 article could have been found by us, as any one would have taken it to be sea-water which flows and ebbs to 

 it, had we not seen our little friend in the act of drinking. No other water was discovered, although it 

 doubtless exists in other places on the Island."

"Not an abundant species, although not an uncommon one in this locality. Inhabits chiefly the woods; 

 resident all the year. I found it also in Tcpic and San Bias regions."

" An abundant and common species and a constant resident ; it is well distributed throughout the woods 

 of the tierra caliente. They associate in flocks of from ten to thirty. Their long pensile nests are sometimes 

 three or four feet in length. I found it equally abundant in Tehuantepcc, but none in the Tres Marias 

 Islands. 



"It does not migrate except from one part of the forest to another. The Long-tailed Jay {Colacitta 

 collwi) fi-equently accompanies them in their perambulations through the woods in quest of their insect prey, 

 or various kinds of fruit upon which they subsist. 



"Among the many curious objects which meet the eye of the traveller in the tropical regions of Western 

 Mexico, are the long pendant nests he sees swaying in the breeze, attached to a small twig and frequently 

 overhanging the path he is travelling. These are the nests of the Double-crested Oriole. Beneath the wide- 

 spreading branches of the mimosa, acacia, higucro, or any large tree that affords an ample shade, may often
