Maclean 1965 C. fuscicollis marsh very high - all very close together and all displaying. Continues for at least 200 m. until ground obscured, then saw one veer off toward South, other two continue on to East. 4 July Saw very similar behavior in same area. Three birds very high, W-E, with much display heard. At least 2 and probably three uses V-wing hover ☺ Joined by another bird which also uses hover. Split up somewhat just as they disappeared - could not tell how. Could be beginning of association of ♂♂ preparatory to migration. Birds are obviously not terrestrial strongly, but display indicates sexual activity too great for flocking.
