Small land birds were plentiful. Nighthawks and black swifts flew overhead, Brewer blackbirds hunted food on the shore, and red- winged blackbirds were accompanied by full grown young. At one place when the whistle of a pygmy owl was imitated numerous small birds came into an alder directly overhead. Amongst them were a pair of Bohemian waxwing, a pair of redstarts, a water thrush, a western tanager and a warbling vireo.

Covert Lake: About 1/4 mile long, 250 yards wide, in Lot 754 (Pre- emptor series, Map 3D, British Columbia Department of Lands), one- half mile south or Lacroix Lake. It is completely surrounded by black spruce forest and along the shores by floating bog covered with sedges, red osier dogwood and dwarf birch. The lake has a maximum depth of approximately 15 feet. The waters contain an enormous amount of the ivy-leafed duckweed that covers most of the bottom and reaches the surface in the shallower places where it is mixed with, or replaced by, lesser duckweed. Over about half the lake's area is a surface layer of the latter and a bottom layer of ivy-leafed duckweed. The only other food plant visible in this dense accumulation was a small amount of Potamogeton robbinsii. Adult damselflies were noted as relatively common, and dredging brought up leeches, amphipods Gammarus limnaeus and Hyalella azteca, the snails Helisoma subcrenatum (Carpenter) and Physella ampullacea (Gould), waterbugs Notonecta kirbyi Hung. and mayfly

nymphs.

Waterfowl observed were: mallard, female with brood and 1 eclipse male; baldpate, 2 females with broods; bufflehead, 3 year- lings

Like many lakes in the district, this is a feeding ground for transient waterfowl and is described as one of the best local duck- shooting places Lakes where lesser or greater duckweed is abundant usually are frequented by pond ducks in the early autumn and no doubt this food is the attraction here.

Maclure Lake: 2 1/2 miles long, 1/2 to 3/4 mile wide, three-quarters of a mile east of the confluence of the Bulkley and Telkwa Rivers. The coniferous forest surrounding the lake is partly cleared, the logged-off portions grown up with deciduous trees, chiefly aspen; tall willows are prominent in depressions. On the east Side the land rises to a low mountain of which part is forest of the pre- vailing type, part hayland and tillage. Except for half a mile or less on the west shore of open, hard beach fringed by alder and willow, the entire lake margin carries marsh growth varying in width from 50 feet to 100 yards. This is composed chiefly of round-stem bulrush and cattail, for the most part in separate beds but in several places these two plants occur in about equal pro- portion. A marsh of several acres at the north end has a navigable
