Denver Zoo uses ‘blood siphons’ to cool animals during summer heat

DENVER (KDVR) – As temperatures slowly creep toward triple digits, Colorado residents are looking for ways to cool off in the summer heat. But some Denverites need more than just air conditioning and water.

The Denver Zoo Conservation Alliance told Nexstar’s KDVR that it provides cool indoor spaces for every animal, but not every animal wants to stay inside.


“There are air-conditioned indoor areas available to cool off, but it’s no surprise that our wildlife Doing “They want to be outside, and that’s what we want for them,” the zoo said.

To keep the animals cool during the historically hottest summer days, zookeepers are taking creative measures to keep the animals cool.

Zoo uses strange methods to cool animals

For some animals, zoo specialists use fans, misters and ice machines during the hot weather. Meanwhile, other animals use strange and expensive methods to stay cool.

For the Amur tigers, which naturally live in Siberia, the specialists make meat and blood ice creams, or “blood ice creams” if you want to call them that, according to the zoo.

While not exactly palatable to humans, the zoo says the big cats love it, especially because the ice creams provide mental stimulation.

The zoo’s spotted hyenas like to cool off in hot tubs.

“Hot tubs also serve as enrichment, as hyenas like to hide things in water and return to them later. Our Animal Care staff hide fun items for the pack to find and increase the challenge level by making the items difficult to see,” the zoo said.

Other animals only need shade, but that shade comes at a price.

For some zoo habitats, animals need more shade solutions than just tree cover. For flamingos, the zoo uses a modified shade sail.

Adding in the concrete caissons, steel for the posts, shade material and installation, the zoo says it comes to $65,000 each.

While the animals prefer to be outside, the specialists do everything they can to ensure that the animals are comfortable during the hottest days of the year.
