Based on a model of future deforestation it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.

Cyanolyca viridicyana Sibley and Monroe (1990, 1993), Cyanolyca viridicyana Stotz et al. (1996)
34cm, 82-127g. Almost completely cerulean blue, with forehead, lores and ear coverts black and the throat and upper breast dark blue. The forecrown is white and this extends around the upper edge of ear coverts and edge of face to connect with a thin white border which divides the throat and upper breast. Subspecies C. v. cyanolaema is dark blue on the throat and C. v. jolyaea is more purplish blue and has the greatest contrast between the throat and the black ear coverts. Similar spp. Turquoise Jay C. turcosa has a black border dividing the throat from the breast, the throat is also more blue than C. viridicyanus. Voice Complex and variable, with many variations and almost endless combinations. A frequently cited phrase is a rapid staccato chatter likened to a tinny machine-gun, also a mellow piped and repeated "wau".
Conservation Actions Underway
None is known.
Conservation Actions ProposedExpand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).
