Xindi-Avian

The Xindi-Avians are an extinct species of sapient volant lifeforms and were the sixth sapient race native to the planet Xindus. The skull of this species appears almost identical to that of an Earth giraffe.

History
History says the Avians once darkened the skies with their numbers, but their technology wasn't as advanced as that of the other five Xindi races. Unlike the others, the Avians were not able to evacuate the planet by the time of its destruction.
