160 THE CONDOR VoL. XI 26. Nuttallornis b0realis. Olive-sided Flycatcher. One bird taken each of the two years. They were silent, and were found on the edge of the timber in one of the draws near c.amp. This species appears to be a rare spring and fall migrant, in the vicinity of Lawrence. 27. Myiochanes virens. Wood Pewee. These birds were fairly common in the bottom lands along Washington Creek, and several specimens, principally in immature plumage, were taken. 28. Empidonax fiaviventris. Yellow-bellied Flycatcher. One immature female taken September 14, 1908. These birds are rare migrants here, and I have always found them in the draws in the edge of the hills. 29. Empidonax virescens. Acadian Flycatcher. One taken September 15, 1908, was the only one noted. The time of the year, however, was rather unfavor- able for the flycatchers, and only a small number of each of the other species was observed. 30. Empidonax traillii alnorum. Alder Flycatcher. One immature female, taken September 15, 1908, was the only one noted. 31. Empidonax rainlinus. Least Flycatcher. Two of these little flycatchers were taken in the draw back of camp. In the afternoons towards evening, these, and the other species of Empidonax found, were feeding in this draw, when every- thing was still, except for the shrilling of the cicadas. The flycatchers would fly a few feet, making an audible flutter with their wings, and then perching, remain still for perhaps five or ten minutes, so that it was very hard work to locate them.' This probably accounts for the small humber taken. 32. Cyanocitta cristata cristata. Blue Jay. Very common, both in the timber along the creek bottoms, and in the oaks along the side-Hills. A large series of these birds was taken as the stomachs were wanted to determine the food habits. They were nearly all in very poor plumage, especially about the head. Some, however, were in perfect fall dress, and were very handsome. Around camp we found them shy; but in the mornings when we had gone, they always came down to investigate, and probably to pick up food among the camp refuse. In the timber, they were feeding upon acorns and. ground beetles. All those taken the second year, were in much better plumage than the year before, showing that the season was farther advanced. 33. Corvus brachyrhynchos brachyrhynchos. American Crow. Crows were common everywhere. The side-hills and draws near camp are favorite nesting places with them in spring, and young crows were seen and heard continually. Most of them were in very poor plumage, and we only made eight skins. One morning I shot a?crow on the wing, as it flew high over camp, and for the rest of the day, seven or eight of the birds lingered around the point of a hill, a short dis- tance away, cawing and watching, as if wondering what had become of their companion. 34. Quiscalus quiscula aeneus. Bronzed Grackle. In Lawrence there is a large grackle roost to which the birds begin to resort in July, and.by September are fully assembled. In the morning they start out in long lines over the country, in search of feeding grounds, and the vicinity of our camp, especially during the fall of 1908 was a favorite place with them. They usually came in about eight in in the morning, and .began the return flight about five in the afternoon. First we would see a few straggling flocks coming in from the northeast, and following these a long black line, undulating and twisting, always following the exact turns made by those in the lead, but preserving, on the whole, a straight course. They usually alighted in some dump of trees, and poured in until the limbs were black,
