THE MANGROVE CUCKOO. 
is much like that of the other species described by me, perhaps only more 
rapid and elevated when they are proceeding to some distant place.

Adult Male. 
Bill as long as the head, broad at the base, compressed, slightly arched, 
acute ; upper mandible carinated above, its margins acute and entire ; lower 
mandible carinated beneath, acute. Nostrils basal, lateral, linear-elliptical,

scutella, which extend around it and meet behind ; toes two before, separated ;

claws slender, compressed, arched. 
Plumage soft, blended, slightly glossed. Wings long, the first quill short, 
the third and fourth longest and equal ; primaries tapering, secondaries broad

The general colour of the upper parts, including the wing-coverts and two 
middle tail-feathers, is light greenish-brown, the head tinged with grey; 
primary quills umber-brown ; tail feathers, excepting the two middle ones, 
brownish-black, tipped with white, the outer more largely. The lower

The female resembles the male, but is somewhat paler, especially on the 
lower surface, which is tinged with grey. 
The Seven Years Apple, Catesby , plate 59. 
The plant, on a twig of which I have represented the Mangrove Cuckoo, 
is found on all the Florida Keys, and at times is seen growing in large 
patches on the mud flats that exist between the outer islets and the mainland. 
The leaves are thick, glossy above, furred, and of a dull brown colour 
beneath.
