The Madagascar blue vanga (Cyanolanius madagascarinus) is a bird species in the family Vangidae.

[1] 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.

[2] 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.

Linnaeus included a brief description, coined the binomial name Loxia madagascarina and cited Brisson's work.

[4] The species is now placed in the genus Cyanolanius that was introduced by the French naturalist Charles Lucien Bonaparte in 1854.

Race comorensis has similar calls, but also makes a grating erch-chhh-crkk-chh-chhh-chhh-crrk or a harsher crew-crew-crew.

Eggs are pale blue to green and have mid-sized lilac-gray to red-brown speckles, which are the densest at the larger end.

[6] The nominate race on Madagascar faces few threats due to its large range and population.
