The Marsh Tit is a small, mainly brown bird, with a shiny black cap, dark bib and pale belly. In the UK, its identification is made tricky by the very similar appearance of native Willow Tits. They're so hard to identify that ornithologists (scientists who study birds) didn't realise there were two species until 1897.

Ornithology is such a fascinating field! It's amazing to think that it took until 1897 to distinguish between Marsh Tits and Willow Tits. Nature always has a way of surprising us with its intricacies.
