Spot the difference

I've been chatting recently with a new to me fellow Blipper (Lindee from across the pond) - about the similarities & differences in our respective bird species.
I for example didn't know that there is a white breasted nuthatch - or a variation in the Tit family called a Chickadee - Lindee tells me that the Nuthaches I'm used to are infrequent & fast visitors to her garden - whilst mine are abundant, here most days & quite brazen!
Recently the long tail tits have appeared & seem to like what they've found as they've stuck around. They've always been in the area - just not in our little wood before.
