Thanks.
Licensing is a bit of a process, not too daunting but in a nutshell.
You'll need to be of good character.
You will need 2, good referees and one of them is, or has been Schedule 1 licenced previously.
You need to provide some images of birds, I had to provide at least 2 of adults feeding young, though this isn't species specific. Your referees have to do the same. This demonstrates to the licensing authority that you have some idea of what you're doing.
You have to keep records if you do get a licence and provide a return at the end of the year.
That's the short version, there is a bit more to it but that will give you some idea.
