Fulica Americana -41- June 2/ Jewel Lake, Tilden Park, Contra Costa Co, Calif. making a series of low notes resembling crowing. (Now 11:50) the ♂ has moved over to F9 and the ♀ has vanished on the nest (?) the ♂ was just seen to chase an insect into the cat-tails and jump out at the water to pick it off the leaves) They were out of sight for some time (now the ♀ is visible at 6:10) That's over an hour 65 min - that the eggs have not been incubated. Both birds are now in sight - the ♂ being beside the cat-tails near the nest) and then the ♀ appeared from the cat-tails some distance away. At 11:20, the ♂ made a lunge at an immature at I 6:11 - the young ducked & he churned twice. Awhile later, one of the largest young venturing into the gap near the nest, was promptly chased out by the female. The young seem to be constantly hunting the surface of the Potamogeton for insects - they completely ignore the many turtles lying with their heads above water - but make repeated attempts to catch skating dragon flies - they are noisy, giving a note that is a shrill "poont" like sound - right now (12m) one is 'whewring' but it's the first live heard today. The most dive seen in the 5 brood today seems to be 5. Both parents and the young seem to be eating mostly the Potamogeton, which is so dense they nearly have to walk over it. They do not seem to be eating cat-tail
