noun
olivaceous piculet
A species of bird (Picumnus olivaceus). This is a specialized ornithological term; the name is typically written in katakana.
オリーブヒメキツツキは中南米に生息する小型のキツツキです。
The olivaceous piculet is a small woodpecker that inhabits Central and South America.
The name is a compound of オリーブ (olive, from English) + 姫 (hime, 'princess', here used as a diminutive prefix for small birds) + 啄木鳥 (kitsutsuki, 'woodpecker'). The exact derivation is uncertain, but it follows a common pattern for Japanese bird names.
