7. CULLION 1950 Fulica Americana -3/10- Apr 17 Cele Temescal, 422 ft, Alameda Co, Calif. The platform at H.7.25 has a considerable accumulation of material both green and dead but is not taking the shape of a nest. nest I6.1 This SW pair showed interest in defending this area for the first time today. The M went out into the open water but looked as if he was seriously considering churning, while the F remained in the cat-tails, close by, until the last minute, spooning. Walking along the W side I ceased out birds, perhaps all non-territorial. w15E and E were among them. As they drifted out towards K17, G/R came out from O14, moving to L16, and maintaining an aggressive position, deflected the flock back towards I13. After they were deflected, without actually attacking any, he crowed twice. Now 3:45 p.m. G/R is back at O14 with an UNM bird. Potamogeton is beginning to show up as an important part of the diet. That is, many birds are eating for it frequently. M
