. Breeding birds of Ontario : nidiology and distribution. Birds; Birds; Birds. Smith's Longspur, Calcarius pictus (Swainson) Nidiology RECORDS 14 nests representing 1 provincial region. Breeds on open, treeless tundra. The few recorded nests suggested that this species preferred a grassy, somewhat wetter tussock tundra (Fig. 145) for its breeding habitat, in contrast to the dry heath-lichen areas selected by the Lapland Longspur. However, 3 nests were reported on raised, dry tundra areas and beach ridges. Nests were positioned on the ground in sedges and grasses, both long and short, and sometimes with mosses and lichens near the nest. One nest was in a clump of rhododendron, another under a small dwarf birch, a third was well hidden in long, dead grass clumps, and a fourth was on a hummock. Nests (Fig. 146B) were woven, sunken cups with coarse, dead grasses on their exterior, and were lined with fine grasses, feathers, and a few fine rootlets. One nest had a small grass ramp leading to it. Outside diameters of 5 nests ranged from 7 to cm ( to inches); inside diameters of 7 nests ranged from 6 to 7 cm ( to inches); inside depths of 7 nests ranged from to cm ( to inches). EGGS 8 nests with 3 to 5 eggs; 3E (IN), 4E (3N), 5E (4N). Average clutch range 4 to 5 eggs (7 nests). Three other nests each had 4 young, 2 others each contained 2 young, and a sixth contained 5 young. INCUBATION PERIOD No information. EGG DATES 8 nests, 22 June to 14 July (11 dates); 4 nests, 30 June to 2 July. Breeding Distribution The first breeding record for Smith's Longspur (Fig. 146A) in Ontario was secured at Fort Severn in June 1940 (Baillie, 1961). Most subsequent records were from the Cape Henrietta Maria region far to the east, but 2 additional breeding records (Shagamu River, Little Cape) suggest that this species may breed all along the Hudson Bay coast where tundra conditions 247.
