125 Journal R.E.Johnson 1968 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. Longspur Nest 3-6 Arrival at Nest Departure from Nest Time away from nest feeding Time at nest [min] My arrival 3:38 PM (8) 3:46 PM 3:46 ½ 2 ½ ½ 3:49 3:49 ½ 4 ½ ½ 3:54 3:54 ½ 6 ½ ½ 4:01 4:03 3 ½ 2 4:06 ½
