140 THE MYRTLE WARBLER. 



spot on the edge of the wing is not very conspicttous in the female, but once 

 found it settles all dispute, however much imagination may rebel. 



The Black-throated Blue Warbler is rather deliberate in movement, quiet 

 and genteel. It is not very difficult to approach it, and a pruHent observer 

 may sometimes attain inspection at arm's length. In such cases,' however, 

 it is the bird that makes the advances. The surest opportunity comes when 

 the bird has been seen in a front yard evergreen. Then the observer may 

 approach quietly, while the bird, trusting to the density of the foliage, pursues 

 intently his entomological researches, or even publishes his prosy song. Dzwee, 

 dzwee, dzweedt comes in a matter of fact voice, or with a curious upward turn, 

 from the depths of the foliage. The sounds are consonantal, hard, and deep, 

 but not out of keeping with the bird's demure ways. On rarer occasions a 

 sprightly and much more musical ditty is heard, Chew, we-o, we-o, we-o, 

 ive-o, zvich, i-wich, i-wich. 



This Warbler is common in spring but is even more noticeable in autumn, 

 since it is one of the few species which do not don plainer garments. Its fall 

 movement is leisurely and it finds a congenial companion in the dropping leaf.
