TextPublication details: Ithaca, NY : Cornell University, 1992.Description: xii, 121 leaves : ill. ; 29 cmOnline resources: Abstract: The use of bottomland hardwoods by nesting mallards (Anas platyrhynchos)was studied in western New York on the Iroquois National Wildlife Refuge and the state-owned Tonawanda and Oak Orchard Wildlife Management Areas.Nest searches were conducted in 550.0 and 712.6 ha of approximately 832.6 ha of available bottomland hardwoods in 1989 and 1990,respectively. Mallards began nesting as early as the third week in March and ended the first week in June, with nesting peaks occurring in mid-April and mid-May. A total of 239 nests were located on tree crotches, hummocks, tree stumps, tree cavities, and 'other' sites. Nest site use compared to availability indicated a significant preference for three crotches and stumps in 1989 (P < 0.05) and for tree crotches in 1990 (P < 0.05).
