although she did make some show of driving them away. A little later I took position near the 4th nest and Brownie was very active in feeding the young with worms which she got from me, while Greenie was ranging farther afield. On one of Brownie's returns to the nest from one of her foraging expeditions, I called her over to me to see what she had in her bill (by showing her meal worms) and it proved to be a large cut-worm. From there I went to the glade, Cheeky and Cocky were the first to put in an appearance, the former beginning proceedings by landing on top of my hat (which was on my head). This attracted Cocky who came running up and crouched as if to fly up also; but Cheeky, who was having a good time up there pecking about, did not approve and made harsh noises at him, so to console Cocky, I gave him worms, Cheeky coming down to my lap for his share. During this period Cocky was seen to dash at something in a blossom of a Bee Plant (Scrophularia Californica) and back hastily away. He then pecked several times at some object that had been knocked to the ground, backing away hastily each time. It was seen to be a yellow- young jacket, which he eventually ate. How did this bird know that yellow- jackets are dangerous? Brownie then came, after the young birds had retired into the bushes, evidently looking for me, as she jumped up on me at once and searched for the worm supply, but it was temporarily exhausted. She could not believe the bad news for some time and alter- nated between the ground and my lap in her search, then up to a branch, where she scrutinized me from above. When this brought no results, she compromised by chasing into the chaparral one of the youngsters that had incautiously revealed himself. As noted, I have been trying to shift the feeding center for the adult birds to the vicinity of the oval lawn, 200 feet nearer nest No.4. Accordingly I got a new supply of worms and went there. Greenie, who has been very inconspic- ious the last few days, was the first to note the change and crept up
