The curious up-turned red bill and the white under parts were easily recognized even in the dark recesses of its nesting caverns. There was only a single egg in each case, which was lying cm the bare rock or soil or on a bed of loose pebbles; no nesting material had been brought in. The paroquet auklet breeds abundantly on the high rocky islands of northern Bering Sea and into Bering Strait. On the precipitous cliffs of St. Matthew Island, 200 feet or more above the sea, we saw a few pairs apparently breeding among the fulmars and puffin;, but their eggs were beyond our reach in the inaccessible crevices in the rocks. They were so tame and unsuspicious that I took a snapshot at one as it sat on a lofty pinnacle of rock within a few feet of me, watching the cloud of fulmars sailing below. Eggs.--The single egg is practically "ovate" in shape, with a slight tendency toward " elliptical ovate " in some specimens. The shell is finely granulated, almost rough and without any luster. The color is usually dull white or bluish white, but some eggs are decidedly bluish, about the color of heron's eggs, but darker than the palest of these. The measurements of 33 eggs, in various collections average 54.3 by 37.3 millimeters: the eggs showing the four extremes measure 58 by 33.5, 57.5 by 40, 51.5 by 37, and 52.5 by 33 millimeters. Plumages.--The downy young, when first hatched, is " fuscous black" on the crown, "fuscous," "Benzo brown," or "hair brown" on the back, sides, throat, and breast, and " pale drab gray " on the belly....
