. The Canadian field-naturalist. *-'â¢Â«**«â '144 .<#* 1^. Figure 1. Observers searched the islands and recorded information on birds and nests. Note the rugged terrain and abrupt shoreHnes which provided a diversity of rock, pool, tundra, wood, and lake habitats. CANADA GOOSE. Branta canadensis. McDonald once ob- served a pair with three goslings here but noted this species was a rare breeding bird among the islands of Great Slave Lake. Canada Geese regularly nest west of the lake and north of the MacKenzie River. A pair with young was observed on Kam Lake, 1.5 mi (2.4 km) southwest of Yellowknife, by local residents in 1972. MAI I ARD Anas platyrhynchos. Lone females have been sighted during several visits in late June and early July. A pair was observed on 5 July 1973. McDonald considered this species to be an occasional nesting bird. Weller et al. (1969) found one nest. PINTAIL Anas acuta. One to three pairs regularly nested on the islands and transients, mostly females, were frequently observed. In 1968, Weller et al. (1969) found two nests with five and six eggs. A nest with seven eggs was found on 23 June 1971, and a female with five la ducklings was observed on 18 July 1970. A total of 4 pairs, 2 males, and 16 females (6dd:2099) were counted on the islands during various visits (1969 1973). This species was observed most often on the smaller, outer islands which were more barren. GREEN-wiNGED TEAL. Anas crecca carolinensis. A breeding population of three to five pairs regularly occurred on the larger, more wooded interior islands of the complex. Adults were recorded on every visit; nine males and five females were counted in 1973. Weller et al. (1969) found one nest and sighted six adults in 1968. A female with five Ila ducklings was observed on 17 July 1970, and another female with seven 111 ducklings was sighted on 22 July 1972. Both broods were found on small interior pools of the larger islands. On 4 July 1973, a female was flushed from a nest
