Greenish warbler

The greenish warbler is an enchanting small bird native to northeastern Europe and regions of temperate to subtropical Asia. During the winter, it migrates to India, occasionally surprising bird watchers by making appearances in Western Europe. Belonging to the Phylloscopidae family, this leaf warbler is easily identifiable by its grayish-green and off-white plumage.

When it comes to breeding season, the greenish warbler favors lowland deciduous or mixed forests and primarily feeds on insects. A particularly fascinating aspect of this bird lies in its evolutionary journey. It boasts several subspecies that have spread east and west of the Tibetan Plateau. While some of these subspecies interbreed, others exhibit clear genetic distinctions.

One of the most remarkable features of the greenish warbler is its song. Depending on their geographical location, certain populations produce long, melodic tunes, whereas others incorporate distinctive up-and-down slurred notes.
