Do I need to add a final nest visit to my attempt?

Adding a final nest visit to your attempt showing there are zero live young in the nest is a great way to help confirm your nest outcome. This shows that the nest was indeed empty and the nest is again inactive.

Note: you should only be reporting the number of eggs and young that are inside the nest (or nest box), so if you see fledglings out on your lawn but none in the nest itself, the appropriate nest visit entry would record “0” young.
