Effects of Human Disturbance on Foraging Behavior of Dunlins Calidris alpina
Studies on effects of human activity on the foraging behavior of dunlins Calidris alpina were conducted using methods of focal-animal sampling and human-disturbance experiment at the beaches of Yanpen and Yuecheng, Yueqing bay in Zhejiang Province from November 2003 to March 2004. Results of focal-a...
