The azure-hooded jay (''Cyanolyca cucullata'') is a species of bird in the family Corvidae. It is found in Middle America. Its natural habitat is subtropical or tropical moist montane forest. This species is known to have four subspecies. It is in length and is dark blue with a black head and upper chest. The back of the head and neck are sky blue with a white border. The jays travel in groups of two to ten individuals and may join mixed-species flocks. It is a secretive species and therefore difficult to observe in the wild. As an omnivore, this jay eats berries, seeds, and small, dead animals. Females lay three to four eggs, and the young fledge after twenty days. This species is listed as Least Concern, meaning it is not threatened with extinction. ==Taxonomy== The species was first described by the American ornithologist Robert Ridgway in 1885. Its specific epithet, ''cucullata'', is the Latin word for "hooded". Its closest relative is the beautiful jay (''C. pulchra'') of Colombia and Ecuador;〔Goodwin, p. 258〕 in his 1934 study, Hellmayr treated these species as conspecific. Phylogenetic analysis published in 2009 confirmed the close relationship between the two species; Bonaccorso speculates that the geographic (and subsequent genetic) separation between these species and others in the ''Cyanolyca'' genus may have been initiated by the formation of the Río Cauca Valley in western Colombia. The azure-hooded jay has four subspecies. ''Cyanolyca cucullata mitrata'' is found in eastern Mexico, from San Luis Potosí to north central Oaxaca. This subspecies was initially treated as a separate species by Ridgway, but it was later merged into the azure-hooded jay.〔 ''C. c. guatemalae'' ranges from southern Mexico in Chiapas to central Guatemala.〔 ''C. c. hondurensis'' resides in western Honduras.〔 ''C. c. cucullata'', the nominate subspecies, is found in Costa Rica and western Panama.〔
