HELMESTTHOPHAGA. 117 



Colorado valley i", Texas ^ ^. — Mexico ®, Orizaba {Botteri ^, Sumichrast ''), La Parada 

 (Boucard ^ ^), Oaxaca and Cinco Senores (Boucard ^) ; Guatemala, CHmuy, Vera 

 Paz (Sarg). 



This species has come under the notice of most of the collectors in Southern Mexico, 

 where it appears to pass the winter months. It is found in the mountaiaous parts of 

 the country, being apparently absent from the low-lying lands adjacent to the two 

 oceans. In Guatemala it never came under our own notice ; but a short time ago we 

 obtained a skin from Herr Schneider, of Basle, to whom it had been sent by Mr. Sarg 

 from Chimuy, a place in the vicinity of Cohan, Vera Paz. This proves that the bird 

 sometimes wanders thus far in its winter migration. 



Beyond our frontier it has been noticed during the colder months in Texas ^ ^- 

 Thence it spreads throughout the States and northwards to the Yukon river and the 

 Great Slave Lake. In the eastern States it is rare and of uncertain occurrence, but 

 yet has been met with in various places from Florida to Massachusetts ^'^. 



H. celata breeds in the Arctic regions and in the higher mountains of Colorado, 

 building on the ground a nest composed outwardly of fibrous bark and inwardly of 

 grasses and moss and sometimes with a lining of some kind of fur '^^. 



The species seems subject to some variation ia the colour of its plumage. This in 

 the countries bordering the Pacific takes a more decided character ; hence these birds 

 have been separated as a race and called H. celata, var. lutescens *.
