フィールドライファー！ 123種目 (種)ヒシクイ！ 123th field lifer! Bean-Goose!

(訂1)当初オオヒシクイと判断しましたが、その後マガンも飛来し両者の大きさがほぼ同じ事から亜種の同定を諦めました。2025.12.27
(Revision 1) At first, I identified that they were Taiga Bean Geese, but then a Greater White-fronted Goose also flew in, and I gave up the identification of subspecies because the sizes of both were almost equal. 2025.12.27
厚木市２例目でした!Second record in Atsugi city．首の長さ、下嘴の薄さ、嘴の長さからヒシクイではなくオオヒシクイだと思います。

Judging from the length of the neck, the thinness of the lower mandible, and the length of the beak, I think they are Taiga Bean Geese rather than Tundra Bean Geese.
