The Japanese tit, known scientifically as Parus minor, is a passerine bird that is closely related to the great tit. It is also referred to as the Oriental tit.
This species is similar in appearance to the great tit but is recognized as a distinct species. It can be identified by its vibrant plumage and the distinctive markings on its head and chest.
The Japanese tit inhabits various woodland environments in Japan and the Russian Far East, extending its range beyond the Amur River and including the Kuril Islands.
The distribution of Parus minor is primarily within Japan and the Russian Far East, where it replaces the great tit.
The Japanese tit exhibits complex behaviors, including the use of compositional syntax in its calls—a remarkable trait that has been the subject of scientific study.
In a groundbreaking study, it was found that the Japanese tit uses a form of compositional syntax in its calls. The species responds to the recruitment call of the willow tit only if it follows the Japanese tit's alert call in the correct sequence, showcasing their ability to recognize the structure of calls.
Until recent studies, the Japanese tit was considered a subspecies of the great tit (Parus major). However, it has been observed that the two species coexist in the Russian Far East without intermingling or frequent hybridization, indicating clear species separation.
