Journal R.E.Johnson 1968 Nov. 30 Berkeley Aquatic Park, Alameda Co., Calif. Overcast, sprinkling early, increasing to heavy rain by 3:20 P.M. Total observation period: 1:00 - 4:30 PM. The park has changed considerably since I was an undergraduate student at UC (1955-59). At that time there was more cover for birds than at present. The weeds along most of the flats near the shore line are now controlled. The island was once a jungle to paradise for birds. Now it is cleared & there is a bridge to it. The shrubbery has been pruned back considerably all along both sides of the lake leaving few hiding places for secretive birds. Speed boats & water skiers race back & forth down the lake preventing use of much of the lake by waterbirds. Sandpipers & ducks fly in from San Francisco Bay when boats are still on the lake. The lake is 1 1/2 miles long (running N + south), & parallels the Freeway [Interstate 80] which separates it from the bay. It is surrounded by a narrow band of evergreen ornamental shrubs. Species seen include: Pied-billed Grebe - 6 (species account) Arctic Loon - 1 Brown Pelican - 2 Snowy Egret - 3 (species account) American Egret - 1 Green Heron - 1 (flies across lake & lands 15 ft up in cedar) Common Goldeneye - 6 ♀ Bufflehead - 2
