Parus hudsonicus . 



Concord, Ivlass. 



1896. After dining at the calDln Will Bartlett and I walked out 



Oct. 31. over the old cart-path to Birch Island. We were standing by 

 the boat landing there looking for Grebes when suddenly the 

 emphatic chip , chu-dee . dee of a Hudson's Bay Titraouse rang 

 out on the still air directly behind us, and was immediately 

 repeated. Turning and looking upward we saw the bird swaying 

 on the topmost twig of a birch within twenty yards or less. 

 It was quite alone and, indeed, there were no other birds of 

 any kind at the time on this small and scantily-wooded meadow 

 island. Probably it had only just come across the meadows 

 and had alighted merely to rest for a moment for I had only 

 just time to tell Bartlett what it was when it started again 

 and made off over the river heading at first for the Bedford 

 shore but finally turning to the right and disappearing among 

 the pines on Davis's Hill. We followed it to where we had seen 

 a mixed fl^P^ a short time before but it had not joined them. 

 I fancy that he kept straight on through or past them as, indeed 

 he must have done through or near many a similar flock since 

 leaving his hpme in the North. His course during the short 

 time we had hiin in sight was due south and he was probably 

 actually migrating at the time.
