One of the single most useful creature mods, the homing pigeon won't be carrying your tribe into battle or even scouting out locations -- but it does provide a much-needed service.
This mod lets you place flags as locations, then equip the homing pigeon leg ring on any of your flying beasts. You can manually recall any flyers to the flag, or when you die, your "pigeon" will automatically return to the flag location.
No more losing your dumb flyers who get eaten while randomly wandering around! The tribe log is also updated when the flyer is recalled, letting your tribe know what happened so everyone is well informed of player activity.
