Little ringed plover, Kochidori, コチドリ

This is first installment of a two-part series of this topic.

 Subspecies of the little ringed plover come to Japan as a summer migrant bird, and breed.
I observed this family for three days from the day just left the nest.
And, injury feigning act that is peculiar to little ringed plover was also frequently observed during three days.
Injury feigning or broken wing act:
When the enemy approaches, spread the wings and bend and bend and pretend to be injured (injured), leave the nest and deflect the attention of the enemy.
 このシリーズ2回のうちの1回目のアップロ―ドです。
亜種コチドリは日本に夏鳥として渡ってきて繁殖します。
コチドリの家族を、巣離れした日から3日間観察しました。そして3日間コチドリ特有の擬傷がたびたび観察されました。
擬傷:
寒外敵が近づくと翼を広げて身を屈め傷つたふり(擬傷)をして巣から離れ、外敵の注意を反らします。
