The red-billed blue magpie (Urocissa erythroryncha) is a species of bird (magpie) in the crow family, Corvidae. It is about the same size as the Eurasian magpie, but has a much longer tail, one of the longest of any corvid. It is 65–68 cm (25.5–27 in) long and weighs 196–232 g (6.9–8.2 oz).
The red-billed blue magpie was described by French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783, Dutch naturalist Pieter Boddaert coined the binomial name Corvus erythrorynchus in his catalogue of the Planches Enluminées. The specimen described by Buffon had come from China, but the type location was restricted to Canton by Hugh Birckhead in 1937. The red-billed blue magpie is now one of five species placed in the genus Urocissa that was introduced by German ornithologist Jean Cabanis in 1850. The name of the genus... Wikipedia →

Possible
About 20% of wildlife watchers report a Red-billed Blue Magpie sighting in Jim Corbett National Park on a given day, based on 421 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 84th most-seen of the 368 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Red-billed Blue Magpie in Jim Corbett National Park on a given day, against about 10% in February–March, June–August and October–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-billed Blue Magpie sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 5 parks where we can rate Red-billed Blue Magpie sightings, Jim Corbett National Park has the highest daily chance: about 20%. Next come Doi Inthanon National Park (Thailand, about 10%) and Chitwan National Park (Nepal, under 5%).
Same family: Corvidae
The closest relatives of the Red-billed Blue Magpie that you can see in Jim Corbett National Park (family Corvidae, Crows, Jays, and Magpies) are Large-billed Crow (about 40%), Rufous Treepie (about 30%) and Gray Treepie (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-billed Blue Magpie is recorded against all the birds logged in Jim Corbett National Park (421 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.
