taking worms dropped two feet away, digging there between worms, Brown-eyes, meanwhile, steadily eating soft-food from my hand. They both picked up plant fibre and dropped it near me, not going to the nest at all. I may imagine it, but Green-eyes may have the flatter head). The talk of both of them was rather deeper toned than usual and suggestive of the opening notes of full song. (Wrens are gathering nesting material and tapping in a pile of boxes underneath the pine tree at the east end of the lath house). Feb. 27th. 8 A.M. Neither thrasher in sight. They finally appeared for food, gathered a few fibres. Brown-eyes posed for her picture near the south side of the glade; Green-eyes ditto at side-walk level below the chaparral. (See h. 23A) 10:30. (While feeding the thrashers on the bank across the road north of the glade, I noticed Bush-tits building a nest in a black acacia (Acacia Melanoxylon) about 20 feet from the thrasher nest. 11:00. One thrasher in the nest "doing nothing". 1:30 P.M. They seem to pay little attention to the nest now, yet when I just fed them, they gathered up a few almost invisible fibres and carried them to the nest. Their talk changes from time to time. For a day or so they will make mostly low warbling sounds--or it may be for only an hour or so. Yesterday it was verging upon typical deep phrases used in full song. Today it is a sort of plain- tive whine. They both seem to change at the same time. This refers both to their talk to each other and to me. This time I could see no difference in the flatness of their heads, when seen at arm's length at the same time. Difference in eye color is distinct. Green-eyes' head may be a little wider. He remains shy and will not now eat from my hand. He is more confident when his mate is near.
