through 15 June, each bird observation was assigned to one of 19 activity categories. A list of 159 different bird species was compiled. Ten species groups were identified, and 15 rare or vagrant species were listed. Feeding, resting, and flying were the three most common activities. Waterfowl were observed feeding and resting much more frequently than any of the other species groups. Feeding was also important to the shorebirds-gulls-terns group, especially the shorebirds. Raptors were observed flying more frequently than any of the other species groups. Overall, 300 times as many individuals were observed feeding as flying. Pools 2 and 4 were the most frequently utilized impoundments. Waders were most often found at sites having escape/temporary roost sites, and localized concentrations of fish caused by receding water levels. Pool 4 supported the highest number of waterfowl, raptor, and passerine species. Pools 2 and 4 were the two most important impoundments to the shorebirds-gulls-terns group.
