(403) when I went out there a little later, were not seen or heard. I did not see or hear them in Reynolds territory and they had not been heard there up to about 10. 10:45. I have not seen signs of either bird since 8:45. 11:40 While sitting here writing, undersong was heard nearby. I stepped out of the window on to the terrace and Greenie was eating suett at the upper station in the court. Brownie came quickly out from under the rhododendrons and jumped to my hand with little squeaks and gurgles. The top of her bill carried lumps of black mud on it, otherwise she was immaculate. Her plumage is perfect as far as can be seen. She was very hungry. Bill is opened and closed in undersong. 12:10 I have just been watching Greenie singing his under- song in the glade. He does open his bill in undersong. I had a close view of him in profile against the sky and his bill is constant ly opened and closed as evidenced by the streak of light seen between the upper and lower mandibles. I have wondered heretofore how these birds could articulate their phrases in undersong and produce such -out their melodious sounds with giving the effect of being "wire-drawn". Both sing at the same time. 2:45. I went to the glade at 2:00 to look up the thrashers. Brownie and Greenie were there about 20 feet apart and both began their undersongs almost at once, though they may have been singing before. They kept it up almost uninterruptedly for about two quarters of an hour. At one time Greenie imitated the thrush simultaneously with Brownie's imitation of the hen. Brownie sat on one of her favorite branches about a foot above the ground and a quail walked out quietly until it was almost underneath her. I said: "Chase the quail out, Brownie" and by coincidence, she decided to do so almost at that instant, making a thorough job of it. If one speaks to these birds often enough, making some sort of suggestion to them, it is rather surprising how often a pat response follows. Brownie now sits in my hand longer and more patiently while waiting for worms--if not very hungry. On such occasions she will often look for hawks, stretch her neck horizontally and look at some distant object or examine some portion of my topography. This time B. inspects my finger-nails. B. objects to quail too near.
