How long does it take for baby birds to leave the nest?

Question

I have a robin's nest in my grapes, but i am building a new trellis for them and she has built it on the old one. i dont think it is too safe to move her nest, so i can hold out for a little while. but how long will i have to wait? thanks.

Answer 1

They leave the nest at about 13 days of age.  Please do wait until they leave so there is no chance that the adults will abandon.  Once the babies leave..you can remove the nest and finish the work.

Answer 2

15 to 16 days
