Yellow-green grosbeak

In 1760 the French zoologist Mathurin Jacques Brisson included a description of the yellow-green grosbeak in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le Gros-bec de Cayenne and the Latin name Coccothraustes Cayanensis.[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.[3] 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.[3] One of these was the yellow-green grosbeak. Linnaeus included a terse description, used the binomial name Loxia canadensis and cited Brisson's work.[4] Linnaeus mistakenly claimed that the species occurred in Canada rather than Cayenne and introduced the specific name canadensis for Canada where the bird does not occur.[5] This species is now placed in the genus Caryothraustes that was introduced by the German naturalist Ludwig Reichenbach in 1850.[6] There are four subspecies.[7]

It is found in Brazil, Colombia, French Guiana, Guyana, Panama, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.
