The grandala (Grandala coelicolor) is a species of bird in the thrush family Turdidae. It is the only species in the genus Grandala. It is an insectivore and frugivore. It ranges across the northwestern and northeastern Indian subcontinent and northeast to western China, existing primarily at high to very high altitudes in the Himalayas and the Tibetan Plateau. It is found in Bhutan, India, Myanmar, and Nepal, as well as Tibet and other areas of China north to southeast Gansu.
The body length of the grandala is 19-23 cm, and it weighs from 38–52 g. The plumage of the male is intense dark blue, with the tail and wings blacker. The plumage of the female is greyish-brownish with fine white streaks on the underparts; rump greyish-blue; the tip and underside of the wing feathers are white. Birds usually make the sounds "dew-ee" and "dewee". In young birds, the plumage is similar to females, but does not have a bluish tint on the rump and upper tail integuments.
Grandala is a social bird; they feed on insects, and small fruit such as Vaccinium berries. The grandala is a partial altitudinal migrant, breeding in high alpine scrub and meadows... Wikipedia →

Rare
Under 5% of wildlife watchers report a Grandala sighting in Langtang National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 175th most-seen of the 225 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February–March and May
In those months about 10% of wildlife watchers report a Grandala in Langtang National Park on a given day, against under 5% in April and June–January, the lowest months. Those are among Langtang National Park's driest months, with about 75 mm of rain a month against 390 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grandala sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Langtang National Park, in our data
Langtang National Park is the only park on Wallace's Line with enough records to rate Grandala sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Muscicapidae
The closest relatives of the Grandala that you can see in Langtang National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Blue Whistling-Thrush (about 70%), Blue-fronted Redstart (about 50%) and Plumbeous Water Redstart (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grandala is recorded against all the birds logged in Langtang National Park (26 verified sightings from 2019 to 2026), 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.
