also as regards to the rosy spot on the throat, .etc." Further on, in siteaking- of 

 the'habits of //. afjla'ue, they sa)-: "In all parts of our region tlu^ i-iuigc in alti- 

 tude of this species is very considerable, and extends from the sea le\'el to an 

 altitude of at least 8,000 feet. In the Tres Marias Grayson found it only in 

 thick woods, where it was seen searching for insects, sometimes, darting after 

 them when on the wing, at other times looking for them among the lenves and 

 branches, not unlike the Warblers. Its notes are feeble and but seldom uttered, 

 and its habits are solitary. This island bird has been separated by Mr. Ridgway 

 as PJati/jJsaris iiisular'is. 



"Mr. Robert Owen found a nest of this bird on May 15, 1860, atChuacusin, 

 Guatemala, and sent ns the female, its nest, and two eggs. The nest Avas entirely 

 composed of tendrils, strips of bark, and grass, so as to form a hanging nest, 

 open at the top and about 2 inches deep. It was bixilt between and hung from 

 the forked branch of a sapling at the foot of a mountain. The egg is white, 

 beautifully marked with pencilings of pinkish red and scattered spots of the 

 same color; these markings are much blended and concentrated at the larger 

 end."i 



There is nothing recorded as }'et regarding the nesting habits and eggs of 

 Xantus's Becard; but they are not likely to differ very nmch from the nest and 

 eggs oi Hadrostomus aglaice, to which it is closely allied. As far as I can learn 

 the eggs still remain unknown.

The Fork-tailed Flycatcher can only be considered an accidental straggler 

 within our borders. It is a common bird throughout the more le^el and open 

 portions of Central America, and also throughout the greater part of South 

 America. 



The Scissor-tail Tyrant, or "Tijereta," as this species is called by Sclater and 

 Hudson, "is migratory, and arrives, already mated, at Buenos Ayres at the end 

 of September, and takes its departure at the end of February in families, old 

 and young birds together. In disposition and general habits it resembles the
