June 27th. — To-day, for the first time, I saw a Phalarope 

 making that peculiar whirligig motion on the water which is said 

 to constitute its nuptial or courting display. The particular 

 bird thus acting when, at about seven in the morning, I looked 

 out of my tent, was by itself, or, at any rate, there was no other

 these occasions one of the revolving birds seemed to think the 

 proximity too close a one, for it flew at the other, who flew a
