Black-Winged Kite
There are several species of the kite which feed upon small birds, mice, reptiles, and fish. It was forbidden to the Israelites for food (Lev. 11:14; Deut. 14:13). The same Hebrew word is translated “vulture” in Job 28:7, “falcon” in the RV. It is only distinguished in scripture for its keenness of vision, but this characteristic would apply to many different birds. The common kite is the Milvus regalis.
