108 THE CONDOR Vol. XVI days. The second trip, December 27, 1912, to January 13, 1913, I was accom- panied by Mr. O. J. Murie of the Fish and Game Commission during the entire period, and by Mr. Peck from December 27 to January 13. During this trip, we experienced some severe storms, especially that of December 28 and 29, when the rain and sleet fell in torrents accompanied by a strong wind. The third and fourth visits, from March 9 to March 21, and May 14 to May 20, 1913, I was accompanied by 'Mr. Murie for the entire period. During these two trips a part of the time was devoted to collecting small mammals. The list contains the water and shore birds only.

Specimens of all the species listed were secured with the exception of Great Blue Heron (Ardea 1;erodias), Killdeer (Oxyech?s vociferous) and Amer- Fig. 34.

Most of the shore line rises abruptly from the water, leaving no beach at high tide, although during the seasons of low tide a large part of the water recedes from the bay leaving extensive mud flats. On the west the bay is cut off from the ocean by a narrow sandspit, which averages not over half a mile in width. On the bay side of this spit a narrow "salt grass" tide flat extends north about four miles from the southern end of the bay. Most of the sandspit is barren of vegetation except a narrow belt of stunted pine (Pin, us covtorta), huckleberry, and a few scattered willows on the higher parts. Dense forests of spruce, hemlock and fir, with an undergrowth of salmonberry, cover the hills on the
