"[2] In 1760 the French zoologist Mathurin Jacques Brisson included a description of the balicassiao in his Ornithologie based on a specimen collected in the Philippines.

[3] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.

[4] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson.

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

Nest found in March was described as an open cup made of brown plant fibers and cobwebs.

The IUCN Red List has assessed this bird as least-concern species as it is still locally common and has a large range despite deforestation in the Philippines[10]
