The vulture - Rather, the (black) kite Isaiah 34:15 : "the kite," rather the red kite, remarkable for its piercing sight Job 28:7.

The vulture - דאה daah, from the root to fly, and therefore more probably the kite or glede, from its remarkable property of gliding or sailing with expanded wings through the air. The דאה daah is a different bird from the דיה daiyah, which signifies the vulture. See Bochart, vol. iii., col. 195.
The kite - איה aiyah, thought by some to be the vulture, by others the merlin. Parkhurst thinks it has its name from the root אוה avah, to covet, because of its rapaciousness; some contend that the kite is meant. That it is a species of the hawk, most learned men allow. See Bochart, vol. iii., col..

And the vulture, and the kite after his kind. Perhaps it might be better if the version was inverted, and the words be read, "and the kite, and the vulture, after his kind"; and the last word is by us rendered the vulture in Job 28:7 and very rightly, since the kite is not remarkable for its sight, any other than all rapacious creatures are, whereas the vulture is to a proverb; and besides, of the vulture there are two sorts, as Aristotle says (k), the one lesser and whiter, the other larger and more of an ash colour; and there are some that are of the eagle kind (l), whereas there is but one sort of kites; though Ainsworth makes mention of two, the greater of a ruddy colour, common in England, and the lesser of a blacker colour, known in Germany, but produces no authority for it; however, these are both ravenous creatures: of the kite, Aelianus says (m), it is very rapacious, and will take meat out of the meat market, but not touch any sacrificed to Jupiter; the truth of which may well be questioned; and of vultures he reports (n), that they will watch a dying man, and follow armies going to battle, expecting prey; See Gill on Matthew 24:28.

the vulture--The word so rendered in our version means more probably "the kite" or "glede" and describes a varying but majestic flight, exactly that of the kite, which now darts forward with the rapidity of an arrow, now rests motionless on its expanded wings in the air. It feeds on small birds, insects, and fish.
the kite--the vulture. In Egypt and perhaps in the adjoining countries also, the kite and vulture are often seen together flying in company, or busily pursuing their foul but important office of devouring the carrion and relics of putrefying flesh, which might otherwise pollute the atmosphere.
after his kind--that is, the prohibition against eating it extended to the whole species.
