I think its a Coal Tit and loads of them at home in Omeath and I have often counted 7 or 8 Great Tits at one time on feeders or sitting on the shed wall. Heaps of Blue Tits too and two Dunnocks about all the time. I have one identical to first photo in my garden here all winter so wondering is Coal Tit correct. They are a lovely little bird and mine has a lovely burnt orangey colour on it. I also have three Dunnocks who never leave and one is larger than others with much greyer head and black stripey sides. All the lovely Redwings still here, I wonder will they disappear in the good weather.
