reed bunting
A small passerine bird (Emberiza schoeniclus) found in wetlands; the name is typically written in katakana.
In winter, reed buntings come to the reed beds.
Kanji form is rare and mainly used in older or specialized contexts; learners should use the katakana form.
The name オオジュリン is likely derived from the bird's call or appearance, but the exact origin is uncertain.
