A common species in the Temperate Zone of the Eastern Andes; numer- 

 ous on the Savanna of Bogota. None was secured in the Central Andes 

 but Miller and Boyle collected two on the Paramillo in the Western Andes, 

 the most northern record for the species. Our specimens agree with others 

 from Ecuador, but the two Paramillo birds have somewhat larger bills than 

 the others.
