秋ヶ瀬公園のコマドリ, Japanese robin of Akigase Park
ウグイスやオオルリと共に日本三鳴鳥のコマドリ, Japanese robin, one of the three Japanese songbirds together with Japanese bush warbler and Blue-and-white flycatcher
ピクニックの森に行くと、野鳥写真撮影グループの姿が見られた。尋ねると、コマドリがいると言う。
When I went to the picnic forest, I saw a wild bird photographer group. On asking, they said that there was a Japanese robin.
コマドリのオスが近くの木の枝に舞い降りてきた。
A male Japanese robin flew down and rested for a while on a nearby tree branch.

森の中からコマドリの美しいさえずりが聞こえていた。そのコマドリが近くの木の枝に降りてきたのは餌で呼び寄せたためだった。
I heard a beautiful chirping of a Japanese robin in the forest. It was because the bird came down to the branches of the nearby tree by bait.

コマドリはまず藪の中に降りてきて様子をうかがっていた。そして餌の置いてある木に飛び移った。 やはり2，3秒間静止して様子をうかがってからコマドリは餌に近づいた。
The Japanese robin flew down first in the bush and looked around. Then it jumped to the tree on which the bait was placed. After waiting for a couple of seconds, the bird approached the bait.
コマドリは数秒間静止して様子をうかがっているので写真を撮りやすかった。コマドリはウグイスやオオルリと共に日本三鳴鳥の1つだそうだ。
The Japanese robin kept still for a few seconds to look around, so it was easy to take photos. It is said that the Japanese robin is one of the three Japanese songbirds together with Japanese bush warbler and Blue-and-white flycatcher.

Japanese robin
The Japanese robin (Larvivora akahige, formerly Erithacus akahige) or komadori is a small passerine bird in the family Muscicapidae.
The name “Japanese robin” is also sometimes used for the red-billed leiothrix (Leiothrix lutea). The specific name akahige is, somewhat confusingly, the common name of its relative Larvivora komadori in Japanese.
The Japanese robin, together with the Ryukyu robin and the European robin, was previously placed in the genus Erithacus . A 2006 molecular phylogenetic study found that the two East Asian species were more similar to the Siberian blue robin, at the time in Luscinia than to the European robin. In 2010 a large study confirmed this result and also found that Luscinia was non-monophyletic. The genus Larvivora was therefore resurrected to accommodate a clade containing the Japanese robin, the Ryukyu robin, the Siberian blue robin, and several other species that had previously been placed in Luscinia.
