Blyth’s Reed Warbler (Acrocephalus dumetorum) is a tiny brown bird close to the hearts of birdwatchers in the Indian Subcontinent.
Although Blyth’s Reed Warbler breeds across the Eurasian taiga, almost the entire global population migrates to India, Bangladesh and Sri Lanka to spend the winter! During winter, they can be found in any habtat with bushes, even in the middle of big cities, making distinctive “chk chk” calls.
In autumn passage, Blyth’s Reed Warbler migrates slowly through northwestern India on its way south, presumably to capitalize on abundant insect resources in these arid areas after the monsoon rains. But during spring passage, they are thought to pass further northeast of this now barren region.
