I love that the forest ghost has friends. Although he seems to be a secretive creature, I am now reassured he is not lonely. I would love to give you a helpful tip with gimp etc... but sadly I have no idea. I am not very good at image editing.
I wish you all the luck that your plans to help the sparrow population will be realized. As I have written in an earlier comment, I also love little animals (ok... and big ones :-D) Around here we have a problem to protect moles and common hamster who are endagered of becoming extinct, which is so unbelivable sad.
I hope you are well ( I have a sh*** headache day again)
love simone
