The Yellow-browed Warbler (Phylloscopus inornatus) has become an increasingly common autumn migrant to the UK. Originally considered a rarity, its numbers have grown significantly in recent decades, especially in the late summer and autumn (mainly September to October and mostly on the east coast). The birds breed in Siberia and typically migrate to Southeast Asia for winter. However, a growing number stray westward during migration and end up in the UK.

There have been a few documented cases of overwintering individuals, particularly in the southwest of England. The species has expanded its range, and birdwatchers now expect to encounter it along the east coast of the UK during migration periods.

Factors influencing this rise might include climate change, changes in migration patterns, and the possibility that the UK’s mild winters are becoming more suitable for the species.
