Cockatiels are picky when choosing a mate and form strong bonds that last for life. Breeding usually occurs following a heavy rain, when food will be plentiful for the chicks. During the rain, many of the birds will sit with their tails and wings outstretched to bathe.
Wild Lifespan. In their natural wild habitats, cockatiels, on average, live between 10 and 14 years, indicates Animal Diversity Web via the University of Michigan. Their average age for passing away is younger in the wild than it is in captivity. Captive Lifespan Cockatiels that are kept as pets -- or that live in other captive settings -- can stay alive for up to 25 years or so.
