Climate pressures could affect the Rufous Woodpecker’s forest habitats, insect food sources and breeding conditions, highlighting the importance of protecting healthy ecosystems.
The Rufous Woodpecker (Micropternus brachyurus), a medium-sized brown woodpecker found across South and Southeast Asia, has developed several ecological adaptations that help it survive in changing environments. In Bangladesh, the species is recognised as the Rufous Woodpecker, or Khoira Kathkurali, and is currently listed as Least Concern nationally.
The bird is found in a variety of habitats, including evergreen and deciduous forests, scrubland and lower hills. This relatively broad habitat use may provide some resilience when environmental conditions change. The species mainly feeds on ants, termites and other small insects, while it can also take nectar and tree sap.
One of its most unusual survival strategies is its relationship with arboreal ants. The Rufous Woodpecker commonly builds its nest inside the carton nests of Crematogaster ants. Both adult birds help excavate the nest, creating a protected breeding site within the ant colony. This specialised nesting behaviour can help the birds reproduce while using an existing structure in the forest.
Climate change, however, may create new pressures. Rising temperatures, changing rainfall patterns, extreme weather and changes in insect populations can alter the forests and food resources on which birds depend. BirdLife International notes that climate change can force birds to shift their ranges or change the timing of breeding and other activities.
For the Rufous Woodpecker, protecting forests and maintaining healthy insect-rich habitats are therefore important. Although it is not currently considered threatened, continued habitat protection and monitoring can help ensure that this distinctive bird remains part of South Asian forests as the climate changes.
