July 11, Glacier Bay, Two arctic terns shot today appear not to have bred, One contained ova about the size of 208 shot; the larger ones of the other were about like 2610, July 20, Glacier Bay, Littlejohn and I opened a number of nests of Somateria cirrhata (Tufted Puffin) - the 16th, Sneak appeared to be finished, having some straws in the bottom of the burrow; others were not finished; one had one egg in it, and another had a young bird about three days old in it. The same day we saw a loon, probably the red-throated, at the edge in a fresh water pond on the island opposite the one the puffins nests were on, From her actions we thought she had a nest in the grass bordering the pond, and looked for it; while doing so we flushed a scaup duck (ring-necked?) from her nest, and later I found the two loon eggs laying on the ground with scarcely any nest material about them. They were two feet or so from the water and a wide trail was beaten from the water to the nest and on back out of the grass, The incubation was so far advanced
