1939 A group of seven N. Phalaropes was seen; Avocets numbered close to 40 and we saw three young, feeding along the shore of a mud dyke, which later floated off on the surface of the water. They were about one third grown, covered with grey down. Another three (floating) were very small and when I got out of the car (trying to see the sandpipers) the adults became very much excited (which frightened the sandpipers away). One Avocet crouched, and dragged its wings, lowered its head and acted as a cat does when preparing to pounce on its prey. The usual Caspian Terns were seen, and also a group of Least Terns (10-12) feeding over a salt pool. Both adults and immatures were seen. We gave the kit-tic call. Also that eye was partly surrounded by white. This in addition to small size made me quite sure they were Least Terns. The tail was just as pictured in Hoffmann. They were apparently picking up insects as they did not plunge into the water. There were about 40 willets with the Avocets (total 80+) July 8. We returned to Sempre Verde on Saturday afternoon and stopped at Drumbaron Bridge and Mt. View Marsh on the way. At the bridge we saw even more Avocets
