Varied Tit: A Detailed Look at the Colorful Sittiparus varius
The varied tit (Sittiparus varius) is a striking perching bird belonging to the Paridae family. Found across the eastern Palearctic, this species is a common sight in Japan, Korea, and parts of northeastern China and southeastern Russia. Known for its distinct plumage and intelligent behavior, the varied tit is a fascinating subject for ornithologists and nature enthusiasts alike.

Key Facts
- Scientific Name: Sittiparus varius
- Family: Paridae (Tits)

Taxonomy and Scientific Classification
The history of the varied tit's classification reflects the evolving nature of biological science. Originally described in 1845 by Dutch zoologist Coenraad Jacob Temminck and German ornithologist Hermann Schlegel, it was initially placed in the genus Parus.
As molecular phylogenetic studies—research that examines evolutionary relationships through DNA—advanced, the classification shifted. In 2005, mitochondrial DNA research suggested moving the species to the genus Poecile. However, a 2013 study analyzing both mitochondrial and nuclear sequences led to the adoption of the genus Sittiparus by the International Ornithologists' Union. This genus was originally established in 1884 by Edmond de Sélys Longchamps, with the varied tit serving as the type species.
Species and Subspecies Evolution
Taxonomy is not static. While several birds were once considered subspecies of the varied tit, a 2014 phylogenetic study promoted the following to full species status:
- Owston's tit (Sittiparus owstoni)
- Iriomote tit (Sittiparus olivaceus)
- Chestnut-bellied tit (Sittiparus castaneoventris)
Currently, five living subspecies are recognized, though one—the Daito varied tit (S. v. orii)—became extinct around 1940.
Physical Description and Habitat
The varied tit is a small bird, typically measuring between 12 and 14 cm in length and weighing approximately 16 to 18 g. Its appearance is characterized by a complex pattern of colors:
- Head and Throat: The crown, bill, throat, upper breast, and nape are black, often marked by a thin white central line running from the crown to the nape.
- Face: The forehead, face, and cheeks are white.
- Body: The back, wings, and tail feature a bluish-grey hue, while the mantle, lower breast, belly, and undertail coverts are a rich chestnut color.
- Feet: Dark grey.

These birds thrive in diverse forest environments. Their preferred habitats include open mixed forests containing Japanese Castanopsis and Japanese larch, as well as coniferous forests featuring Japanese yews, Cryptomeria (sugi), and pines. They are also frequently found in bamboo forests located on mountain slopes and in river valleys.
Diet and Behavior
The varied tit maintains a mixed diet to sustain its energy levels, consuming both seeds and insects, with a particular preference for caterpillars. Their vocalizations are subtle, consisting of tiny tones that sound like "tzu....tzu....tzu..."
Cultural Significance in Japan
In Japanese culture, the varied tit is known for its intelligence and has been featured in a unique performance known as omikujihiki. In this display, the birds interact with a small model Shinto shrine. They have been observed depositing coins, ringing bells, opening doors, and using their beaks to cut strings or tape to retrieve omikuji (fortune-telling slips).

Frequently Asked Questions
What does the varied tit eat?
The varied tit has a mixed diet that includes both seeds and insects, specifically caterpillars.
Where can I find the varied tit in the wild?
They are located in the eastern Palearctic region, specifically in Japan, Korea, northeastern China, and the southern Kurile Islands of Russia.
Is the varied tit an endangered species?
No, according to the IUCN Red List, the varied tit is classified as Least Concern.
What is "omikujihiki"?
Omikujihiki is a cultural show in Japan where trained varied tits interact with a model Shinto shrine to retrieve fortune-telling slips (omikuji).
How has the classification of this bird changed?
Originally placed in the genus Parus, DNA studies led to its placement in Poecile, and eventually, it was moved to its own genus, Sittiparus.
