Thrasher Nesting Cycle. In the following table only the beginning of the cycle for the three years is noted. The start of the first nest for the year is taken to be the date on which nesting activities have ceased to partake of random character (which may have extended over a period of several months) and have become coordinated and concentrated upon one structure. The fact that in this year's cycle the first set of eggs was laid in nest 90, which was started in Sept. 1934, instead of nest 10, which was started in Jan. 1935, is ignored in this table, though not in fact. The cycle is also based on Brownie's activities, as the head of the family. Thus although the second of 1934 was with a new mate, Nova, and it may have been her first for the year, it was, nevertheless, B's second; so she does not appear until she becomes the layer of the first egg. Again, the table does not show, what appears to be the fact, that as far as the male is concerned, the nesting period is "all the time".

He carried it into the dining room after pausing at the open window swinging his tail horizontally, i.e. wagging it sidewise like a dog, at the rate of about ten wags in 5 seconds. This is a new Lizard carry-gesture. He came out in a few minutes and went to the south window of the dining room and tapped the glass with the animal still in his bill. Next followed a stroll about the garden and a repetition of the window tapping. The impression gained was that he had seen his reflection from the inside and had gone around to the outside to look at the "other road-runner" and found that he was nowlin+ side, because he tried to jump up on the glass when outside. Upward flight. He next flew upward about ten feet to the low part of the roof and tapped on a bathroom window still with the lizard. He moved to the parapet of a balcony and from there flew upward again to the main roof, remaining there for perhaps three quarters of an hour or more, calling but never dropping the lizard. Next he flew down almost vertically to a point near where I sat making an easy and graceful Easy landing.
