I don't know if it's an intended action or not, but whenever I leave my birdcage unattended/unused for a while, the bird seems to die. I've been away from the bird cage whenever this has happened, but everytime I've returned, my bird is gone. I think we actually have to feed it, now?
Right. He can barely survive a day long. That means if you plan on staying somewhere over night, you need to take him with you. After all I dont like to do that, cause seeds and the bird itself need inventory - thats why I simply catch a new bird with a bird trap, those are pretty cheap.
But yea... in caves that will EXTREMELY affect my way of making use of all the monster meat there. A dead bird would usually force you to retreat to the surface and get a new one. Also underground you ain't find any seeds, so your time will be limited anyways.
Good bye caves, in RoG I can't handle you anymore >:(
