Scraggles

I'm sure I've seen this wee thing a few times now........super-friendly and doesn't mind in the least about flitting around within an arms reach.   Today I managed to get a slightly better look at him and I'm wondering whether he's either a juvenile or maybe even a semi-leucistic bird.  Either way, he looks pretty scraggly but what he lacks in feather style he makes up for with his lovely loud singing voice.  Hoping he'll return again over the next few days.
