One wonders, also, if the Road-runner's interest in this locality has any connection with thrasher eggs. At 2:05 the bird on the nest was unmistakably Nova with her great, soft eyes and large bill. on the nest, and At 3:20 it was Brownie, who a little later came running to me at the oval lawn from 100 feet away with wabbling tail, seemingly about to topple him over sideways. (Two minutes before, the road-run- ner had preceded me along the same road, pausing to take backward looks at me. Inviting me to feed him?) Brownie came for worms, then dug about 6 cut-worms out of the lawn, then back to me for more worms, then off down the road toward the nest with a billful for his mate. He was never so attentive to Greenie. Thus far today the nest has not been seen unoccupied. The situation begins to look favorable. 7P.M. There has been a bird in the nest all day. At 7:15 I went out to note what disposition the thrashers were going to make for the night; reasoning that, if B did not go to his regular roost, then, as I suspected to be the case based on today's behavior, there should be one egg in the nest, since B, as noted in connection with nest 5, takes the night shift on the nest. B was in the glade and Nova was in the nest. I stationed myself about midway. B came for worms, then went down into the glade and disappeared. Soon he began to sing the Russet-backed Thrush song. I told Julio, who was watching, that he was calling for his mate to come to him and take her night roost so that he could take over the night shift.

As they were talking it over, I hastened to the nest and had just had time to feel one egg when B popped into it. So, after all, the speculation as to what might be taking place down in the canyon these last few days, Brownie's
