Black footed ferret kits TorontoZooToronto Zoo has been par­tic­i­pat­ing in the con­ser­va­tion breed­ing pro­gramme for the black-​footed fer­rets since 1992. Since then, the Zoo has bred hun­dreds of baby fer­rets (kits) for rein­tro­duc­tion to the wild in USA, Mex­ico, and Canada where they were listed as extir­pated in 1978. This pro­gramme is sig­nif­i­cant as Toronto Zoo re-​established an extir­pated, North Amer­i­can species back into the prairies.

The black-​footed fer­ret was once thought to be extinct in the wild.

Sav­ing species at risk like the black-​footed fer­ret is only pos­si­ble through part­ner col­lab­o­ra­tion and the suc­cess of inter­na­tional fer­ret recov­ery demon­strates how work­ing together can have a big impact on sav­ing crit­i­cally endan­gered species,” says Franke.

The black-​footed fer­ret
The black-​footed fer­ret (Mustela nigripes) is listed as Endan­gered accord­ing the IUCN Red List of Threat­ened Species™. The US Fish and Wildlife Ser­vice devel­oped and over­sees the Black-​Footed Fer­ret Recov­ery Pro­gram. The Asso­ci­a­tion of Zoos and Aquar­i­ums’ Species Sur­vival Plan man­ages the black-​footed fer­ret breed­ing pro­gramme at ex situ facil­i­ties, such as zoos and breed­ing cen­tres, with a breed­ing pop­u­la­tion com­posed of about 300 animals.

This year, Toronto Zoo has 16 adult fer­rets. One female, named Twi­light Sparkle after a My Lit­tle Pony char­ac­ter, gave birth to four kits (three males and one female) on 16 April 2016. Kits are born blind, hair­less, and are less than 10 cen­time­tres long. Twi­light Sparkle was instantly a very good first-​time mother, nurs­ing and pro­tect­ing her babies. The kits weaned at approx­i­mately 30 days of age and started eat­ing meat brought over by their mother. A week or so after wean­ing, their eyes started to open and they began to explore their sur­round­ings. Now at 73 days old, their per­son­al­i­ties are strong and they are very active and chatty. The kits had their first vet­eri­nary check-​up last week and are all healthy with beau­ti­ful adult colours. They are full grown and the boys already weigh more than their mother, adult females weigh 700800 grams and adult males 9001,000 grams.

On 13 June, another female named Indigo gave birth to six kits, though two appeared to have been still­born. Six kits would have been a large lit­ter size, espe­cially for Indigo being a first time mum. Mother and kits have been doing very well so far.

Four other females bred this year; three did not become preg­nant. The remain­ing female, named Fid­dle­sticks, gave birth on 22 June to one kit. Females can have between one and seven kits, with an aver­age lit­ter of three to four, so this is a small lit­ter but not uncom­mon. Fid­dle­sticks is an expe­ri­enced mother and not both­ered by a sin­gle noise in the barn.

In the fall, kits will go to the National Black-​footed Fer­ret Con­ser­va­tion Cen­ter in Col­orado to pre­pare for release into the wild. They will live in out­door pens and learn valu­able skills such as hunt­ing prairie dogs.

Appar­ently Toronto Zoo is con­tribut­ing sub­stan­tially to the con­ser­va­tion breed­ing pro­gramme for the black-​footed fer­rets, which has helped restore the wild pop­u­la­tion to approx­i­mately 300 ani­mals. How­ever, due to habi­tat loss and dis­ease the still small pop­u­la­tion of this fer­ret species in the wild con­tin­ues to need support.
