White-collared Jay Cyanolyca viridicyanus
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information


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.

Taxonomic note
Gender agreement of species name follows David and Gosselin (2002a).

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".

Distribution and population
C. v. viridicyanus occurs in NW Bolivia, C. v. cyanolaema in SE Peru (Cuzco and Puno) and C. v. jolyaea in N and C Peru (from Junin to Amazonas).

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend justification
This species is suspected to lose 29.4-30.1% of suitable habitat within its distribution over three generations (20 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by a rate approaching 30% over three generations.

Montane forest up to stunted elfin forest between 1600m and 4000m, though primarily up to 3000m. Also recorded in secondary growth where bamboo and tree-ferns are abundant. Forages in the canopy and subcanopy, investigating epiphytes and leaf clusters along branches.
Sedentary, breeding undocumented, though video of pair nest-building shows an medium sized open cup nest made primarily of small branches at mid-level.

Projected deforestation is the primary threat affecting this species (Soares-Filho et al. 2006, Bird et al. 2011).

Conservation Actions Underway
None is known.

Conservation Actions Proposed

Expand 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).
