The white-tailed jay (Cyanocorax mystacalis), also known as the moustached jay, is a species of bird in the crow family Corvidae. It is found in Ecuador and Peru. It has a black face with white spots above and below the eyes, and a small white moustachial stripe. It has a white nape, belly, and underparts. Its back and wings are greyish-blue, extending most of the way down the tail. The rectrices and tail tip are white. It has several calls, the most common being described as "cha-cha-cha-cha". The white-tailed jay was first described by the French ornithologist Louis Ernest Gustave de Sparre in 1835 and was given the scientific name Pica mystacalis. It was later placed in the genus Cyanocorax. It is visually very similar to the tufted jay, which is found in Mexico over 4,800 km (3,000 mi) away, and the two species were incorrectly thought to be close relatives. The white-tailed jay's relationship to others in the genus Cyanocorax is still unclear.
