thrush
Synonym discussion
Sense: noun/1
These bird names overlap in everyday talk, but they point to different kinds of garden birds. A thrush is usually a brown songbird with a paler chest that often shows spots. A sparrow is smaller, plainer, and more strongly associated with streets, roofs, and feeding near people. A robin is easy to recognise because of its red or orange breast. A blackbird belongs to the same larger bird family as many thrushes, but learners usually picture a darker bird, especially the black male common blackbird. If you hear a rich repeated song from a brown bird with a spotted chest, thrush is the best choice.
Etymology
English has two nouns spelled thrush. The bird name goes back to Old English thrysce, from an older Germanic bird-name. The medical sense appeared much later and is probably linked to a Scandinavian word for a mouth disease. The two senses now share one spelling in modern English, but they did not start as the same historical word.
