Young Wirebirds fledge when 5-6 weeks old, but may stay within their natal territory for some time afterwards. Wirebirds in their first year tend to range much farther than adults. Little is known about rates of breeding success in the Wirebird. These are very rough estimates, however. It is known that Wirebirds may nest more than once in a year but there is no information on what proportion of the population do so, neither is it known how frequently lost clutches are replaced.
Feral cats are probably the only potentially significant predators of full-grown birds.
In the absence of a major predation problem mortality could be expected to be low and adult Wirebirds to be relatively long-lived. Hopefully the current ringing programme will provide more information on survival rates and longevity.
