to either of these places this road is gaining favor with him, despite the fact that, to the latter it is much longer and more indirect. Food of the young thrashers. On the advice of Mr. Brock I have added to the menu of Okii and Chiisai a custard of egg, milk, butter and a little salt. On my own initiative I have added cod-liver oil (containing vita- mns A and D) to both the custard and the soft-food. They also are given a few meal-worms about every third feeding. Also begin- ing today, as the notes indicate, they will be allowed direct sunshine (with choice of shade) in addition to that that comes through the window glass. All this ought to keep them from becomig rickety! At their bedtime, for the first time, they were disturbed and inclined to complain about matters. Principally, I think, because O, also for the first time, persistently sought a non- existent high roosting place in the cage and climbed about rest- lessly setting a bad example for C. While it was obvious that he wanted a higher roost, I made a crude experiment by placing him on my lap. He immediately climbed to my shoulder and seemed contented there. This, however, could not be considered a satisfactory solution of the roosting problem, so he was returned to the cage. He continued to climb and scramble. The cage was then darkened. This did not work: both continued to move about. I did not an- ticipate this result, as all birds of my acquaintance invariably quiet down when the cage is covered. I removed the cover and dark- ened the room as much as possible by drawing all the curtains to shut out the daylight. No good. On the theory that they were now unable to see any of the perches clearly and that this (plus ex- citement perhaps) was now their trouble, I turned on all of the lights in the room, still keeping out the daylight. They quickly found perches and thenceforth there was not a sound from them-- whatever theory applies. The lights were then turned off, one side of the cage (that toward the room) being left uncovered. 8:30 P.M. I find they have not moved and inch, and have just completely covered the cage. Revival of thrasher song For several weeks there has been little thrasher song in this neighborhood until the last few days: Birds busy with broods and Brownie gone. I predicted (to Mrs. Sampson) that after I took their youngsters, their thrashers would begin to sing again very soon. (Nothing anthropomorphic about that! Rather: ananthropo- morphic). Early this morning thrashers were singing loudly down at Sampsons'. I went down there about 11 and Mr. Sampson said they had been "singing their heads off all morning"--for the first time in weeks. 3 or 4 days ago a thrasher that was singing frequently just west of the west fence earlier in the season and then was not heard often during the following weeks, began to sing again. Today he was at it "all the time" and even came to this garden and sang. He was still at it at 7:25 P.M. (Sunset 7:18). I have thought that he had adopted the west lot as his territory and nested there, but have never investigated. Perhaps he has, and his brood is now off the nest and/or a new nest is in prospect--hence the revival of song. Perhaps, also, he is investigating my place with a view to taking territorial possession. His song differs utterly from B's in phrasing and timbre. Not only is the individual thrasher versatile in song, but individuals differ markedly from each other. Yet they "all" seem to scrip, hrick, whip, or whatever it is, and say queclick or quilk in about the same way.
