the streaking more indefinite and obscure. The adult males 

 have the yellow on the primaries and rectrices very bright. 

 Compared with specimens taken in the fall in central Wiscon- 

 sin, the olive of the upper parts is darker, and below the 

 streaks are a little longer in these skins. Measurements ap- 

 pear to be the same. Fairly common, in flocks ranging from a 

 dozen to fifty. One morning I found an adult and an imma- 

 ture male sitting together in a bush, the former singing a 

 simple twittering song. In flocks they are rather silent, though 

 when startled their loud che-a is given. In town a flock of 

 about thirty fed every day in a vacant lot, paying no attention 

 to people on the sidewalks. They fed in close order, appar- 

 ently heedless of danger, and when startled usually flew a few 

 feet only. A favorite perch was a telephone-wire when they 

 were through feeding. The latter part of June I found them 

 feeding their young in the streets of Williams, but when I left, 

 in April, they had shown as yet no signs of mating. 



17. Passer domesticns (Linn). — English Sparrow. Not 

 noticed until the latter part of March, when a single male was 

 seen. There were a few around Flagstaff, twenty-five miles 

 east, and I think this one came from there. The evening be- 

 fore a freight had picked up two cars of stulls (timbers for the 

 mines) at Flagstaff after dark, and had set them out at Will- 

 iams. The next morning, just at daylight, I saw the sparrow 

 sitting on one of the cars calling, and got up to within a few 

 feet of it. It is possible that the bird had gone to roost in 

 these stulls the night before at Flagstaff, and had been carried 

 over in this way, though of course it could have flown the dis- 

 tance during the night. In June I saw a pair in the town, so 

 that the species had evidently gained a foothold there. 



18. Pooecetes gramineus con-finis Baird. — Western Vesper 

 Sparrow. Three adult males, March 17. One adult female, 

 March 29. Found in the open around the Crater lakes ; espe- 

 cially common on the east side of Rollins Lake, and a number 

 seen near a lake west of Crater Mountain. First seen March 

 17, and common from then on. This subspecies had the same 

 habits as the eastern bird. The only note I heard them give 

 was a faint tseet. They fed on the ground among the broken 

 rocks and were hard to flnd, but when forced to flight they 

 usually lit on a rock, so that they were easily taken. During 

 a heavy wind it was almost impossible to make them fly.
