(edit) just a few bird ideas
say i train a bird (in a cage possiablly) then i attach it to my wheel barrow (or what ever item i tend to lose all the time)
now when i lose my barrow (cause 100% will happen daily lol)
i click and use bird and it flys towards barrow and kinda flys around till i get close and then bird flys away or something
With the messager bird idea we can hold races based on stats breed into bird mabye
But also chould train to spot people in area
Release bird it flys off, if it spots someone nearby it panics ( fairly noticeable to the person spotted) and flys back to owner in panic mode showing direction spotted (based on unreliable accounts of pigeons spotting snipers in Vietnam war)
Different training method then other
Release bird 50% chance will fly away, if does return get little more trained, making it better at spotting and lower chance to fly away
