These scarlet-breasted woodpecker species are distributed in India (northeast), Nepal, Bhutan, China (southeast Tibet) and Myanmar.In India, these species are distributed in the states of Sikkim, northmost West Bengal, Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur and Mizoram.
The nominate subspecies D. c. cathpharius is distributed in central and east Nepal, Bhutan and India (Sikkim, northmost West Bengal, Assam and Arunachal Pradesh).
The subspecies D. c. ludlowi is distributed in southeastern Tibet (China). The subspecies D. c. pyrrhothorax is distributed in India (Assam, Meghalaya, Nagaland, Manipur and Mizoram) and western Myanmar.
Ecosystem and habitat
These scarlet-breasted woodpecker species have high forest dependence. They normally occur in altitudes from 1200 to 3000 meters.The natural ecosystems and habitats of these woodpecker species include tropical and subtropical moist montane forests, broadleaf evergreen forests, tropical and subtropical moist lowland forests and deciduous forests.
Diet and feeding behavior
The diet of these scarlet-breasted woodpecker species consists mainly of insects. Wood-boring insects, insect larvae, spiders, beetles and nectar are their primary food.Reproduction and breeding habits
The breeding season of these species is during April and May in most of their range. These species are mostly monogamous. They excavate nest holes in tree trunks. The clutch contains 2-4 white eggs.Migration and movement patterns
These scarlet-breasted woodpecker species are non-migratory resident birds. The populations in the higher altitudes descent to the lower levels in winter.Post breeding, the resident juveniles may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.
