Deer

The Deer is the symbolic herd-huntable creature in Age of Empires II, Age of Empires III and Age of Mythology games.

Age of Empires II
The deer  had 140 meat and ran away when hunted, but hunters could now haul meat away in much larger lumps (35 meat/trip).

Age of Empires III
The Deer has reached its final iteration, and now has 20 hp (2 shots/1 with Blunderbuss, thanks to Villager attack bonuses), and due to improved meat storage methods has had its meat content boosted up to 400 meat, making it a more appealing food source than eg the Berry Bush.

Age of Mythology
The Deer returns in AoM, with packs of them wandering the map in Greek territories. They are replaced by Gazelles on Savannah/Desert maps, and Elks on Tundra maps.
