T. ustulatus are also made by Mr. Chapman (Bull. 
References to the likeness of certain specimens to 
Amer. Mus. iii. p. 154) and by Mr. Ridgway himself 
Turdus fuscescens is more eastern in its range than the 
their breeding-range the two forms inhabit dist in close proxi 
they also follow the same lines of migration, as they occur together in their winter-quarters. 
Mr. F. M. Chapman, in his paper on the Birds of British Columbia, makes the following remarks 
on the plumage of Turdus salicicola :—* А specimen in 
fall-plumage from Ducks is darker than spring 
birds from Ashcroft, and is remarkably close to spring specimens of Turdus ustulatus from the coast. 
A young male in spotted plumage taken from the same locality, August 8, is very different from 
Turdus fuscescens of nearly the same age. 'The light centres to the feathers of the upper parts are 
buffy, not tawny, while the wings and tail are russet-olive, not tawny brown. The differences are 
thus similar to those shown by the adults of both forms, but are more pronounced." 
Mr. Ridgway, in his original description of the Willow-Thrush (Proc. U.S. Nat. Mus. iv. p. 874), 
records a specimen from the Souris River, in Dakota, this being the bird identified by Prof. Elliott 
Coues as Turdus swainsoni (Bull. U.S. Geol. Surv. iv. no. 3, p. 550). (Cf. Thompson, Proc. U.S. Nat. 
Mus. xiii. p. 633.) Mr. Ridgway likewise refers a specimen from Fort Rice, Dakota, to T. salicicola, 
and the single specimen in the British Museum procured during the survey of the 49th parallel is 
undoubtedly of the same race. I observe, however, that Mr. Ridgway refers a Pembina skin obtained 
by Dr. Coues on the same Survey to the true T. fuscescens. | | 
А specimen from Montana is in the United States Museum (Ridgway, l. с.), and Mr. Williams 
says that the bird arrives ai Grant Falls about the 15th of May and nests in the mountains as 
high as 4200 feet. “It is the commonest and most widely distributed of the Thrushes in Montana 
(Auk, vii. p. 292). ۰ 
From Wyoming specimens have been examined by Mr. Ridgway from Laramie and Fort Bridger, 
the latter having been obtained at the end of May (Ridgway, J. c.). 
Mr. F. M. Chapman, in his paper on the collections made by Mr. Clark P. Streator in British 
Columbia, writes as follows :—“ Captain Bendire informs me that the previously most northern 
discovery of the nest of this species is at Sassin, near Spokane Falls, from which he has recently 
received a nest and four eggs, taken on the 7th of June, 1890, with the female, a capture which he 
permits me to record. Mr. Streator's observations further extend this bird's range, and show it to be 
a common summer resident at least as far north as Ducks and Ashcroft.” 
Several specimens from Fort Garland, in Colorado, are recorded by Mr. Ridgway (1: c.), and the 
Henshaw Collection contains examples from the same place and from Colorado Springs killed in May 
and June. It was also found breeding near Denver (Hensh. Zool. Wheeler's Exped. 1875, p. 148). 
Mr. Drew gives the vertical breeding-range in Colorado as extending from 5000 to 8000 feet (Auk, 
ii. p. 15). Mr. Ridgway also found this Thrush nesting in the valleys of the Bear, Provo, and Weber 
Rivers in Utah (Orn. 40th Parallel, p. 398). 
From Arizona Mr. Scott records a specimen obtained by Mr. Herbert Brown near Tuczon in 
Мау (Auk, v. p. 169). 
In other parts of the United States the Willow-Thrush appears to be a migrant. In Illinois it 
was first observed by Mr. H. K. Coale at Chicago (Bull. Nutt. Orn. Club, p. 239, 1883), and he 
obtained a second specimen in May at Ravenia, in Lake County (Auk, xi. p. 222). Mr. Gault has 
not only procured examples at Glen Illyn in May, but believes it to be a regular autumn migrant in 
the State (Auk, хіі. p. 85). I am inclined to consider а specimen in the Henshaw Collection, from 
Lowville, New York, shot by Mr. A. J. Dayan on July 3rd, 1876, as belonging to 7. salicicola, as 
well as a male bird procured by Mr. Henshaw himself at Cambridge, Mass., on the 12th of June. 
СМІ. Loomis has obtained it in Chester Co., South Carolina, in October (Auk, vi p. 194), and 
(Proc. U.S. Nat. Mus. iv. p. 375).
