The Ospreys have the beak and feet of the Fisher Eagles; but their 
claws are round underneath, while in other birds of prey they are 
grooved or channelled; their tarsi are reticulated, and the second 
quill of their wings is the longest. 
Only one species is known, which is found along the shores of 
fresh waters in almost every part of the globe, varying but little in 
plumage: itis the 
Falco halixtus, L.; Enl. 414, and better, Catesby, II; Wils. 
V, xxxviis Vieillot, Gal. ii; Naum. 16. (The Osprey.) A third 
smaller than the Ossifragus; white, with a brown mantle; a 
brown band descending from the angle of the beak towards the 
back; brown spots on the head and neck, also «a few on the 
breast; the cera and feet, sometimes yellow, and sometimes blue. 
The species of the genus 
Circartus, Vieillot, 
Are in a manner intermediate between the Fisher-Eagles, the Os- 
preys and the Buzzards. ‘They have the wings of the Eagle and 
Buzzard, and the reticulated tarsi of the Osprey. : 
F. gallicus, Gm.; F. leucopsis, Bechst.; F. brachydactylus, 
Tem.; Enl. 413; Naum. 153 Jean le Blane. Superior in size ta 
the Osprey; the curvature of its beak is more sudden than in 
the other Eagles, and the toes are shorter in proportion. It is 
brown above, white beneath, with pale brown spots; three light 
bands on the tail. Its carriage is rather that of a Buzzard than 
of an Eagle, and it feeds chiefly on Frogs and Serpents. ‘ 
F. ecaudatus, Sh.; Le Bateleur, Vaill. Afric. 7 and 8. An 
African species, remarkable for the extreme shortness of its 
tail, and its beautifully variegated plumage. The cera of its 
beak is red.(1) 
America produces Eagles with long wings, like the preceding 
ones, and naked scutellated tarsi, in which a more or less considera- 
ble portion of the sides of the head, and sometimes of the throat, is 
Aigle aguia, (F. aguia, T.) Col. 302;—the F. ichtyxtus, Horsf. Jay.;—the Milva- 
£0 ochrocephalus, Sp. 1, or Chimachima, Azz. or F. degener, lig. We should also 
remember that the transition from the Eagles to the Buzzards is effected by insen- 
sible gradations.
