Various ecological and biological aspects of the wood duck (Aix sponsa)were investigated in the elm-ash-maple (Ulmus-Fraxinus- Acer) bottomland timber impoundments at Montezuma National Wildlife Refuge in central New York. Major areas of research included (a) a description of the forest stand with special reference to the ecological impact of seasonal impoundment, (b) the pattern of occurrence and use of natural nest cavities by wood ducks, (c) the nesting response of wood ducks to nest boxes, (d) an investigation of dump nesting, (e) mark-recapture estimates of annual duckling production, (f) a study of vernal pool invertebrates, and (g) a study of brood usage and survival. Spring flooded green timber was found to produce ideal breeding habitat for wood ducks in providing ample acceptable nest cavities (1.60 per acre)and an abundance of early spring (vernal pool) invertebrate food resources, including fairy shrimp (Chirocephalopsis bundyi), cladocerans (Daphnia pulex), mosquito lar.

Natural cavity nesting, brood movements, and survivorship of wood ducks (Aix sponsa) were studied for 2 years (1984-85) at Muscatatuck National Wildlife Refuge in south-central Indiana. Study objectives were to (1)determine the availability and use of natural tree cavities for wood duck nesting; (2) determine the availability and use of brood habitat;and (3) calculate a fledging rate for wood duck broods on Muscatatuck,NWR. Suitable tree cavities for wood duck nesting were sampled via 381 0.5-ha plots poststratified into bottomland and upland categories.Examination of potential cavities showed that 15% (122) of apparent entrances (789) were suitable cavities, and the 3,127-ha refuge had 2,195 +- 537 (95%) CI) cavities suitable for wood duck nesting. Areas with mature or sawlog trees had 1.69 +- 0.22 (x +- SE) cavities per ha and all the forested area on the refuge contained 1.23 +- 0.16 (x +- SE)cavities per ha. American beech (Fagus grandifolia), red maple (Acer rubrum), and Ame.
