movements of the first three species remain the same for the three 
years and in the two widely separated localities, while the Wood Tirnsh 
shows great constancy in the time of its arrival at Saint Louis, without 
regard to the weather. 
The records of the migration of the Wood Thrush in the spring of 
1885 fell between April 19, at Saint Louis, Mo., and May 18, at Lanes- 
boro, Minn. 
Tn the fall of 1885, at Grinnell, Iowa, the last was seen September 16, 
and at Saint Louis, Mo., September 26. 
756. Turdus fuscescens Steph. [2.] Wilson's Thrush. 
This is rather a retired bird and one not often noticed in its late and 
hurried migration. It winters principally south of the United States, 
though a few stay in the Gulf States and Florida; hence it has a long 
journey to perform before reaching its breeding grounds in the nortb- 
ern United States and British America. In the spring of 1884 few 
records were made of its movements, and none whatever of its first ap- 
pearance along our southern border. No uotes were contributed from 
any locality south of Saint Louis, Mo., where two birds arrived April 
29. Four birds, the highest number seen in one day, were recorded May 
17, and May 21 the last one left, but managed to sing a little before its 
departure. A little farther up the river, at Burlington, Iowa, the first 
was noticed May 5, though one had been seen at Chicago, IIl., two 
days previcusly. May 11 and May 12 it reached West De Pere, Wis., 
and Lanesboro, Minn. A week later (May 18) it reached Oak Point, 
Manitoba. It breeds abundantly in Manitoba and occasionally in the 
Northern States, sometimes as far south as northern Illinois and Iowa. 
Mr. Kline took two sets of eggs at Polo, IIL, during the season of 1883; 
Dr. Agersborg has found it breeding at Vermillion, in southeastern 
Dakota, and its nest and eggs have been taken at Grinnell, Iowa. 
In the spring of 1885 the notes on Wilson’s Thrush were more regu- 
lar than those on the other species of Wood Thrushes. At Saint Louis, 
Mo., and Paris, Il., the first were reported April 22. From May 5 to 
May 9 they were noted at Mount Carmel, Mo., Iowa City, Iowa, Grin- 
nell, Iowa, Lanesboro and Lake City, Miun., and Durand, Wis. May 13 
they appeared at River Falls, Wis., and May 16 I saw a single bird 
near White Earth, Minn. 
756a. Turdus fuscescens salicicolus (Ridgw.). [—]. Willow Thrush. 
This western form of Wilson’s Thrush was described by Mr. Ridgway 
from the Rocky Mountain region of the United States. It was taken 
by Coues on the Souris River, along our northern boundary, and an 
accidental straggler came to Chicago, Ill., where it was taken Septem- 
ver 16, 1877, by Mr. H. K. Coale. The specimen was identified by Mr. 
Ridgway. Recently it has been killed in Cook County, Tex., by Mr. 
Ragsdale. Specimens were taken at Devil’s Lake and Pembina, Dak., 
by Mr. Vernon Bailey, in the summer of 1887,
