This study of a Type 5 Federal Wetland Management Area showed that: (1) production (young remaining on the area to flight stage) in birds per acre was 0.74 in 1967 and 0.57 in 1968; (2) the greatest temporary use of the area was mode by blue-winged teal, 64 being sighted at one time; and (3) artificial loafing structures may increase use of a wetland by breeding ducks
