ひたき

• (Tokyo) ひたき (Heiban – )^[1]
• IPA^(key):

Referred originally just to the 尉鶲 (jō bitaki, “Phoenicurus auroreus or Daurian redstart”), later came to refer to a number of visually similar species.

Likely a shift from 火焚き (hitaki, “lighting a fire”) below, from the characteristic call of the bird, which resembles the sound of striking a flint against a firestarter.^[1][2][3]
