Indochinese green magpie, also known as the yellow-breasted magpie 
(Gẻ cùi bụng vàng, Cissa hypoleuca)

The Indochinese green magpie is a small colorful bird native to the forests of China and Vietnam.
While most Cissa species have the lower body green, those in Vietnam and in southern Southeast Asia have the lower body yellow.

The name Cissa is from the Ancient Greek kissa meaning a "jay" or "magpie".
hypoleuca: from two Greek roots: hupo, "below", and leukos, "white".
