Fulica americana -527 me 27 Lake Temescal, 420 ft., Alameda Co., Calif. - started on the E side, I am not sure. This beginning base is composed mostly plog wet and dry pieces of narrow-leaved cat-tail (both species are in the surrounding vegetation tho the rest is in broad-leaved). There seem to be few if any stems worked in. First the male splatted up to defend then the ♀ replaced him and he went back to care for 2 couple of young. A new platform is located in the @ 22 clump, it looks like a display or copulatory platform just a loose aggregation of cat-tail stems, both old and new. There may be only 2 lynq left in the E wood. -When I came in this morning O was seen feeding in the S bay, both tags on and in good shape. One egg in nest K 7.17-some kids were nearly so I didn't investigate further. What may have been destored to be a display platform was at K 7.13-also some stray cat-tails at K 9.3. Neither K nor trids showed any great concern about this nest. A well built platform at L 4.3-well used, must be a display affair. It is flat, about 1/2 inches above the water all wet composed of long dried cat-tail leaves, [illegible] mostly narrow-leaved. A little green stuff laid in, it is about 1 foot in diameter, and nearly round. The ♂ "julgued" at me all the while as I examined this structure.
