TTEANNUS. 101 



In Guatemala it has only been found on the slopes of the cordillera, between the 

 volcanos of Agua and Fuego. Here the late Mr. Frank Gates, who a few years 

 afterwards lost his life in South Africa, discovered it near Duenas, where we subse- 

 quently met with it. The white margin to the outer tail-feathers shows rather 

 conspicuously when the bird is flying, rendering it distinguishable from the common 

 T. melanchoUcus. 



In California the species is stated to be migratory, arriving towards the end of 

 March, and leaving again in October. Where these birds pass the winter months has 

 yet to be determined. 



The nest is described as built on a low branch, and constructed of lichens, twigs, 

 coarse grass and wool, and lined with hair. The eggs are creamy white, spotted with 

 purple of two shades near the larger end ^. / 



b'. Cauda furcata.
