This is certainly a strange little bird. Sort of drab and small and always moving but then every once in a while, usually when excited, the male will flash a dash of red feathers which are normally hidden on top of his head. What that happens you get a huge reward for following this little guy as normally, you can't see any red at all. Three of the shots above show the red feathers. Otherwise, he sort of looks like a drab version of an American Goldfinch to me.
