Japanese Tit

Parus minor

The Japanese tit (Parus minor), also known as the Oriental tit, is a passerine bird which replaces the similar great tit in Japan and the Russian Far East beyond the Amur River, including the Kuril Islands. Until recently, this species was classified as a subspecies of great tit (Parus major), but studies indicated that the two species coexist in the Russian Far East without intermingling or frequent hybridization.The species made headlines in March 2016, when Suzuki et al. reported in Nature Communications that they had found experimental evidence for compositional syntax in bird calls, marking the first such evidence for that type of syntax in nonhuman animals.
