Black-footed ferrets are fast and inquisitive animals. They have an excellent sense of smell, sight, and hearing, and the ability to climb. Ferrets defend themselves by using their sharp, non-retractable claws and strong jaws.
Black-footed ferrets have a specialized diet and environment. Their unique lifestyle made them almost extinct in the wild by the 1970s due to habitat destruction and a food shortage.
Besides, during the mating season, black-footed ferrets live a solitary life. Males are territorial, and they will fight other males for their territory. So what do black-footed ferrets eat to live? Let’s take a look below.
What Do Black-Footed Ferrets Eat To Survive?
Carnivorous black-footed ferrets are genetically disposed to hunt and eat the species such as prairie dogs. The Prairie dog is essential to the ferret for more than just food.
According to a US Geologic survey published in 2008, the ferrets use the Prairie dog’s burrow for their own refuge. This establishes a strong bond between the black-footed ferret and the prairie dogs. The cause for the quick decline in ferrets’ population has largely been linked to the prairie dog’s population decline.
One adult female black-footed ferret and her children require around 480 to 1,399 black-tailed prairie dogs per year or 405 to 1,246 white-tailed prairie dogs per year.
Once they reach adulthood, young ferrets will migrate to different places to eat. They usually look for prairie dogs when hunting, implying that the dogs are one of their primary food sources.
Because of this nutritional need, environmental preservation for black-tailed and white-tailed prairie dogs is critical.
92 to 236 acres must be preserved for black-tailed prairie dogs, whereas 414 to 878 acres must be protected for white-tailed prairie dogs. These figures are for each female black-footed ferret with a litter.
What Foods Do Black-Footed Ferrets Eat?
Black-footed ferrets require prairie dogs as their primary food source. In the past, prairie dog populations usually fall when the grasslands became populated, owing to human eradication and habitat alteration due to urbanization and agricultural activities.
The disappearance of the black-footed ferret in Canada was attributed to these reasons.
How Do Black-Footed Survive On Their Diet?
Black-footed ferrets mainly look for food in prairie dog burrows; otherwise, they resort to the insects or rodents found underground or at night.
When threatened, black-footed ferrets have anal glands that produce a powerful unpleasant odor known as the musk. These anal glands are also used to mark territory and food stockpiles, as well as to attract mates.
What Do Black-Footed Ferrets Eat If They Can’t Find Prairie Dogs?
Prairie dogs make up 90% of the ferret’s food. Therefore they’re specialized predators. With their fangs and powerful jaws, they’re designed to hunting prairie dogs. Prairie dogs are generally larger than ferrets. Thus ferrets will often chase them when they are asleep.
If black-footed ferrets cannot find any prairie dogs, they will resort to eating other animals to survive. These include the following:
Black-footed ferrets eat ground squirrels since they are usually found in burrows or on the grounds. The ground squirrels dig and build their burrows in areas that are not wet and those with the higher ground near the burrow.
The burrows of prairie dogs are also often made in such locations, which is why black-footed ferrets may hunt and eat ground squirrels even when there are prairie dogs nearby.
Squirrels are harder for black-footed ferrets to hunt since they generally live on trees. Ground squirrels are genetically related to prairie dogs, making the animal a good substitute for the black-footed ferret’s diet when it cannot find them.
Ground squirrels are found in many of the continents worldwide, except in the Antarctic and Australian regions. Their preference to live in fields, green areas, and wooden areas makes them an easy target for black-footed ferrets.
Ground squirrels also make for a good hunt for the black-footed ferret since they are smaller and easy to digest.
The short limbs and long tails of most rodents make them a good snack for black-footed ferrets. Rodents have a diverse ecology and are found in the majority of terrestrial habitats around the world.
They have become a part of the black-footed ferrets’ diet due to their high population and small size.
Small rodents are easy to hunt for black-footed ferrets. The rodents usually hide in the grasslands and burrows, making it easier for the ferrets to hunt and kill them.
The cottontail rabbit is a commonly seen species in North America, Central America, Northern America, and Central South America. The animal is usually seen in nests as well as on the ground. They are hunted by many animals, including black-footed ferrets.
Cottontail rabbits are a good replacement for a primary food source for black-footed ferrets, especially when they face a shortage in finding prairie dogs or other animals.
The importance of the cottontail rabbit in animals’ diets is significant in how it is the main source of food for wolves.
Cottontail rabbits can be born in an average of three litters per year, and the newborn babies are vulnerable to attacks from predators, which means that only a few of the children make it to adulthood.
With more than 10,000 species around the world, there are a multitude of birds for black-footed ferrets to choose from for their diet. A black-footed ferret may eat a bird or even its’ eggs. This is possible for the ferret, even if the birds nest is on a tree, as they can climb trees if necessary.
Since black-footed ferrets live in burrows, they may also hunt birds that travel to the ground to drink water or eat insects.
Black-Footed Ferret Habits Of Eating And Feeding
Ferrets eat prairie dogs exclusively, although they may also eat other animals like ground squirrels (Citellus tridecemlineatus), pocket gophers (Geomys bursarius), deer mice (Peromyscus spp.), cottontail rabbits (Sylvilagus floridanus), upland plovers (Bartramia lingicauda), and horned larks.
However, black-footed ferrets rarely hunt for animals other than prairie dogs. It is likely they only resort to eating other animals when they do not find any prairie dogs.
Prairie dogs, thirteen-lined ground squirrels, cottontail rabbits, mice, and birds, both living and dead, are easily eaten by young ferrets near their burrows.
Young ferrets approach live-tethered prairie dogs with caution, usually sniffing them, and then grabbing them by the side of the neck and dragging them down a burrow. If the ferrets are unable to pull them down the burrow, they would not consume any part of the dog until other animals or people are not within the vicinity.
Adult ferrets usually take the dead prairie dogs that they kill into one burrow, and may even carry them to another burrow later on.
What Do Black-Footed Ferrets Eat? – Conclusion
The black-footed ferret is the only ferret species endemic to North America. They used to live in the United States, Canada, and Mexico’s Great Plains.
They are completely reliant on the black-tailed prairie dog for food and access to their burrows, where they rest and rear their young.
Before European colonization, Prairie dog colonies covered 20% of western rangeland, providing adequate habitat for the black-footed ferret. Despite their extinction, black-footed ferrets are gradually re-emerging into their previous habitats.
