The blackbird with a blue neck band is most likely the Eurasian Blackbird (Turdus merula), particularly the male, which can exhibit a blue sheen around its neck. However, if you're referring to a specific bird, it may also be a local variant or species. The blue neck band can be a result of light reflection on the bird's feathers, giving it a striking appearance. In some regions, other species may also display similar features, so context matters for accurate identification.
