The Unicolored Jays (Aphelocoma unicolor) are dark-blue jays found in the wet cloud forests of Central America and Mexico.
Their range stretches from the Mexican states of San Luis Potosí (north-central Mexico) south to Veracruz (Eastern Mexico) and Guerrero (Southwestern Mexico) to west-central Honduras and El Salvador.
They are most common at elevations from about 7,000 – 10,000 feet (~2,100 and 3,050 meters).
