Translation of manuscript note on accompanying leaf: Falco nigricans [The black falcon]
F., with a dark cere, yellow feet, and black body
with tawny reddish-brown spots crossing it.
It is the size of the Gallinae meleagridis [the Guinea-Fowl]. The head is small, black, with very small reddish-brown
spots. The beak is small, and lead-coloured:
the cere is dark. The top of the neck and the back
are a pure black; the breast and abdomen
are black and sprinkled with irregular reddish-brown
spots. The tops of the wings are black with spots
crossing them, the primary feathers (of which there are
eleven) are lead-coloured, the secondary feathers (of which there are ten)
are tawny; the undersides of the wings are paler. The tail is the same but longer than the wings:
There are twelve flight feathers on the sides of the tail that are tawny with pale spots; the flight feathers in the middle of the tail are white, all those behind the middle
are black, and have white tips. The thighs are black
with an abundance of pale reddish-brown bands. The tibias are bare, and yellow.
It lives in the Grenadine Islands.
