One of the UK's less frequently seen Tit species. Hard to distinguish from the Willow Tit with subtle differences in shape colour and song. Not distinguished from the willow tit as a separate species until 1897, the marsh tit is smart, clean looking bird with a small, well defined black bib and glossy black cap. As with so many woodland birds, its call is the best way of locating it. It feeds acrobatically and will hoard food if it finds a good supply. Recent population declines make this a Red List species.
