L. plumbeiceps belongs to another group of the genus Leptoptila, with rufous lining 
to the quills as in L. verreauai, but with a nearly uniform crown of leaden grey. 
As with other species of the genus, considerable differences in the shades of the 
plumage are observable, and some specimens from Teapa and the Valley of Mexico 
are paler than birds from Guatemala and British Honduras, from which, however, one 
of the Atoyac examples cannot be separated. The females and young birds have a 
darker and browner vinaceous tint on the sides of the face and on the breast. 
Nothing has been recorded respecting the habits and nidification of L. plumbeiceps, 
but they are doubtless similar to those of other members of the genus.
