When Hirokazu finds out he's an accidental lolicon.
Anyhow, bird lifetime is all over the place. Robins and sparrows and doves are lucky to get 6 years in the wild but can do just over 20 in captivity if they're lucky. 15 for pigeons. Crows are similar though one allegedly reached 59 but there's no actual proof (India, someone might have been swapping out crows).
Larger parrots can do up to 80 (well documented). But birds like Rin-san more in the 20s. Now the good news is that generally the larger the bird the longer it lives. Large parrots live way longer than small parrots. Ostriches can do 40-50 in perfect conditions. And Rin is really really big for a bird.
