English: The chestnut-headed tesia, a petite insectivorous songbird once classified within the "Old World warbler" family but now assigned to the bush warbler family, presents an endearing sight with its compact, tailless form. Its striking combination of a luminous white eyering, deep cinnamon-brown head, and vibrant yellow throat renders it unmistakable in appearance. This avian species thrives in montane and hill forests, particularly favoring densely vegetated wet or damp areas, often found near streams and gullies. During winter, it retreats to scrubby forest and forest edge growth in lower foothills. With an active foraging style within the safety of deep cover, it rarely ventures into open spaces. Its vocalizations include a distinctive loud, fluid-sounding “chee-leu-chee-wit,” accompanied by various sharp and high-pitched calls. Recently, This bird was sighted at the Buxa Tiger Reserve & National Park in West Bengal, India.
