Gilmore 1931 HARLEQUIN DUCK (4) Oct. 3 (cont.) Paul Ingramson, boat man on the "Kanaga Native" states that he has seen "Rock Ducks" up in the hills along streams and believes that they nest along the head waters of the creeks & streams. He seems to be quite reliable but I have my doubts about the rock duck story. Oct. 4 Agamugik Bay, W. Unalaska Bay Common here - there seem to be more adult T's than around Unalaska. I watched a wounded one swimming underwater in about a fathom of water. It swam smoothly & power- fully, using short choppy wing strokes. The first time it dove it stayed under about a minute & a half. The next time about a minute & the next time about 10 seconds. Soon it was so exhausted that we picked it up from the surface with ease. When we lost sight of it down in the water, we could follow its course by a path of bubbles.
