Cyanolyca nanus
The Dwarf Jay (Cyanolyca nanus) is the smallest of the New World jays, a vibrant jewel of the montane cloud forests. Measuring a modest 20-23 cm in length and weighing approximately 40-60 grams, it presents a striking appearance with a velvety black head, throat, and upper chest, contrasting sharply with its brilliant, deep blue body, wings, and tail. A distinctive small white patch, resembling a 'moustache,' at the base of the lower mandible and a subtle white orbital ring serve as key ident...
Found exclusively in humid montane evergreen and pine-oak cloud forests, preferring areas with dense understory and abundant epiphytes. Inhabits elevations typically ranging from 1,200 to 3,050 meters above sea level.
Primarily insectivorous, feeding on beetles, caterpillars, and other arthropods gleaned from vegetation. Supplement their diet with small fruits, berries, and occasionally small vertebrates like lizards or eggs.

They primarily forage by gleaning insects and larvae from bark, mosses, bromeliads, and foliage within the mid-to-upper canopy, occasionally sallying to catch flyi...
The Dwarf Jay is a resident species, endemic to the humid montane cloud forests of southern Mexico and western Guatemala, with a disjunct distribution.
