Aug 15 Jewel Lake, 510 ft., Contra Costa Co., Calif. Green added since the last egg hatched. The brood nests at N25.18 seems to still be in size and in good repair. The old nest at N25.24 is long out of use. 10:30 - The F is feeding one young still covered with cloud plumes, hence only 1-2-3 days old. The E is in the nest area but whether or not she has a young I don't know. I'm certain of only 1 ymg. Lake Temescal, 420 ft., Alameda Co., Calif. The SE pair have a brood nest at F7.13 - their most recent ymg is not around and only the well developed immature surviving from their 2nd clutch is. That bird seems to be fully tolerated close to the adults and in the core area. Found egg of their third clutch floating near the new brood nest. Only one ymg is surviving in the 2nd brood of the E pair. The P16.2 nest is in repair and use, the P15.3 nest is abandoned, a well developed nest is at P16.4 and a great new structure at P23.9. Nothing in the Q 22 clump. At least one ymg still seems to be accompanying a SW adult, feeding with it but not necessarily being fed by it. Nothing seems to me general in all cools now so the frequent changes are made with the use of wings. 4:40 p.m.
