The Madagascar blue vanga (Cyanolanius madagascarinus) is a bird species in the family Vangidae. It is found in Madagascar, where its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the blue vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name Le pie-griesche bleu de Madagascar and the Latin name Lanius Madagascariensis coeruleus. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition in 1766, he added 240 species that had been previously described by Brisson. One of these was the blue vanga. Linnaeus included a brief description, coined the binomial name Loxia madagascarina and cited Brisson's work. The species is now placed in the genus Cyanolanius that was introduced by the French naturalist Charles Lucien Bonaparte in 1854.

Possible
About 30% of wildlife watchers report a Blue Vanga sighting in Mantadia National Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 98 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 60% of wildlife watchers report a Blue Vanga in Mantadia National Park on a given day, against about 20% in June and October–December, the lowest months. That is one of Mantadia National Park's driest months, with about 80 mm of rain against 340 mm in January. January to April have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Blue Vanga sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Blue Vanga sightings, Mantadia National Park ranks 3rd at about 30%. The best odds are in Ranomafana National Park (Madagascar, about 40%) and Ankarafantsika National Park (Madagascar, about 30%).
Same family: Vangidae
The closest relatives of the Blue Vanga that you can see in Mantadia National Park (family Vangidae, Vangas, Helmetshrikes, and Allies) are Red-tailed Vanga (about 50%), Common Newtonia (about 50%) and Nuthatch-Vanga (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Vanga is recorded against all the birds logged in Mantadia National Park (151 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.
