So, what is the smallest ʀᴀʙʙɪᴛ in the world?
The Columbia Basin Pygmy Rᴀʙʙɪᴛs is one of the smallest ʀᴀʙʙɪᴛ species in North America, and perhaps, the smallest ʀᴀʙʙɪᴛ in the world. They typically weigh under a pound, making them less than half the weight of your average cottontail (which weighs in at an average of 2.5 pounds).
Columbia Basin Pygmy Rᴀʙʙɪᴛs are the world’s smallest and among the rarest. Native only to a single area of Washington State, this once isolated population of Pygmy ʀᴀʙʙɪᴛs usually weighs less than a pound in adulthood and was declared ᴇxᴛɪɴᴄᴛ in the wild in the ’90s, after the ʀᴇᴍᴀɪɴing 14 bunnies were scooped up and taᴋᴇɴ into the equivalent of bunny protective custody.
This ʀᴀʙʙɪᴛ has a distinctive appearance and behavior. If you were to spot one, you would probably know it – and not just beᴄᴀᴜsᴇ they are the smallest ʀᴀʙʙɪᴛ in the world. Columbia Basin Pygmy Rᴀʙʙɪᴛs also have shorter ears, and shorter legs, compared to your average cottontail.
These ʀᴀʙʙɪᴛs lack your typical ʙʀᴇᴇᴅ’s white fuzz, as well. They are brown to dark gray all over. Their fur tends to lighten as the seasons move toward winter.
The Columbia Basin Pygmy Rᴀʙʙɪᴛ is always active, but especially during the twilight hours just before dawn and dusk. This is when these ʀᴀʙʙɪᴛs feel they have the most cover.
The smallest ʀᴀʙʙɪᴛ in the world acts much like your average ʀᴀʙʙɪᴛ does, spending its time grazing, ʙʀᴇᴇᴅing, pʟᴀʏɪɴɢ, grooming… and evading the frequent ᴘʀᴇᴅᴀᴛᴏʀ.
Unlike most ʀᴀʙʙɪᴛs, the Columbia Basin Pygmy Rᴀʙʙɪᴛ did not ʙʀᴇᴇᴅ prodigously in ᴄᴀᴘᴛɪᴠɪᴛʏ, partially due to inʙʀᴇᴇᴅing within the tiny wild population. As a result they were cross ʙʀᴇᴅ with Idaho Pygmy Rᴀʙʙɪᴛs and subsequent ʙʀᴇᴇᴅing efforts have been more successful.
As a matter of fact, Columbia Basin Pygmy Rᴀʙʙɪᴛs have come to depend on this highly unique haʙɪᴛat for their survival. The hills and slopes between plateaus and riverbeds serve as the perfect spots to burrow.
There are sagebrushes for the Columbia Basin Pygmy Rᴀʙʙɪᴛs to feed on – everywhere!
Sᴀᴅʟʏ, their reliance on this special environment and its decimation by wildfɪʀᴇs has left the Columbia Basin Pygmy Rᴀʙʙɪᴛs ʙʀᴇᴇᴅ seriously at ʀɪsᴋ.
