Gymnogyps californianus 18 January 1946 San Francisco, Cal. seen nearly on the next trip. The youngster was found dead & considerably consumed by carnivores (?) on Oct. 21. Carcass located at back of cave within inches of where egg was found. Scats were so collected in cave & given to Dr. Benson but so far unidentified. Parasites from carcass were given to Dr. Herman (sp.?) of Fish & Game Comm. (Strawberry Canyon) - he believed them all to be post mortem. The only parasites observed on the birds during life were midge ones which hid among the feathers. No bones were collected from cave floor tho photos seem to show some. Photos show the nest usual scats in the cave too. The day adult caught, chick was found drenched with pre-digested food. Adult regurg- itated "about a pint" of this too but it was too far gone for identification. Adult was not heard to utter a sound. Chick gave the ugh ugh sounds often. Chick was banded twice - once with an eagle band & later with a silver band spec- cially made & engraved by Grant Bros. Tarsus of chick was larger than adult. It was the impression of Nell & others that the adult was quite lean & light - about 16 lbs. The
