run backwards and forwards; and so great is her anxiety, that 
she will venture within two or three yards of him. 
In another respect the present species agrees with T. umbellus, 
in perching on stumps of decayed trees in the darkest part of the 
forests, drumming, which is effected in the same way, namely, by 
giving two or three loud distinct claps with the wings, then others 
gradually quicker and quicker, until the sound dies in the di- 
stance,—not unlike the sound of very distant thunder. The voice 
is a continuation of measured sounds, not unlike the ticking of a 
large clock, Tuck, tuck, tuck, slowly pronounced, and, when the 
bird is on the wing, is a sort of chuckling noise. This very fine 
bird is an inhabitant of the woody parts of the coast of North- 
. west America, between the parallels of 40° and 49? from Cape . 
Mendocina on the south, to the Straits of Juan ge Fuca, Quadra, 
and Vancouver's Island on the north. 
The name is a tribute to the merits of my friend Joseph Sabina, 
Esq., whose intimate acquaintance with this widely-dispersed 
and highly interesting genus, and whose distinguished services 
in natural history in general, are universally known and justly 
appreciated. :
