It looks similar to a vulture. When a monster is killed and left alone it will fly down to eat it. It lives in groups of 3-5 birds. How many of them come down depends of the size of the killed monster (for example a small Minion will lure only 1 or 2 but a small boss monster can lure 3 or 4). It has no element or ailment but its very persistent when attacked and endure many attacks. The weakness is dragon, then water.
I've thought of a quest where you must kill monsters to kill a certain number of Vorcaros.
It lives in almost every area but the volcano areas, the Lava Landscape, the Tundra and the Antarctic Ground.
