Etymology: The word has two unrelated lives in English. In the sugar industry, a "calandria" is a machine of cylinders, first recorded in 1886, and the name comes straight from Spanish, where "calandria" meant a machine with cylinders. The same Spanish word also named a bird, the lark, and English later borrowed that sense too. Two separate borrowings, one spelling. The bird sense is the older of the two in Spanish, and it is what English speakers most often meet as a South American mockingbird with a black head, known scientifically as Mimus modulator or Mimus orpheus. The industrial machine simply reuses the Spanish term, which is why an engineer's heat exchanger and a songbird share a name.
