Hi all, I'm pretty sure this is a willow tit as I couldn't see any pale spot on the bill, and there is no contrast between the cheek and the nape (from what I have researched these are the most reliable characters). Unfortunately the bird was basically silent and only gave one short note, but it did sound quite nasal as willow tits tend to
Also this was in manchester, and willow tits are far more common here. Regardless it would be nice to hear others opinions about it so I can be sure, as this is the first time I've seen a marsh/willow tit
