You should very rarely help animals unless in immediate danger, especially protected species.
We had a young blue tit clinging on to a bit of shrubbery yesterday crying for it's mum. Wife wanted to move it in case a cat or bigger bird came along but I said no, lets just keep an eye from a safe distance. 5 minutes later mum is in a neighbouring bush 'shouting' at it but it wouldn't move until she came closer. Both eventually took off after about 20 minutes with mum still berating/encouraging the youngster.
