The bar-tailed treecreeper (Certhia himalayana), or the Himalayan treecreeper, is a species of bird in the family Certhiidae. It is found primarily in the northern parts of the Indian subcontinent, particularly in the Himalayas, as well as in adjoining regions. It is found in Afghanistan, India, Iran, Kazakhstan, Myanmar, Nepal, Tibet, Russia, Tajikistan, Turkmenistan, and Uzbekistan.
Its natural habitats are boreal forests and temperate forests. The bar-tailed treecreeper has a flecked or striped feather pattern, usually in black, brown, white and red hues. This coloration allows the treecreeper to blend in with its forest surroundings quite well. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bar-tailed Treecreeper is recorded against all the birds logged in Dehradun (211 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
