warbles
Trills like birds
Warbles are two different things depending on context.
Most commonly, warbles is the verb form of warble—to sing with trills and melodic variations: The canary warbles in its cage, She warbles an old folk tune.
The word often carries a slightly mocking tone when applied to human singers.
Separately, warbles are parasitic fly larvae that burrow under the skin of cattle and other animals, forming painful lumps.
The condition itself is also called warbles.
