The effect of weather conditions on the fall migration of seven duck species was studied in the Illinois and Mississippi River Valleys of Illinois, October 1-December 5, 1948-1968, and on observed flock arrival and departure dates. Arrivals were treated as if the ducks departed Fargo, ND, the evening before they arrived, and departures were related to weather conditions at Peoria, IL. A stepwise multiple regression equation was used to evaluate the effect of weather elements on duck departures. Correlations were highest for mallards (Anas platyrhynchos) and canvasbacks (Aythya valisineria). Since correlation of weather conditions with duck departures generally was low, endogenous (physiological) factors apparently affected departure time more than exogenous (environmental) ones. Temperature and pressure were the weather elements most frequently associated with duck departures. (Modified author abstract).
