ground. Curious to find out the cause of their excitement I quietly 

 watched them for about five minutes, when to my astonishment a small 

 poisonous snake fell to the ground out of the hole at which they were 

 pecking.

One of the rarest of the Costa Rican Dendrocolaptidce, of which 



there are not more than a half-dozen skins in existence, of which 



I can find any record. Three out of the five skins in the United 



States came from Juan Vinas, and the other two at no great distance 



from that point. The bird is probably found only in the mountains 



or rather in the plateau district, and only on the Caribbean slope. 



Nothing is known of its habits, more than that it is an inhabitant of 



the forest, and feeds after the manner of all true Dendrocolaptine birds.
