Then there are several of the allied species, of which the best example is perhaps the Short-toed Eagle (_Circaëtus cinereus_), a bird which is extremely plentiful in the Holy Land--so plentiful indeed that, as Mr. Tristram remarks, there are probably twice as many of the Short-toed Eagles in Palestine as of all the other species put together. The genus to which this bird belongs does not take rank with the true Eagles, but is supposed by systematic naturalists to hold an intermediate place between the true Eagles and the ospreys. The Short-toed Eagle is seldom a carrion-eater, preferring to kill its prey for itself. It feeds mostly on serpents and other reptiles, and is especially fond of frogs. It is a large and somewhat heavily built bird, lightness and swiftness being far less necessary than strength in taking the animals on which it feeds. It is rather more than two feet in length, and is a decidedly handsome bird, the back being dark brown, and the under parts white, covered with crescent-shaped black spots.

The Osprey, or Fishing Eagle--Its geographical range--Mode of securing prey--Structure of its feet--Its power of balancing itself in the air. We now come to the Osprey itself (_Pandion haliaëtus_), which was undoubtedly one of the birds grouped together under the collective term Asniyeh. This word occurs only in the two passages in Deut. xiv. and Lev. xi. which have been several times quoted already, and need not be mentioned again. This fine bird is spread over a very large range of country, and is found in the New World as well as the Old. In consequence of its peculiar habits, it is often called the Fishing Eagle. The Osprey is essentially a fish-eater. It seems very strange that a predacious bird allied to the eagles, none of which birds can swim, much less dive, should obtain its living from the water. That the cormorant and other diving birds should do so is no matter of surprise, inasmuch as they are able to pursue the fish in their own element, and catch them by superior speed. But any bird which cannot dive, and which yet lives on fish, is forced to content itself with those fish that come to the surface of the water, a mode of obtaining a livelihood which does not appear to have much chance of success. Yet the Osprey does on a large scale what the kingfisher does on a small one, and contrives to find abundant food in the water.
