TANAGER. 33 



Inhabits St. Domingo, and there called the Organist, from its 

 note, forming a complete octave, one note successively after another ; 

 said not to be uncommon, but difficult to be obtained, for like the 

 Creeper, it continually shifts to the opposite part of the branch from 

 the spectator's eye, so as to elude his vigilance. 



Du Pratz, in his history of Louisiana, mentions a bird whose 

 notes are so varied and sweet, and warbles so tenderly, as to be 

 thought superior to a Nightingale. It is said to sing for near two 

 hours, scarcely taking breath, and after respite for about the same 

 time, begins again ; whether this is a different bird or not, from ours, 

 cannot be determined, as Du Pratz gives no description.
