King, Warren B. 1964 BCF Cruises 26 a heavy bird, flying with continuous wingbeats. It was undoubtedly in the Stercorarious family, possibly a Skua. My description compares exactly with Sundell's Jaeger-like bird of yesterday. The "Wedgetail" at 1500 didn't look quite right. It was very grey, had very white ventral surfaces. Ventral wing surface showed too much white in the middle, and black edges were too thin. Flew rather more typically shearwater than most Wedge-tails, although difference here may be hair-splitting. Suspect larger numbers of Sooty Shearwaters tomorrow, although we turn North from today's east course. March 20--Starting 19 March 1964 a record is being kept of the two types of "Harcourt's" Storm Petrels we have been seeing. The first, hereafter called Type A, is slightly smaller, very bat-like in flight, using floppy wing beats, almost like a butterfly; while the second, called type B, is more petrel-like, slightly larger, flies very controlledly on stiff wings, arcing and scaling in a diminutive copy of Bulwer's Petrel. We suspect type A to be the true, O. castro and tyep B to be O. leucorrhoea Leach's Petrel, but nothing will be conclusively proved until both are collected. The light dorsal wing bars are more noticeable on B and it seems to be generally a lighter colored bird. Sooty Shearwaters were the big news today. Several certains and several possibles seen. Birds flying in typical Sooty Shearwater fashion but not revealing silver linings will be called either "Sooty Shear (?)" or Shear sp. with a note saying possible sooty shear, depending on degree of certainty. At 1426 two Sooty Shearwaters and a type B Harcourt's were flushed from the water by the ship. Four of today's Wedge-tails were dark phase and very dark indeed. Ventral surfaces
