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.[3][4]
Clements has separated the Izu robin, Larvivora tanensis, into a distinct species.
Description
The Japanese robin is about 14-15 centimeters in size.[5] This bird species is mainly gray and bright orange.[6] The male Japanese robin is olive brown from the top of the head to rump, with an orange face and neck, and a grey breast and underside. Their tail is reddish-brown, their legs are pinkish brown, and they have a black bill. The female Japanese robin looks very similar to the male, but their orange and brown color characteristics are much duller and less extensive. The juvenile Japanese robin also looks very similar to the adult, but has dark spotting on the breast, pale rufous feathers from crown to mantle, and a rufus buff.[7]
Habitat
The Japanese robin lives in natural habitats such as islands, lakes, mountains, and
The Japanese robin is an abundant species of robin from the islands of Japan. The Japanese robin, along with the Ryukyu robin, can be traced back to 1835 when they were placed into one of the Coenraad Jacob Temminck's works under the name Erithacus akahige. After the 2006 molecular phylogenetic study, the species was placed into a clade under Larvivora, meaning "caterpillar eater," giving it half of its current scientific name.[9]
Diet
The Japanese robin, as hinted by its scientific name meaning "caterpillar eater," is known for feeding on beetles, insects, milled worms, small crickets, fruits, and other small insects. Given their diet, they are considered omnivorous.
Reproduction
The Japanese robin reproduces throughout May and June in central Japan.[10] Their nest typically consists of moss, twigs, dry leaves, ferns, and roots. When the female is ready, she lays about 3-5 eggs of greenish color, one egg per day, and incubates them for roughly 2 weeks. Once born, the young chicks are nurtured for a month, or 31 days, before they leave the nest and become independent. The robin does not mate for life and only finds a partner during the spring mating season.
Bird song
The Japanese robin can be considered a small songbird; however, it has a single note that is extremely loud at first, but tones down throughout the song. The robin's call is similar to a telephone ring: well-spaced and simple phrases, along with short chattering. Females tend to sing during nest building and during the incubation period. Males will sing, but their frequency will drastically reduce once eggs have been laid.[11]
