Observations of migrating Lesser Snow and Blue Geese (details of sightings and locations are given in Table 1.) Evidence for the two other direct flights was obtained in 1974. A major departure from the Hartney-Souris staging area began on the afternoon of 12 May, continued through the evening (and probably the night), peaked in the early morning of 13 May, and subsided by late morning of that day. Several sightings of migrating geese were made further to the north and east. On 13 and 14 May several flocks were seen flying over Winisk. The next major departure occurred from the Pilot Mound staging grounds beginning on the evening of 14 May and continuing through the late evening of 15 May. The departure and flight across southern Manitoba was observed both on the Winnipeg radar and by many volunteers. Sightings were again reported further en route and on the coast of Hudson Bay. On 16 May some 300 flocks, flying mostly from west to east, were observed at Winisk. Although the three cases just presented were by far the most obvious, the data also suggested other possible incidences of through-flights. On the other hand, scattered sightings of migrating Snow Geese were reported that did not appear to constitute major direct flights. Discussion The observations in Table 1 are evidence of through-flights from southern Manitoba to the coasts of James and Hudson Bays. Although they do not prove direct non-stop flights, they indicate that the geese did not spend several days in the interior, making the presence of major staging areas unlikely. Suitable staging habitat providing food, water, and safe roosting places probably does not occur in the boreal forest of northern Manitoba and northwestern Ontario in early spring.
