western part of the Strait and Western Channels, as well as at Chiloe. 

 It is of a bold disposition, allowing one to approach within a short dis- 

 tance of it, and then making off with a heavy flapping flight, uttering at 

 the same time a very hoarse croak." (The italics are the author's.) 



It is probable that all of Dr. Cunningham's notes in the Natural History 

 of the Straits of Magellan refer to this species, which is so different from 

 its congener, and which always impressed him so. He must have seen one 

 individual at least in the Falkland Islands. As noted before, this is the 

 form that occurs in the extreme south of Patagonia, while N. tayazu-guira 

 does not range down as far as the Straits, though it occurs in the Falkland 

 Islands. The relationship and distribution of these herons presents an 

 attractive field for further investigation.
