Fulica Americana 489 eve 10 Jewel Lake, 510 ft. Contra Costa Co., Calif- calling the O's to give a series of the low "punks" that are given in such occasions. They were moving down from the H17 area. A couple of these young have very dark bills. One of the older yng has my light gray below the water line, its breast being the same color as its back, only the frontal area above the water being a light gray. 1:02 p.m. - Both adults are out feeding on the S pool, one at G8, the other D-144. I have not seen these yng being fed by the parents for several days. The oldest of these yng is still younger than the immature seen @ on Middle Chain Lake in Golden Gate Park on June 7. Also the yng feed and move quite independently of the adults, still they quickly heed warnings by the adults. Just now I dropped my pen, as I reached down to pick it up, the white pages of this notebook attracted the O's attention. he gave several low "punks" and the yng in its vicinity rather quickly responded. This low warning note of the male is remarkably similar to the low & "punk" I am confused by it quite frequently, tho it doesn't really have the nasal quality of the & when it is heard alone it seems tricky. This is probably the only call in which there is overlap. 1:14 p.m. tho O chased the & into the cattails
