haha, then he should be avoid any Pin. I think he won't fly :P
This bird is a robin usually found in the United Kingdom, they are fairly small and nothing like the robins we have in Canda or the USA which are basically larger sized starlings with a reddish breast.
It looks like the person who created this animation made the robin a lot more round and fatter than it actually is.
Oddly most pictures of these cute little birds I've seen usually show them to be quite bulbous or round.
