Some populations of Chestnut-headed Bee-Eater (Merops leschenaulti) are strongly migratory while others show no more than local movements.
Populations that breed along the Himalayan foothills leave the area during winter. Where they go is still a mystery but some evidence suggests that they may be moving to hill forests in South India. Both in autumn and in spring, Chestnut-headed Bee-Eaters are seen in passage in the plains of South, central and North India, indicating considerable north-south movement.
