The Great Tit (Parus major) is native to the Palearctic region. Its geographical distribution includes Europe, the Middle East, Central Asia, and parts of North Africa. Specifically, the species is widespread throughout continental Europe, extending into Scandinavia, Russia, the Caucasus, the northern part of the Arabian Peninsula, and Central Asia, reaching as far as the Amur River and the Khabarovsk region.

The Great Tit typically inhabits woodlands and forests, but it is highly adaptable and can also be found in gardens, parks, and urban areas. It prefers deciduous or mixed woodlands with a dense canopy, but it can also thrive in coniferous forests. The climate in these regions varies from temperate in Europe to more arid conditions in parts of the Middle East and Central Asia.

As an omnivorous bird, the Great Tit occupies a versatile ecological niche. It feeds on a diverse diet ranging from insects and spiders to seeds and fruits, particularly during the winter months. It is known for its adaptability to various environmental conditions, which allows it to thrive in both rural and urban settings. This adaptability is evidenced by variations in plumage color and size across different regional populations, which may reflect adaptations to local environmental conditions.
