アオジより稀にしか見られないクロジ, Grey bunting, the rarely-seen bunting compared with Black-faced bunting.
2018年12月31日、水元公園を散歩した。公園の林でクロジを見た。クロジとアオジが餌場に現れたので2種の羽毛の色の違いが分かる。
On December 31, 2018, I strolled in Mizumoto Park. I saw Grey bunting in the forest of the park. A Grey bunting and a Black-faced bunting appeared at the feeding place and then the difference in feather color of the two species can be seen.

日本では亜種アオジが北海道や本州中部以北で繁殖し、中部以西で越冬する。また少数ながら基亜種が越冬（冬鳥）や渡りの途中（旅鳥）のため、主に本州の日本海側や九州に飛来する。

The black-faced bunting is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. It breeds in southern Siberia across to northern China and northern Japan. It is migratory, wintering in north-east India, southern China and northern south-east Asia.
