(413) it. The fly appeared to be about 1/8 inch long(3 mm.). This is a small one. I could not see that its wings were mottled. (Ref. Dr. Linsdale). On this occasion the thrasher talk was different from that heard at 9--9:30. Ant carrying. At about 12 O'clock,as Brownie sat on my knee, an Argentine ant crawled down from underneath her feathers, walked down her leg on to my clothes. This illustrates one method by which these insects may be disseminated. The bird did not seem aware of its presence. She introduced a new feature into her undersong--a miniature xylophone effect. This is a modification of the"bell song" produced by uttering with great rapidity a single note pitched the same as the first "teen" or "ting" of the bell song and of the same timbre. It is uttered so rapidly as to give the effect of a sustained vibrating sound as in the xylophone. I have heard something approaching this the first note of a somewhat before where^the bell song^noted at the time was not single. In the present case, the regular teen-tong follows the sustained succession of short notes. ANNIVERSARY of B&G This is the anniversary of Brownie and Greenie's first being seen together at the feeding station provided for them to keep them from digging up the oval lawn . 4 to 4:30 Greenie was alone in the glade unembarrassed by the presence of Brownie. He sang about half-song practically all of this time, at times approaching three-quarter. There were few imitations. These are mostly in the three-quarter song. He did, however imitate the hen and the thrush. I was away until about 5:45. Night Roost. At 6:00 nobody was in either Brownie's or Greenie's tree, and no thrashers were in sight. About 6:05 a thrasher was seen to climb up into the sparrow-hawk pine.
