Kenya: A conservation group in Kenya shared video of two ultra-rare giraffes with white coloration caused by a genetic abnormality.

The Hirola Conservation Program posted a video to YouTube showing the two white giraffes, a mother and a baby, walking among some trees, reports UPI.

The group said the video was filmed by rangers in northeastern Kenya.

The giraffes’ coloration is believed to be the result of a genetic conditioncalled leucism, which differs from albinism in that it results in only a partial loss of pigmentation.

White giraffes were first reported in January 2016 in Tanzania’s Tarangire National Park. The only confirmed sightings thus far have been in Tanzania and Kenya.
