March 14th. Except for an occasional full song early in the morning when now he happens to be off duty, B is very silent, not even talking to me when he comes for worms. Changes of shift, contrary to ex- petation and to previous observations, is now usually made without preliminary sound by either bird. Rhody continued to wander about the place restlessly with quiescent periods of a few minutes to an hour at a time, searching and scanning the surroundings, though much less vocal than yester- day. He also played with the mIRROR again. At the present time there are three kinds of humming birds at this place: Anna (resident), Allen (regular summer visitant) and Rufous (migrant) now passing through. A gorgeous Rufous, like a living flame, was frequently in a blossoming flowering crab-apple. March 15th. Brownie sang full song very early at the Scamell's where he went to exchange songs with the Sampson thrasher. Rhody began his calling also about sunrise. About 9:30 he came to me for something to eat and sang his regular song repeatedly at arm's length, singing "between worms". This song is quite resonant at close quarters; he works hard to get it out. The first few coos at least, are definite coos begin- ing with a positive k sound. Some of the following ones, especially the last one, which fades out and flattens, may not begin with a k. Almost invariably there are 6, 7, or 8 coos. His wing-clapping gesture continues to be used occasionally. So far it has consisted of two to four powerful beats, say, one too two seconds apart. Before making each he "gathers" for the effort by spreading his wings horizontally or by trailing them at to his sides, lowering his head at each as if devote all of his energy to the beat. The sound emitted is "flup!" Rufous hum- mer here.
