Columbia Basin Pygmy Rabbits are the world's smallest and among the rarest. Native only to a single area of Washington State, this once isolated population of Pygmy rabbits usually weighs less than a pound in adulthood and was declared extinct in the wild in the '90s, after the remaining 14 bunnies were scooped up and taken into the equivalent of bunny protective custody.
This year the Oregon Zoo welcomed 26 of the little guys, bringing this year's total to 73 baby bunnies (kits) among participating breeding facilities. Color is added to the ears in the pictures below so zoo staff can tell the kits apart.
Unlike most rabbits, the Columbia Basin Pygmy Rabbit did not breed prodigously in captivity, partially due to inbreeding within the tiny wild population. As a result they were cross bred with Idaho Pygmy Rabbits and subsequent breeding efforts have been more successful.
