[[underline]] inca [[/underline]], Nov 14, 1955, VI.  [[image- number 81 in circle in upper right corner]]

Two birds circling near me. Probably reacting to me. Flying in "buoyant" flight part of the time. Several LCN's. Also much flying with G  In "hanging" head & neck posture drawn on preceding pages [[image - bird in flight with head pointed downward and bill open]]  Some G's with extremely wide open bills  Once, one of the birds, in wide open G, suddenly flies several yards [[underline]]with suddenly slower wing-beats [[/underline]],[[underline]]of wide amplitude.[[/underline]] Must have been at least 6 or 7 strokes of this (which might be called the "real" Butterfly Flight). Then resume ordinary flight, circle once more, birds separate, land in different places

  There is no doubt but that the aerial LCN appears in the same circumstances as the aerial LCN of gulls. Given by stray birds, for instance, once or twice when flying over me. Certainly not common however, relatively less common, in all probability, than the LCN's of most of the species I have studied. 

  Forgot to add that the other day, when I was in blind near a potential colony area when it was visited briefly by a small flock, noted that several birds entered holes very briefly.

  The Erratic Flights of this species, the ones I have seen at least, contain much less twisting & turning than those of Bonaparte's Gull

  Well, [[underline]]to sum up about fish flight [[/underline]], [[underline]] there doesn't seem to be any. [[/underline]] I haven't seen a flying bird carrying a fish all morning. [[underline]] I haven't seen any [[female symbol]] fed on the communal rocks.  I haven't any trace of High Flight or Gliding Descents either. [[/underline]] This apparent absence is quite remarkable, and undoubtedly of considerable comparative significance.

  Bird flying in group near me  Gives 2 LCN's, in "hanging" posture, with slow wing-beats of great amplitude (possibly a little less exaggerated than the "Butterfly Flight" described above)

  The whole status of "buoyant" flight is rather a prob
