swamps, and similar dense coverts. Dr. Guilford found many at Lac qui Parle 

 Lake, Chippewa County, early in October, feeding on the mud-flats just outside 

 of the grass where the lake had dried; when flushed they took refuge in the grass 

 farther back. From September 25 to October 3, 1907, the writer found it abun- 

 dant at Heron Lake, Jackson County, frequenting thick, tangled weeds and grass 

 on low places and also keeping company with Harris's Sparrows and White- 

 throats in high brushy and weedy places and plum thickets. It was common in 

 corn-fields and old grass-grown gardens. It was sprightly and quick in its actions, 

 never still, twitching and jerking all the time, and timidly inquisitive. When 

 flushed in the open it flew low in the same halting manner and with the same 

 pumping of the tail as the Song Sparrow. When excited it erected the feathers 

 of the crown to form a noticeable topknot. No sounds were heard from it except 

 an occasion weak tsup. 



William A. Squires (1952) gives the latest record for New Brunswick 

 as a specimen in the American Museum taken on the Tobique River 

 Sept. 28, 1894. For Maine Ralph S. Palmer (1949) writes: "As birds 

 have been seen or collected in late August at places where they do not 

 breed, there is some wandering or migration by then. A definite 

 southward movement begins by the second week in September, with 

 most birds seen from September 24 to October 13. * * * Late dates 

 are: * * * October 17, 1918, on Monhegan (Wentworth in Jenney, 

 1919: 29)." Griscom and Snyder (1955) give autumn dates for Mas- 

 sachusetts as "September 12 (specimen) — October (November 1)." 

 Norman A. Wood (1951) says that in Michigan: "The fall migration, 

 for which the records are more numerous than for the spring, occurs 

 mainly between the last of August and early October." The latest 

 record for the Upper Peninsula is a report by Oscar M. Bryens (1939) 

 near McMillan in Luce County, on October 17, 1937. The latest 

 record for the Lower Peninsula appears to be one banded by E. M. 

 Brigham, Jr. on October 17, 1938 (Walkinshaw, 1939). In central 

 Pennsylvania Merrill Wood (1958) describes the Lincoln's sparrow as 

 "fall transient from early-September to late-October." 



Frances Westman (1960) records 7 Lincoln's sparrows among the 

 936 birds killed during four late September nights at the Barrie, 

 Ontario, television tower. This indicates that Lincoln's sparrow is a 

 night migrant. 



Winter. — Griscom (1932) writes of the Lincoln's sparrow in Guate- 

 mala as "A not uncommon winter visitant, which has been taken as 

 late as April 8. Alfred W. Anthony reports that he found it chiefly 

 in the pine woods above 3000 feet." 



Wetmore (1943) writes that Lincoln's sparrows are common winter 

 residents in southern Veracruz, Mexico. He collected a small series 

 in grassy clearings near the village of Tres Zapotes Mar. 8, 18, and 

 30 and Apr. 3 and 13, 1939, and on Jan. 23, 1940; also by the riverside 

 at Titacotalpam on Feb. 5, 1940, and in grassy pastures on old dunes 

 at El Conejo on Feb. 12, 1940. About the migration through Vera-
