|Despite what you see here, to me it actually looks bigger than most adult robins.
I believe it's an adult.
It doesn't fly away. I don't know if it's injured or what.
The pictures are grainy because I couldn't get too close to it before it hopped away, but it wouldn't fly away. It's otherwise trapped/protected inside my totally fenced garden, enjoying a schmorgasboard of slugs and worms and buggies.
So, because it does seem to be eating slugs, I'm really happy to host him/her, but I'm concerned that it might be sick. Any suggestions?
