Anthus rubescens (Tunstall). Pipit 



A large flock that was seen near Hazelton on May 26 was the last 

 migrating band to pass through. The species was next encountered 

 on the summit of Nine-mile Mountain, where it was breeding in small 

 numbers. A special effort was made there to get birds in the juvenal 

 plumage, but the j^oung were extremely wary, in striking contrast to 

 the tameness of their parents, and onlj one was collected. Pipits 

 reappeared in the lowlands, in Kispiox Valley, on September 2. and 

 were seen in fair abundance there and at Hazelton until September 20. 



In Kispiox Valley, September 4, two pipits Avere collected, the two 

 together and not otherwise accompanied. One was still mostly in 

 juvenal plumage. The other, in fully acquired winter plumage, I 

 assumed to be an attending parent, but on dissection it proved to be 

 an immature bird. The occurrence is of interest, first, as indicating 

 that a young bird still in juvenal plumage can start to migrate and 

 travel a considerable distance, for the juvenal mentioned must have 

 come a long way from where it was hatched, if only from the nearest 

 mountain top ; and secondly, as demonstrating the early age at which 

 a young bird can care for itself, independent of its parents. 



Pipits in late March and early April undergo an extensive molt 

 whereby the breeding plumage is acquired. In this plumage the upper 

 parts are grayish, compared with the brown winter plumage, and the 

 lower parts cinnamon buff. The female, as compared with the male, 

 is less gray (more brownish), above, and more heavily spotted below. 

 The cinnamon is evanescent, and by the end of July has almost all 

 faded away. Then, by the f^U molt, in late August and early Sep- 

 tember, the winter plumage is acquired, differing from the breeding 

 garb in being brown above and more heavily streaked below, but, in 

 both old and young, distinctly cinnamon tinged ventraUy. Again the 

 cinnamon fades out and by the end of November the birds are dull 

 brown above, and whitish, streaked with dusky below, as we usually 

 see them in their winter home. 



Thirteen specimens collected (nos. 42547-42559). 



Dumetella carolinensis (Linnaeus). Catbird 



On June 10 a catbird was shot within a stone 's throw of the rail- 

 road station at Hazelton. This bird (no. 42560) was an adult male 

 and in breeding condition, but his mate was not seen,. nor was any 

 other of the species encountered during the summer. This, I believe, 

 is a material extension northwestward of the range of this species.
