character that it is nearly as startling as the report of 
a gun. I have never heard any bird note which at near 
range sounded anything like so loud, yet it apparently 
does not carry so well as the croak of the Toucan, which 
can be heard fully as far away although it is not a very 
loud call when one is directly under the tree on which the 
Toucan is sitting. 
As I stood beneath the Bell Bird this afternoon, 
his bok at first made me actually jump each time it was 
delivered. It also produced a fluttering vibration of my 
ear drums which was diaagreeable and somewhat painful. 
At each utterance of this note, the bird opens his 
bill to its widest extent and throws his head forward and 
down with a violent, convulsive jerk as if he were in a 
passion and striking viciously at some rival. This jerk 
is indeed so violent that the bird evidently has some 
slight difficulty in maintaining his footing during its 
delivery, as well as in afterwards recovering his normal 
balance or pose. 
The second note, tue , is much softer and less loud 
than the bok and is delivered from six to eleven times 
in such rapid succession that the notes are run together 
in an unbroken series. Despite this fact each tue is 
followed by a metallic ring which sounds exactly like an 
echo and appears to be of nearly the same duration as the
