one of them would be occupying it. So that their long absences during the day do not necessarily mean that the nest that B built is abandoned. Possibly, if Nova is an old bird, she needs time to work up another batch of eggs. I have been depending upon Brownie, around whom all thrasher activ- ities at this place have heretofore revolved, to be the principal factor in the anticipated taming of Nova--a sort of catalyst--just as he was with Greenie and all the youngsters; but the contumacious Nova is too hard-boiled, it seems, to be affected by his example. May 28th. Monday begins auspiciously, though overcast: Early song. Brownie favored us with early morning song. B in nest. At 9:00 A.M. he was sitting quietly in the nest, and at the same R.R. sizes me/me, the roadrunner approached along the driveway, took a good look up. at me, then retired without haste into the bushes. At 9:15, :35 and 58 there was still a thrasher in the nest. I think one of the times it was Nova, but can not be sure. At last observation time there was no sign of the bird's leaving. This is the longest observed sitting period in this particular nest to date. At 12:20, after my being absent since last observation, Brownie was sitting in the nest as if he never intended to leave. It begins to look like business. At 1:25, as I passed the nest stalking a ground squirrel, a thrasher was seen sitting in it quietly. As I passed around to the other tside, Rhody (the road-runner) slipped out into the open, paused to have a good look at me then, then disappeared. Almost simultaneously Brownie climbed to the nest with a Jerusalem cricket--certainly he is attentive to this wife of his. I waited a few moments, then approached the nest to find Brownie dozing in it comfortably, his mate having slipped out unseen by me. I suppose this bird to be Nova, but am not certain.
