| 520 | 3 |a"In 1985 and 1986, a repeat survey of migrant waterfowl use was undertaken along the Ontario St. Lawrence River and northeastern Lake Ontario in order to supplement and update the findings of the original 1976/7 survey. As in that work, the birds were counted from a small fixed-wing aircraft flying a standardized route on a similar schedule. The route was divided into 12 zones and the results summarized as waterfowl days for each species group (geese, large and small dabblers, bay ducks, goldeneye, sea ducks, mergansers); comments on individual species are made where possible"--Abstract. |
