It feeds in the tops of trees, so can be quite tricky to see, but its series of loud whistles will usually give away its identity.
Nuthatches also have a unique talent – they’re the only bird in the UK that can climb down a tree trunk beak first! Its dagger-like beak is characteristic and you might see one in a garden, especially in the winter.
Take care though, nut-watchers, Nuthatch behaviour can be confused with that of the Treecreeper. It’s a similarly sized bird that likes to scamper up the side of trees in search of insects before flying back down.
