Color Spray (Su): Once per round, a corollax can unleash a vivid cone of clashing colors. This ability works like a color spray spell (caster level 1st; save DC 13). The creature is immune to its own color spray attack and to those of others of its kind.

Corollaxes are not aggressive and do not attack unless someone attacks or harasses them first. If disturbed, a corollax screeches and flies about, unleashing its color spray attack. If forced into melee, the bird combines both claws into a single attack.
