The tundra areas were usually dry and covered with a heath/lichen community, moss, grass, and the occasional arctic willow (Fig. 143). One nest was in wet, graminoid tundra. Nests (Fig. 144B) were depressions in lichen, moss, and sedge hummocks, and 1 was near a clump of arctic willow. All nests were woven cups of dead grass lined with feathers of Willow Ptarmigan and other species, and grasses. The outside diameter of 1 nest was 9 cm ( inches); inside diameters of 2 nests were 7 and 9 cm ( and inches); inside depths of 2 nests were 5 and 5 cm (2 inches). EGGS 9 nests with 3 to 6 eggs; 3E (3N), 4E (2N), 5E (3N), 6E (IN). INCUBATION PERIOD 1 nest, 11 days. EGG DATES 8 nests, 17 June to 21 July (12 dates). Breeding Distribution Breeding by the Lapland Longspur in Ontario was first confirmed in 1947 at Cape Henrietta Maria (Manning, 1952). All additional records have also come from the Cape region where the species is relatively common in summer (Baillie, 1962). It probably breeds along the Hudson Bay coast at least as far west as the Sutton River (Manning, 1952), but it does not appear to occupy tundra areas along the entire 245.
