LINCOLN'S SPARROW 1461 



Roy C. Anderson (1959) reports finding the air sacs of a Lincoln's 

 sparrow infested with the nematode Diplotriaena bargusinica. He 

 believes that in some cases this may be an important disease factor. 

 L. R. Penner (1939) reports a fluke, Tamerlania melospizae, from the 

 ureter of a Lincoln's sparrow found dead at Minneapolis May 1, 1938. 

 Joseph C. Bequaert (1954) lists the species as host to louse flies 

 (Hippoboscidae) of the following species: Ornithomyia fringillina and 

 Ornithoica vicina. G. Robert Coatney and Evaline West (1938) 

 write that the blood parasite Haemoproteus was found in a Lincoln's 

 sparrow collected near Peru, Nebr., in 1937: "but there were too few 

 to allow for detailed study." 



Fall. — We were never able to remain at Dorion until the Lincoln's 

 sparrows left for their autumn migration. When we departed Sept. 

 6, 1955, the birds were still active on their summer territories. Rita 

 Taylor, a resident of Dorion, wrote us: "We have had Lincoln's 

 sparrows feeding here quite often this fall, three at one time at the 

 kitchen window. The last one was Sept. 19." 



The peak of the autumn migration in the Toronto region is generally 

 in the third week of September, when they may be found in marshy 

 places and in weedy fields, often in company with white-throated and 

 white-crowned sparrows. We used to flush them from the former 

 Ashbridge's Bay marsh on the Toronto waterfront. They would 

 keep well in cover, usually but some would yield to curiosity long 

 enough to perch in some low bush, peek out at the observers with 

 craned necks, raised crest, and wide-eyed wonderment, then drop 

 down out of sight or dash away ahead to repeat the performance. 

 The latest Toronto record is Nov. 19, 1932 (Speirs, in litt.). 



Bird banders probably see more Lincoln's sparrows on migration 

 than most bird watchers. Ruth Brown, of Toronto, Ont., took them 

 on Sept. 22, 23, and 30 in 1956 at her city banding station. Two 

 banding recoveries are of interest to fall migration. One banded at 

 Wantagh, Long Island, N.Y. May 8, 1935, was recovered Oct. 1, 1935. 

 in Gaspe County, Quebec. Another banded at Treesbank, Manitoba, 

 Aug. 29, 1937, was recovered at Canarem, Iowa. Dec. 16, 1937. 



Roberts (1932) has an interesting account of the fall migration 

 through Minnesota: 



In the fall it is rather easier to find for then it is very abundant and keeps 

 company with the other migrating Sparrows, but it is still silent and much more 

 timid than its companions. Mr. Kendall finds it common on the Mesabi Iron 

 Range in the fall and speaks of its quiet ways and resemblance to the Song Spar- 

 row, especially when the spot on the breast is well marked. Dr. Hvoslef refers 

 frequently in his notes to its abundance at Lancsboro, in the valley of the Root 

 River, occasionally for a couple of weeks rivaling in numbers the White-throat. 

 It is often abundant in the vicinity of the Twin Cities in late September and early 

 October, frequenting hedgerows, weed-patches, borders of woods, tamarack
