FAMILY PANDIONIDAE. 
The family contains only one species, the Osprey, peculiar by its having 
the outer toe reversible, and no aftershaft to the feathers. The tarsus is naked 
(except at the top anteriorly) and covered with very rugose small scales. The 
claws very long, and curved almost to a semicircle; the toes furnished below 
with pads covered with small, strong, sharp points or spines, adapted for holding 
the fish upon which it preys. Size large medium; wing very long, extending 
beyond the tip of the tail. Migratory and stationary. Eggs 2 — 3. Almost cosmo- 
politan in range, but varies locally to some extent.

+ 29. PANDION HALIAETUS (L.). 
Osprey. 
The genus Pandion contains only one species, P. haliaetus^ which is almost 
cosmopolitan in its range. In the Old World, in America, and in Australia some 
difi’erences of size and coloration have arisen, which makes it advisable to adopt 
the three subspecies already distinguished.
