570 THE BIRDS OF MAINE 



lavender-gray, forming a slight wreath about the larger end. 

 They measure 0.60 x 0.48, 0.58 x 0.47, 0.60 x 0.48, 0.59 x 

 0.49, 0.59 X 0.48. The eggs were perfectly fresh. 



Wilson's Black-cap is often seen in company with the 

 Canadian Warbler during the migrating season. Their man- 

 ner of feeding somewhat resembles that of the Canadian species. 



They feed in briery thickets, picking up insects very nimbly. 

 They have the talents of a Flycatcher, and capture much of 

 their food on the wing, but do not like the Flycatcher return 

 to the same perch. It utters a pleasing song occasionally as it 

 gleans for food, which I am unable to describe or liken to any 

 other Warbler. 



Nuttall describes it, "tsh-tsh-tsh-tshea," while Goss writes it 

 "zee-zee-zee-zee-e" : the latter would be my idea of it with a 

 rising inflection on the last e. Several people have mentioned 

 seeing this Warbler with young, but I am unable to learn of 

 any others who have seen the nest. I believe as stated previous 

 it is a more common nester throughout the Canadian Fauna, 

 in this State than is commonly supposed, as there are many 

 places in the northern part of the State, where I would con- 

 fidently look for this species to be nesting." 



686. Wilsonia canadensis (Linn.). Canadian Warbler; 

 Canada Flycatching Warbler. 



Plumage of adult male : above cinerous gray, the crown spotted with 

 black or toward and on forehead black, narrowly edged with grayish ; auric- 

 ulars and sides of neck black ; yellow line from bill to eye and yellow eye 

 ring ; a series of black spots like a necklace across the breast ; throat, lower 

 breast and belly yellow. Plumage of adult female : very similar to that of 

 male but nearly always readily distinguishable ; the black spots on forehead 

 are lacking, the lores less distinctly black, the necklace less distinctly black 

 and more limited. Immatiure plumage : quite similar to that of adult female, 

 but the necklace is an obscure series of duller or more grayish spots. Wing 

 2.57 ; tail 2.28. Bill with bristles at base.
