千葉の親戚宅から帰るついでにYさがし。
温かい雨のあとはミミズが地表近くに出ているためか、よく動き回っていた。
なぜかキジバトが採草地の真ん中で寝ていた。

前からやりたかった場所でバンディングお手伝い。狙いの鳥はそこそことれた。
やはり夕方に活性化するのを、アシ原の中で実感した。
網場の周りは猛禽ランド化しており、なかなか楽しめた。
小耳は個人的に当地初確認。毛足とバトル。

ぬるい小雨。タゲリの群れの中に大橋4つ。肩羽のあたりが一部夏羽に換羽中だった。
野焼き後にツグミとタヒバリがうじゃうじゃ。ああ、某所では何で焼いてくれなかったんだ。

1月ぶりに調査地をぶらぶら。ヒドリ1つとコガモ2つを回収。なぜかこの時期はコガモの引っかかっている個体数が多い気がする。ミコアイサが初記録。
タゲリを初回収。♂1w。翼式が性判定に使えるのを初めて知った。♂の方が翼が丸い。この個体はP8>P7>P6=9>P5>P4=P10。
Yは複数いたようが、いずれもすぐに飛去。
