(306) to see if he intended to do any more feeding, and he came promptly, took it to the young bird and rammed it down its throat. He did this with several more, then retired four feet to my right and sunned him- sself. The young bird then came to the food dish in front of me and ate, then sat on the water dish playing with the bubbles and drinking for several minutes, after having a "sun-fit". While he fussed with the water a purple finch came and sprawled out into a prolonged sun- fit only one foot behind him. Snooty looked at him, but ignored him for some time finally turning and going toward the finch quickly. The finch flew off and Snooty examined the ground carefully where it had been. He seemed to be actuated only by curiosity. In the meantime Greenie had left, going in the direction from which Brownie's under- song could be heard. Snooty retired to the same branch as before and preened. I had a good opportunity to compare Greenie and Snooty. Their eyes appear identical in color.
