42. Riparia riparia. Bank Swallow. A single bird taken from a small flock 
of other swallows September 19, 1907, was the only one noted. 
43. Vireosylva olivacea. Red-eyed Vireo. This was the commonest of all 
the vireos, and was found in the timber everywhere. Great numbers of them were 
mixt in with the migrating flocks of warblers, and they also past thru the trees 
above camp. They gave their usual call note frequently, and it was possible to 
trace them up by that, as they were not at all wild. This is a common breeding- 
species here. 
44. Vireosylva gilva gilva. Warbling Vireo. This species was fairly com- 
mon both seasons, and several were taken, mostly in the heavier timber. So far as 
noticed they were silent, and were found with the migrating flocks of warblers. 
45. Lanivireo solitarius solitarius. Blue-headed Vireo. Three specimens of 
this bird were taken, and this is the first time that I have noted it personally in 
Kansas. They are probably a regular but rare migrant, occurring along the 
streams. Two of our birds were taken in 1907, and one the year following. 
46. Vireo griseus griseus. White-eyed Vireo. This bird was found in the 
dense thickets on the hillsides, and was very hard to locate. We heard their notes 
and songs on every visit to these localities, but the birds themselves remained so 
well hidden, that we succeeded in getting them only after long watching. 
47. Vireo bellii bellii. Bell Vireo. There were a few of these birds in the 
thickets on the brushy hillsides during 1908, but they were shy and hard to locate. 
Only one was taken, on September 15, 1908; but we heard their notes and an 
occasional song nearly every day. 
48. Mniotilta varia. Black-and- White Warbler. One adult male taken 
September 14, 1908, from a flock of migrating warblers, and none others seen. 
49. Vermivora rubricapilla rubricapilla. Nashville Warbler. This is a regu- 
lar tho rare migrant in this vicinity. We found them during 1908, in the dense 
brush and tangled grape-vines along Hasty Creek, where they could be secured 
only by patient watching. They were very quick and active, and usually when 
seen were too close to shoot without entirely destroying them. 
50. Vermivora celata celata. Orange-crowned Warbler. One taken Septem- 
ber 14, 1908. The fall migration is rather a poor time for warblers in this vicinity, 
and only a few scattered examples of most of the species were observed. 
51. Compsothlypis americana ramalinae. Western Parula Warbler. Found 
in the heavy bottom timber along Washington Creek. Several specimens of this 
small warbler were secured from flocks of migrants, and more were seen on both 
years. 
52. Dendroica aestiva aestiva. Yellow Warbler. One taken September 20, 
1907, from a flock of other migrating Warblers and Vireos. 
53. Dendroica virens. Black-throated Green Warbler. One bird taken 
September 16, 1908, from a small flock of warblers in the trees above camp. This 
bird appears to be of regular tho rare occurrence, during both spring and fall 
migrations. 
54. Seiurus aurocapillus. Ovenbird. One taken from a considerable flock of 
warblers September 14, 1908, was the only one seen. The breeding birds had all 
left for the south. 
55. Oporornis agilis. Connecticut Warbler. One taken September 14, 1908, 
in a brushy thicket near camp where it was in company with numerous other 
warblers. This bird is rather rare in this vicinity, and but few specimens have 
been taken. 
56. Geothlypis trichas brachydactyla. Northern Yellowthroat. All of these
