How many times does a tree-creeper bird nest in a season?

I am waiting to paint my shed and a tree creeper has built a nest near it .I dont want to disturb it but I wondered how long it will be?

How many times does a tree-creeper bird nest in a season?
In a good season weather permitting and the supply of insects ,a Treecreeper,(Certhia familiaris) will breed twice,


it takes from 14 -16 days for the eggs to hatch and 12-14 days for the young to fledge and leave the nest,they will occaisionally return to the nest to roost for the night but once again it depends on the weather.
Reply:They incubate for 13-17 days, and chicks leave the nest between 14-17 days of age. Once they leave the nest, they will no longer have any use for it. If the adults have a 2nd nest (this species occassionally does) they would build a new nest elsewhere.
