Sampling comments: "Wild birds were collected every other week from March 1997 through July 1998 using mist nets positioned 275 m along a footpath that approximately followed the 610-m elevation contour. Ten black nylon mist nets (2.6 by 12 m, 38-mm mesh) were opened for 4 h from 0700-1100 hours" (this presumably means on 26 + 5/12 x 26 = approximately 37 days)
