Cogswell 1949 Mergus merganser Trinity River, Aug. 28 7/3 mi. N Yellow Creek, 400 ft., Humboldt Co. Calif. a flock of 14 G-plumaged individuals was resting on rocks at the upper end of an area of rapids in the river here as I approached about 1:45 p.m. They pushed off into the calmer water just upstream from their perches; and toward me, as I came up along the bank near them. Then, they swam out toward mid stream, turned & took flight headed downstream & around 2 bends of the river & out of sight. All of these appeared to be in typical full breeding plumage of the G; no call notes were heard. [These birds not at this place in a.m. of 29th.] Aug. 30 at least 18 G-plumaged birds seen in this vicinity this a.m. at 8:45 there were G swim- mng & diving in the shallow, relatively turbulent water over rocky bed just N. of the suspension bridge. They flew & joined 3 or 4 others along the W side of the stream just to the N. I shot at 1 of these which was up on a rock at the water's edge; wounded it, but it swam rapidly out into the stream & dived before I could get to it. I searched stream & banks for 1/2 hr. without finding it. The others flew downstream (N), and a few minutes later I counted 17 flying from that portion of the river.
