Birding report at Choshi Fishing Port
Iceland Gull (thayeri)
Scientific Name Larus glaucoides thayeri
3号＆カナダ個体1
個体1
4wかもしれない
カナダカモメ個体2
P10のミラーが先端に達し、P9のミラーは外弁にも及び、初列の黒色部は5枚だが、クムリーンとの中間個体と言えるのか？
Note
8:30～16:00 毎年一回は行くことにしている銚子に今年も行ってきた。カナダadしか見つけられず、何の成長もしてないことを確認。時々沖も眺めていたが、アホウドリ類は現れず。沖を飛ぶウだと思っていたのはアビ類だったかも？ ※カムリ変更のため上げ直し。この個体がそうであるとはまだ分からないが、3号は私と同い年（2008年生まれ）のカモメである。
