Great Tit,
Parus major
The Great Tit was the most common songbird I saw in the trees of Clissold Park during the two weeks of late December that I visited the park almost daily while staying in nearby Islington during a London winter vacation. I also saw many Blue Tits, one Long-tailed Tit, but as far I as was able to tell, no Coal Tits. These little birds, more colorful and melodious than our North American chickadees, are one of the constant and delightful features of parks and gardens in the UK. The male Great Tit, shown above, has brighter yellow underparts and a broader black chest strip than the female, shown in the three photos below.
