Food Habits - Diet
Ord's Kangaroo Rat are PRIMARILY Herbivores. However, they do eat nuts, insects and grains, as well as forbs, so have become adapted as Omnivores. Also, since they mainly eat grain they can be called Grainivourous
They only drink water if it is absolutely necessary.
They store food underground for later use, and the have large cheek pouches to carry food
Predators
The main predators for the kangaroo rat are;
Owls - Great Horned and burrowing owls
Foxes
Coyotes
Badgers
Moles
Long-Tailed weasels
Rattle Snakes
The Ord's kangaroo rat stay in burrows during the day, and on clear nights in order to avoid predators from seeing them. Therefore, they are most active on cloudy nights, due to the cover and protection that a clear night would not offer.

In What Ways Would the
Extinction of Kangaroo Rats
Affect the Food Web?
Although they are omnivores, they consume mainly plants. Therefore, they are considered primary consumers. So, if there are less primary consumers to convert energy from the producers, the less energy will be available to the secondary consumers and decomposers.

What are the Main Factors Threatening Ord's Kangaroo Rat?
The main actor threatening the existence of the kangaroo rats is humans. Why? Since the rats eat mainly grains and seeds, farmers view them as pests and a threat to the crops. So, they use pesticides to exterminate the rats from the area, causing loss of habitat.
Hypothesis
If Ord's Kangaroo Rats become extinct, then, not only will it affect the food chain that they are a part of, but it will create an unbalance in populations of other species in the general area, resulting in altered food chains for those species as well.
Habitat
Temperate and 'Terrestrial' Biomes:
Terrestrial -
Deserts/Dune or Savanna and Grasslands
Agricultural
Kangaroo Rats
ENDANGERED
since 2006
Interesting Facts
Unlike most rats, this type o f kangaroo rat does not carry diseases
Kangaroo rats can jump up to 9 ft high
The have the ability to convert seeds which they store in fur-lined cheek pouches, into water
They don't sweat - A way to conserve water loss
Life expectancy is 2-5 years, but in Canada, most won't even survive 1 year
Species Protection
and Survival
Scientists say the only way to rescue population decreases is human intervention. They are trying to prevent extirpation from Canada by relocating 10-20 individuals every spring, without harming the population to observe whether or not they can establish themselves in a new location

What is Currently Being Done
Nature Canada held public hearings about plans to expand gas and well drilling inside of Alberta's Suffield National Wildlife Area. The area contains burrowing owls and the ord's kangaroo rat, which are both endangered. They mounted a strong case, which imposed strict conditions for companies etc. to get a drilling permit.
Kangaroo rats are currently under protection under the Provincial Wildlife Act, as well as the federal Species at Risk Act (SARA) and in Saskatchewan, the Wildlife Habitat Protection Act protects the habitats by prohibiting clearing and fragmentation of Crown Islands - Prohibits agricultural and industrial development.
