So, TPC if the little guy, who's looking pretty restless, decides to fledge and gets grounded or stuck somewhere on a roof and has to be retrieved, would you put him into the nestbox after banding (assuming he is uninjured and ready to be put back) leaving the girl on her own on the ledge?
And will you be naming these guys? I know we won't be able to keep track if they can't be banded, but it would be fun to call them something other than boy bird and girl bird
