130 MNIOTILTID^. 



The distribution of this species in winter in Central America is peculiar. It has been 

 found in the southern provinces of Mexico, Vera Cruz, Oaxaca, and Tehuantepec, and 

 immediately to the southward over a wide district of Guatemala, extending across the 

 country ; but beyond this we lose all trace of it until we come to the State of Panama, 

 where it occurs not unfrequently on the line of the Panama railway. This is its most 

 southern limit. In Cuba it is of rare occurrence, appearing sometimes in the month of 

 April on its passage northwards ^^. It also occurs in the Bahamas ^, but not in any 

 other of the West-India Islands. 



In summer it spreads over the Eastern States northwards to Labrador, Hudson's Bay, 

 Great Slave Lake, &c., and westwards to the Eocky Mountains of Colorado, breeding in 

 the New England States and northwards ^^. 



Its song is described as clear and sweetly modulated, surpassing in quality those of 

 most of the family. It frequents low woods, searching for its food amongst the 

 branches and running up and down the trunks of trees in pursuit of insects and their 

 larvse. It also catches insects on the wing, and takes them from open flowers ^^. The 

 nest is usually placed in a fir tree a few feet from the ground ; it is described as a rather 

 loose shallow structure, made almost entirely of slender grasses, fine stems of plants, 

 a little moss or spruce-twigs, and lined with fine black roots of herbaceous plants. The 

 eggs are cream-colour or ashy white, sparingly spotted with lilac and umber ^^.
