been seen during the last week or so, Brownie can usually be found in the neighborhood of the nest. On the 23rd. still pictures were taken of Rhody drying him- sself between showers. (P.1119 A). He was not heard to sing when it was actually raining. On the same day he appeared at the cage at 9 A.M. bearing a lizard and wagging his tail sideways--the first appearance here this year of this courting procedure. I was hoping that he would offer it to one of the youngsters, or do something that would indicate that they were considered as possible candidates and, perhaps, at the same time throw some light upon the sexes of the two. While he stood facing them outside the wire, wagging his tail, he made no definite offer, and few minutes later, when on top of the cage, made no further advances. When he wandered off I followed for 30 minutes, finally leav- ing him still in possession on the lot to the west. On leaving he went down the lower road, occasionally stopping in front of some clump of shrubbery, facing it and repeating the tail wagging. At one place he also rattle-boomed softly as if there he had at last found something, but he passed on to the Scamells', went up on their porch to the dining room windows, watched his reflection and wagged his tail. He then tried to get in through the window, but gave it up. Next he proceeded to "offer" the lizard in the same way to a motor-car standing in front . Gave that up, tried various other places; came back to the car; then to where Mrs. Scamell and I were standing, repeating, and so on until I left him. There can be little doubt, bearing in mind last year's obser- vations also, that this carrying of food (especially lizards) about while searching for a mate is a definite part of courtship, and the food is intended as an offering. February 26th. Rhody appeared at the cage about 9 A.M. not carrying anything. He "studied" the youngsters longer than usual and made a few short dashes at them--but he does this for the benefit of the mag- pies also, so probably no significance attaches to the performance. Photometric Observations on Young Roadrunners Clear, bright and warm with no obsuring of the sun at any time during the day. Set-up consisted of a Weston Photronic Exposure meter, a thermo- eter (uncalibrated) and a sheet of white paper(Eaton's Souvenir Bond) mounted on a stand and directly opposed to the sun's rays. The thermometer was hung under shade upon the wire at the south side of the cage. Due, the exposure of the cage fully to the south and its northern side being entirely enclosed, temperatures within it are higher than the usual run of outside temperatures. The reading of the meter varies somewhat depending upon the angular relationship of the sun-paper-meter configuration. At the beginning there was time-lag (excessive) in the tem- perature readings on account of the thermometer's having been brought from a room where the temp. was only about 60. In the following where light is followed by a figure, unless otherwise stated, the meaning is that the intensity of light re-
