 but a slight elevation above the Pacific Ocean. In Guatemala it only twice came under 

 our observation — once when we found it flying over the open land near Dueiias, at an 

 elevation of nearly 5000 feet above the sea, and again near Godines, above the mountain- 

 lake of Atitlau, as high as 7000 feet. On both occasions the birds were flying low, 

 hawking for insects after the manner of their kindred."
