Description

The Hellstern's Sylph is mainly shiny green in colour. The upperparts range from light green to greenish-blue while the underparts are dark green. The crown is mainly blue to indigo. The tail is indigo to purple. Wings are bluish-green. Feet and bill are black and eyes are dark. Female is similar, but with a shorter tail.

The green, blue and purple are not pigments, but rather it's caused by iridescence, which are structural rather than chemical in nature, and is caused by interference.[2]
