The Red-throated Humming-bird is abundant in the woods along the 

 Plata river, and ranges, I believe, fifty or sixty miles south of Buenos 

 Ayres city. Outside of the littoral woods it is very rarely met with. 

 The only nest I have found was in my own garden, and was placed on a 

 horizontal branch. The female continued sitting on the nest, which 

 contained two eggs, even when I placed my hand almost touching it ; 

 the male bird in the mean time exhibiting the greatest anxiety, and 

 hovering so near as almost to brush my face with its wings.

The Glittering Humming-bird appears in the vicinity of Buenos 

 Ayres in September, and later in the spring is found everywhere on the 

 pampas where there are plantations, but it is never seen on the treeless 

 plains. Its sudden appearance in considerable numbers in plantations 

 on the pampas, where there are flowers to which it is partial, like those 

 of the acacia-tree, and its just as sudden departure when the flowers 

 have fallen, -have led me to conclude that its migration extends much
