On a semibarren island about 50 miles north of Fort Resolution, where we were detained by high winds July 11 to 14, five pairs were found breed-. Fig. 15.

Several shallow ponds, from 5 to 50 yards wide and connect- ing with the lake at times of high water, extend nearly across the central part of the island, and each was occupied by a pair of loons, together with their two young, a few days old (fig. 15). The age of the different broods varied but a day or two. The nests, rather well made of dry grass, were placed at the margins of the ponds, usually in a patch of grass, and in one or two cases still contained the abandoned egg shells. When the nesting pond was approached, the male usually flew away, but the female invariably refused to leave her offspring, and if absent soon appeared and alighted beside them, diving, swimming about, and encouraging them in their efforts to "Auk, XXV. p. 68, l' Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Preble, Edward Alexander, 1871-1957.
