 INHABITERS. 



Regulus calendula. The Ruby-crowned Wren. 



This pretty little wren is at once distinguished 

 by the crown, which has a concealed patch of 

 scarlet feathers, which are white at the base. 

 Its song is charming, and harmonious. Arrives 

 here about the middle of May, on its way north 

 to breed, and visits us again in September, while 

 migrating south. Feeds upon insects and their 

 larvae. 



Regulus satrapa. The Golden-crested Wren. 



This wren is distinguished from the Ruby- 

 crowned, by a crest of orange-red, encircled by 

 yellow. Visits Canada in the spring and autumn. 

 Breeds north of Ontario. Feeds upon insects. 



Regulns. cuvieri. Cuvier's Golden-crested Wren. 



This diminutive and beautiful bird differs from 

 the Regulus Satrapa in having two black bands 

 on the crown, separated by a white band. This 

 wren usually accompanies the two preceding 

 species, in their spring and fall migrations.
