 (L. Fraser) ; Costa Eica {Zeledon ^^). 



Sumichrast states ^ that this species is common in the hot and temperate regions of 

 the State of Vera Cruz, and is also found on the plateau ; but, so far as our experience 

 goes, it is the only species of the highlands, and is far more abundant on the western 

 side of Mexico than elsewhere. Xantus found it breeding on the Volcano of Colima, 

 but at what elevation is not stated. 



Nortbwards it spreads throughout the "Western Sierra Madre, and thence across the 

 United States frontier to the Eocky Mountains, as far north as Wyoming. But in the 

 north it is only a summer visitor, retiring southwards after the breeding-season, at the 

 approach of winter. In Guatemala it is perhaps more abundant than would appear 

 at first sight, as its resemblance to T. melancholicus is close enough to render it easily 

 mistaken for that bird. 



Many years ago Skinner gave us a specimen said to have been shot near Salama in 

 Vera Paz, and during his short stay in Guatemala Fraser obtained one near Duenas. 

 These are the only authentic specimens from that country we have seen. 



Its occurrence in Costa Eica rests on a statement to that effect in the ' History of 

 2^orth- American Birds,' and its mention in Zeledon's ' Catalogue of Costa Eican Birds.' 

 We have no record to add of its occurrence so far south. 



The nest obtained by Xantus is described by Brewer as a slight structure composed 

 'of wiry grass mixed with bits of wool and lined with finer grasses. The eggs are pure 

 ■white, freckled on the larger end with purplish brown and greyish lilac. ^

Though a well-known bird in Western North America, T. verticalis appears to be 

 seldom found in Mexico, and at present the only records we have of its occurrence in 

 that country are those of Grayson and Xantus mentioned above at Tepic and Colima ^.
