over the ground, and it may be purely a matter of aerodynamics). All the aerial L C's so far seen have been accompanied by the same slight-moderate forward stretching of the head & neck, horizontal head.

Terrific Silent Panic 7:05 Don't know why. [[underlined]] Very few erratic flight patterns in this panic [[/underlined]]. Panic starts to break up a dozen times; birds circle back over field; then off again in another panic even before they start to land. This goes on for at least 15 minutes. Finally, by 7:25, several hundred of them have landed in a flock on water, where they seem to be relaxing, and a few have landed on the rocks and are relaxing too.

Hundreds of other birds, however, form flocks in air, circle very high in air, and then start to drift northwestward, with [[many?]] interspersed periods of circling and at least one Silent Panic very high in air. [[underlined]] Then birds are presumably going to a colony [[/underlined]] 

It was very noticeable that each tune the Silent Panic started to break up there was a terrific burst of LCN's (rattle undertone) by the birds I have also heard the same notes after many other panics 

One bird, flying rather high, far away from me, gave a complete aerial L.C. during one of the periods of semi-relaxation The usual posture - with beating wings

One bird flew up when the others first panicked; but, before joining the others in their escape, flew about thirty yards, very fast, with deep wing-beats, did moderately shallow swoop, with beating wings, [[image - small sketch of bird swooping]], and then soared upward with motionless wings. This bird uttered four or five, rather long-drawn, plaintive, "Wah" or "Waaaaaah" notes, during the accelerated horizontal flight and the subsequent swoop. In other words, [[underlined]] this pattern was just like the swoop & PCC [[image - arrow pointing right]] soar pattern of the Ring-belted gull![[/underlined]]!!
