the owl - It is generally supposed the ostrich is denoted by the original word.
the nighthawk - a very small bird, with which, from its nocturnal habits, many superstitious ideas were associated.
the cuckoo - Evidently some other bird is meant by the original term, from its being ranged among rapacious birds. Dr. Shaw thinks it is the safsaf; but that, being a graminivorous and gregarious bird, is equally objectionable. Others think that the sea mew, or some of the small sea fowl, is intended.
the hawk - The Hebrew word includes every variety of the falcon family - as the goshawk, the jerhawk, the sparrow hawk, etc. Several species of hawks are found in Western Asia and Egypt, where they find inexhaustible prey in the immense numbers of pigeons and turtledoves that abound in those quarters. The hawk was held pre-eminently sacred among the Egyptians; and this, besides its rapacious disposition and gross habits, might have been a strong reason for its prohibition as an article of food to the Israelites.
