common throughout the autumn stay. In 1918, 

 present in limited numbers from May 6 to May 23 

 and rather more numerous Sept. 1 7 to 30. Of those 

 in adult plumage, two males (May 13, 1918 and 

 Sept. 20, 1917) have the white loral line continuous 

 to bill and can therefore be ascribed to Z. I. gambeli. 

 The other has it faintly interrupted across the lores 

 and must therefore be regarded as intermediate be- 

 tween Z. I. leucophrys and gambeli. 



150. white-throated sparrow, Zonotrichia 



albicolUs. 

 Common both spring and autumn. In 1918, 

 absent from May 27 to Sept. 8, except four in- 

 dividuals seen on July 24. Great numbers seen 

 Sept. 19-27, but still present when Young de- 

 parted on Oct. 2. 



151. *TREE SPARROW, Spizella monticola. 



Not noted in 1917. In 1918 observed Iron: April 

 26 to May 4, and again on Oct. 1 and 2. One 

 specimen, female, April 30, I refer to 5. m. 

 monticola. 

 1 52. ^CHIPPING SPARROW, Spizella passehna. 



Very common in the spring of 1917. To the 

 end of May flocks of a hundred or more were met. 

 In the autumn the species was not certainly identi- 

 fied though the first day of arrival I thought I 

 recognized them amongst the hordes of clay-colored 

 sparrows. In 1918, Young noted a few on May 

 4 and 8. From the 16th to 27th it was present 

 in flocks of from 50 to 100. The species departed 

 on June 8 and no more were seen except 3 on July 



23. 



153. ^CLAY-COLORED SPARROW, Spizella pallida. 

 Very common in spring and autumn. In 1917, 



they seemed to leave on Sept. 21, but in 1918, 

 Young noted them to the date of leaving on Oct. 2. 



154. ^SLATE-COLORED JUNCO, Junco h^emalis. 



In 1917, but one specimen seen in the spring but 

 fairly common in the autumn. In 1918, Young 

 noted it from April 24 to May 1 5 and from Sept. 

 6 to Oct. 2. 



155. *SONG SPARROW, Melospiza melodia. 

 Common in spring and autumn of both years. In 



1918, present on arrival, April 24, and when leav- 

 ing, Oct. 2. Specimens taken between May 13 and 

 July 31, probably breeding birds are the slightly 

 lighter form, with more distinct markings, than 

 eastern M. m. melodia and I refer them to M. m. 

 juddi. 



156. ^Lincoln's sparrow, Melospiza lincolni. 



In 1917, single individuals seen and taken on 

 May 19 and June 1. In the autumn seen nearly 

 daily in limited numbers. Noted in limited numbers 

 by Young in 1918 from May 11 to 25 and more 

 commonly from Aug 3 to Oct. 1. 



157. *SWAMP sparrow, Melospiza georgiana. 

 Seen in small numbers in the spring of 1917 and 



more commonly in the autumn. In 1918, Young 

 noted it from May 4 to 30 and again Aug. 21 to 

 Oct. 2. Strangely enough but one bird was seen 

 in the summer, June 10, which seems to indicate 

 that the species does not breed in the locality. 



158. %0X SPARROW, Passerella iliaca. 



One specimen taken Sept. 22 is all that was seen 

 in 1917. In 1918, Young noted single individuals 

 on Sept. 16, 24 and 30, and a flock of 30 on the 

 25th. 

 1 59. ^TowHEE, Pipilo eryihropthalmus. 



In 1917, fairly common in the spring and still 

 present Sept. 19 and 21. In 1918, Young saw a 

 few individuals with general regularity from May 

 24 to July 29. A single bird, Aug. 13, and another 

 Sept. 19. 



160. ^ROSE-BREASTED GROSBEAK, Zamelodia 



ludoviciana. 

 Fairly common during the spring visit in 1917. 

 In 1918 observed irregularly from May 16 to 

 Aug. 5. 



161. ^PURPLE MARTIN, Progne subis. 



A few seen daily in 1917, probably the same 

 ones. A few occupied a box near an adjoining 

 summer cottage and another colony was found nest- 

 ing according to aboriginal habit in a hollow tree 

 a few miles from camp. In 1918, noted by Young 

 from May 17 to Sept. 20. 



162. *CLIFF SWALLOW, Peirochelidon lunifrom. 



In 1917 a few seen daily with the flocks of Barn 

 Swallows about camp and occasional birds else- 

 where. Seton noted twenty-five nests on a barn in 

 1891. In 1918, noted from May 24 to Sept. 17. 



163. ''^BARN SWALLOW, Hitundo erylhroga&ier. 

 Small colonies occupy most of the farm building 



groups in the neighborhood. In the autumn of 1917 

 this was the only swallow seen. In the chilly morn- 

 ings a small flock of them would be found warming 

 themselves on the sunny roof of the house where the 

 frost was melting. As soon as the day warmed 

 they disappeared over the meadows and rarely re- 

 turned until the next morning. The last seen were 

 on Sept. 21. In 1918, they remained common until 

 Sept. 20. 



1 64. *TREE SWALLOW, IridopTocne bicolor. 



In 1917, only a few seen each day in spring and 

 none in the autumn. In 1918, they remained com- 

 mon until Aug. 21, but a few were seen thereafter 

 until Sept. 1 7. 



165. *BANK SWALLOW, Riparia riparia. 



A few observed daily in the spring of 1917. The 

 Ward brothers say that one stage of the lake left 

 numerous steep banks five to six feet high and that 

 swallows nested in these in great numbers. Now
