キジの母衣打ち, Male pheasant’s special performance to hit the body by the wings.
キジは草の茂る土手に上った。キジは突然羽を広げて「ケーン」と大声で鳴き、「母衣打ち（ほろうち）」動作をした。この場所がこのキジの縄張りらしい。
The pheasant went on the bank where the grass grew thick. The pheasant suddenly opened the wing and called out with “Cane”, and performed the special action to hit the body by the wings. This place seems to be the territory of this pheasant.
土手の下の池にコブハクチョウが泳いできた。キジは土手にうずくまっている。警戒したのだろうか？
写真を撮っていると、地元のおじさんが近寄ってきて教えてくれた。「裏山にゴルフ場があって、時々キジが現れるから捕まえて沼の土手に放したら増えているみたいなんだ。ほら、そこに白鳥の巣もある。」
A Mute swan swam in the pond under the bank. The pheasant crouched down on the bank. Is the pheasant cautious?
When I was taking photos, a local person came and told me: “There is a golf course in the mountain behind and sometimes the pheasants appear, then we caught them and released in the bank of the pond. The pheasant seems to be increasing here. Hey, there is the nest of the swan there, too.”

山地から平地の林、農耕地、河川敷などの明るい草地に生息している。地上を歩き、主に草の種子、芽、葉などの植物性のものを食べるが、 昆虫やクモなども食べる。繁殖期のオスは赤い肉腫が肥大し、縄張り争いのために赤いものに対して攻撃的になり、 「ケーン」と大声で鳴き縄張り宣言をする。その後両翼を広げて胴体に打ちつけてブルブル羽音を立てる動作が、 「母衣打ち（ほろうち）」と呼ばれる。メスは「チョッチョッ」と鳴く。

The green pheasant (Phasianus versicolor), also known as Japanese green pheasant, is native to the Japanese archipelago, to which it is endemic. It was formerly considered to be a subspecies of the common pheasant. It is the national bird of Japan. The male (cock) has dark green plumage on the breast, neck, mantle, and flanks. The male also has bluish-purplish hood with clear ear-tufts, red wattle, and long, pale grey-banded tail. The female is smaller than the male, with a shorter tail, and has brownish black colored plumage, with dark brown feather fringed pale brown.
