_Spring._--The spring migration is almost directly north from the Gulf of Mexico to Great Slave Lake and then down the Mackenzie Valley and other valleys to the Arctic coast. It is rare in spring on the Atlantic coast. R. J. Longstreet writes to me that he saw three on May 4 and 5, and four on May 8, 1925, in Volusia County, Florida. C. G. Harrold tells me that it is a common spring migrant in Manitoba, "even abundant at times, a flock of nearly 300 being seen in May, 1924, at Whitewater Lake." A. G. Lawrence records it, at the same lake, as early as May 5 and as late as June 2; he calls it "uncommon to fairly common." At Beaver Lake, in northern Alberta, William Rowan saw flocks of from 20 to 25 birds every day from May 20 to 28, 1924. P. L. Hatch (1892) says that, in Minnesota, "they come in small flocks, and keep mostly about shallow ponds, and along the smaller streams flowing through the marshes," but he has "found them on the sandy beaches of some of the larger lakes on several occasions." He says "they are shy and exceedingly vigilant, making it no easy matter to get them." _Nesting._--Comparatively little is known about the nesting habits of the stilt sandpiper. Roderick MacFarlane (1891) found it "fairly abundant on the shores of Franklin Bay, where a number of nests with eggs and young were discovered. It is, however, very rare in the interior, only one nest having been taken at Rendezvous Lake on the borders of the wooded country east of Fort Anderson." A nest with three eggs, found on June 22, 1863, is described in his notes as "near a small lake and composed of a few decayed leaves placed in a depression in the ground, partly concealed by a tuft of grass;" the female was flushed off the nest and shot. The nest found at Rendezvous Lake is not described, but one found at Franklin Bay, on July 6 or 8, 1865, containing four fresh eggs, was "a mere depression in the ground, lined with a few withered leaves and grasses."
