“ Acteon would stop in mid chase, Maria would defér her evening song, 
and Orpheus himself would drop his lute to listen to him, so sweet, so novel 
and romantic is the toll of the pretty snow-white campanero. He is never 
seen to feed with the other cotingas, nor is it known in what part of Guiana

“J have heard this drumming as early as February, and as late as

“This produces a hollow drumming noise that may be heard to a con-

gradually increases in velocity, and terminates with a rolling beat very
