June 26 Amchitka Island, Alaska (cont.)
Collected by Dr. J. from large flocks sitting on the water ½ mile or less off shore. Tufted Puffins outnumbered Horned Puffins by at least 5 to 1.
The 2 species mixed very little, flocks usually being pure species groups. One ♀ Tufted Puffin contained a collapsed follicle indicating she had laid already, but the other birds showed no indication of being reproductively active now or in the recent past.
In the afternoon I drove to the wet tundra plots & again watched the feeding female Lapland Longspur at nest 3-6 to determine feeding rate (trips of ♂ to nest to feed young). from the same direction but I watched from slightly further away than on the preceding day.
