DENTIROSTRES.

Mr. Strange tried to find it on its nest^ but never suc- 
ceeded. He found a nest^ placed in the spur of a large fig- 
tree : this the natives assured him was the nest of the Colwin, 
their name for this Menura, The nest was large and domed"^. 
Mr. Strange has seen the Albert lyre-tail jump not less than 
ten feet from the ground^ to some convenient branchy so that 
the powerful femoral muscles which move the large feet are 
useful in more ways than one^ for these leaps are habitual to 
the bird; Mr. Strange observing that it continued to ascend 
in successive jumps^ till it had reached a height sufficient 
to fly from it into the gully below. 
The third great group into which the Passerine birds are 
divided is named Dentirostres, from the upper mandible 
being notched on each side toward the point. Mr. Blyth^ 
one of the best authorities on birds^ remarksf that ^^no 
trace of this notch is ever visible in the bone^ from which 
the tooth^^ of certain Accipitres is a true process. 
This group of birds contains the Warblers, Thrushes, Fly- 
catchers, Berry-eaters, and Shrikes, to the habits of some 
of the species of which families we now direct the reader^'s 
attention.
