About Great slaty woodpecker
The great slaty woodpecker (Mulleripicus pulverulentus) is a remarkable bird species distinguished by its immense size, holding the title of the largest confirmed living woodpecker. This species is found across a wide range encompassing the Indian subcontinent and Southeast Asia, inhabiting primary forests with large, mature trees. Its presence is a key indicator of healthy, undisturbed forest ecosystems.
Description and Identification
Measuring between 45 to 55 cm in length and weighing up to 563 grams, the great slaty woodpecker is an imposing avian. Its plumage is predominantly a dark grey or blackish slate-grey, often adorned with small white spots on the head and neck, and a paler, sometimes yellowish, throat. Males are further distinguished by a small red moustache. Distinctive features include a very long and strong chisel-tipped bill, an elongated neck, and a long tail, which, along with its sheer size, readily sets it apart from other bird species, sometimes leading to initial confusion with hornbills.
Habitat and Distribution
This species thrives in primary semi-open, moist deciduous, and tropical evergreen forests. It shows a preference for areas with sprawling stands of large trees like dipterocarps and teak, as well as mature sal forests, swamp forests, and mangroves. While usually found below 600 meters, it can inhabit montane areas up to 1,100 meters and occasionally even higher. Its range extends across Bangladesh, Bhutan, Brunei, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, the Philippines, Singapore, Thailand, and Vietnam.
Ecology and Behavior
Great slaty woodpeckers are often observed in groups of three to six individuals, typically comprising a breeding pair and their older offspring. Their diet primarily consists of social insects such as ants and termites, along with insect larvae, which they extract from tree nests. Foraging involves gleaning, probing, pecking, and hammering into wood, with their long necks and bills allowing them to reach into crevices. They are known to fly considerable distances between foraging sites. Unlike many large woodpeckers, their voice is relatively weak and quiet, consisting of whinnying cackles and single calls. Breeding pairs are believed to maintain lifelong bonds and may raise young cooperatively. Nests are excavated in large trees, often at significant heights.
Conservation Status
The great slaty woodpecker is currently listed as Vulnerable on the IUCN Red List. Its population is in decline due to extensive habitat loss, particularly the logging of old-growth forests, which are crucial for their survival. Reductions in population density of over 80% have been observed in logged forests, highlighting their dependence on pristine forest environments.

What kind of habitat does the great slaty woodpecker prefer?
The great slaty woodpecker favors primary semi-open forests, including moist deciduous and tropical evergreen forests. They are often found in areas with large, mature trees, such as dipterocarp and teak stands, as well as sal forests, swamp forests, and mangroves.
What does the great slaty woodpecker eat?
Their diet primarily consists of social insects such as ants and termites, as well as the larvae of various insects. They are often observed foraging on the nests of these insects found in large trees. Small fruits may occasionally supplement their diet.
Why is the great slaty woodpecker considered vulnerable?
The great slaty woodpecker is classified as Vulnerable due to the significant loss of forest cover and the logging of old-growth forests across its range. Their dependence on large, old trees for feeding and nesting makes them particularly susceptible to habitat degradation.
