17. There are other records from farther north, but it seems probable 
that they belong to the Hermit Thrush. It was reported by Mr. Nash 
from Portage la Prairie, Manitoba, though it is very scarce in that 
region. The records are too indefinite to admit of tracing the move- 
ments of the bulk. The species breeds throughout its range in the 
district, and winters beyond our border. Dr. Agersborg states that 
it is a rare summer resident in southeastern Dakota, and Colonel Goss 
records it as abundant in eastern Kansas. 
In the fall of 1884, at Des Moines, Iowa, the last Wood Thrush was 
seen August 25. At Mount Carmel, Mo., the bulk left September 1, 
and the last was seen September 14. 
In the spring of 1885 the following complete records of the movements 
of the four species of Thrushes most commonly confounded were re- 
ceived, and may be of use as a table of reference. 
Mr. Widmann’s record at Saint Louis was as follows: 
Hermit Thrush. First, April 1; bulk present from April 6 to April 18; last, 
April 24, 
Olive-backed Thrush. First, April 17; bulk present from May 4 to May 6; 
last, May 20. 
Wilson’s Thrush. First, April 22; bulk present from May 5 to May 12; last, 
May 12. 
Wood Thrush. First, April 19; bulk came April 28; remains to breed. 
In the spring of 1884 the movements of these species at Saint Louis 
were as follows: 
Hermit Thrush. First, April 1; bulk present from April 14 to April 19; last, 
April 28. 
Olive-backed Thrush. First, April 26; bulk present from April 29 to May 12; 
last, May 26. 
Wilson's Thrush, First, April 29; never common; last, May 21. 
Wood Thrush. First, April 19; bulk came April 26. 
In the spring of 1883 the record was: 
Hermit Thrush. First not noted; bulk present April 10 to April 12; last, 
April 13. 
Olive-backed Thrush. First, April 26; bulk present from May 2 to May 18; 
last, May 24. 
Wilson’s Thrush. First not noted; bulk present from May 15 to May 17°. 
last, May 21. 
At Jefferson, Wis., in the spring of 1883, I made the following rec- 
ord: 
Hermit Thrush. First, April 4; bulk present from April 20 to May 6; last, 
May 10. 
Olive-backed Thrush. Second seen May 3; bulk present from May 12 to May 
24; last, May 31. 
Wilson's Thrush, First, May 7; bulk present from May 12 to May 24; last, 
May 30. 
Wood Thrush. First, May 10; bulk came May 17. 
These are the only complete records received. From them it will! be 
seen that although the exact dates are somewhat variable, the relative
