Temperatures in the Valley have reached excessive highs as summer season begins — climbing as excessive as 114 levels this previous weekend. That means a change in look after animals at the Phoenix Zoo.
Linda Hardwick, vp of selling, communications and occasions, mentioned that whereas the Phoenix Zoo works to be accountable in selecting animal residents which is able to thrive in the Arizona heat, some do require particular care. In the curiosity of water conservation, the zoo screens its consumption and compares it to that of earlier years.
But staying cool entails greater than water. Keepers at the Phoenix Zoo help their expenses stave off the present heat with inventive options like frozen snacks and water options.
How zoo keepers help animals keep cool
As temperatures hovered round 100 levels on Tuesday morning at the Phoenix Zoo, the animals have been capable of escape the sweltering heat with the help of their keepers.
Indu, the Asian elephant, angled her bulk behind a fence put up, making an attempt to benefit from the meager shade it provided. Her keeper, Ryan Tang, took that as an indication to open the backyard hose, aiming the spray over her head and throughout her face.
She closed her eyes in aid, and commenced siphoning up muddy water from the floor together with her curling trunk to toss over her shoulders, a habits generally known as “claying” wherein elephants cover themselves in mud to create a protecting layer from the solar and bugs.
The 57-year-old has staunch preferences and will not be enticed into the pool she shares with the zoo’s rhino, selecting personal showers as an alternative.
“She’s such a princess,” laughed keeper Madison Temple.

Besides classes with the backyard hose, Indu has entry to an indoor, air-conditioned enclosure and misters on an outside shade structure, in addition to some evolutionary tips up her sleeve. Because the pores and skin on elephant ears is so skinny, Indu can cool herself down by flapping them, dissipating a few of the heat round the blood vessels positioned there.
On significantly scorching days, the zoo’s residents are given frozen treats, and Indu’s was a combination of fruit and her favourite deal with: Gatorade. She will get 15 gallons of the diluted beverage day by day. But, in response to Temple, she retains her caretakers guessing on which taste she needs that day, and flawed selections earn keepers Gatorade to the face.
Reptiles change weight-reduction plan to beat heat
Reptiles, like galapagos tortoise Elvis, cannot eat frozen treats as a result of their internal physique temperature is regulated by their outer situations, keeper Mary Savage mentioned. They’re unable to digest frozen meals and the snacks will get caught of their system for longer, presumably inflicting organ harm.
Instead, they’re given fruit that is excessive in water content material like melons, cucumbers and squash extra continuously in the summer season. Elvis propped himself up on one other tortoise when Savage stood near his facet of the pen.
“The prime tortoise motivation is food,” she joked.
Later, Savage misted Elvis with the hose, for which he stood up on his tiptoes and stretched his neck out eagerly.
Not everybody at the zoo enjoys water, nevertheless. Cheetahs Rhett, Wilkes and Beau choose to hunker down over their blood popsicles — frozen mixtures of water and blood leftover from their meals.
Initially, the three brothers have been unwilling to make the trek down the hill from their spots in the shade. While they’re energetic in the cooler hours of the morning, it is troublesome to influence them to maneuver as soon as the heat units in, Dawn Addelson, the carnivore assortment supervisor mentioned.
“Carnivores spend the majority of their time resting in the shade,” she defined.
Monkeys use cooling pad, misters
The zoo’s ten squirrel monkeys aren’t followers of swimming, both, so their enclosure is about up with a cooling pad and misters on a number of climbing platforms.

The tiny primates swing by way of tall, leafy timber that present ample shade and run alongside connecting ropes hung with ice-encased raisins. Several hung upsides down from the ropes with their ft, making an attempt to free the chained-up ice treats for themselves.
When all else fails, keeper Danyelle Benza mentioned the monkeys could be discovered of their cooled indoor enclosure, spread-eagle on the flooring.
New animals at Phoenix Zoo regulate
For some newcomers to the zoo, the Arizona heat has been an adjustment. Three-year-old Sumatran tiger Raja was transferred in April from Point Defiance Zoo in Tacoma, Washington, and his tolerance threshold is at the moment at 95 levels. That’s when he retreats into his air-conditioned enclosure.
Most zoo animals have entry to their indoor enclosures, referred to as night time homes, as soon as a selected temperature decided by zookeepers primarily based on their species is reached. While Raja is biologically able to withstanding a lot increased temperatures, it is a work in progress. He makes ample use of his personal pool in the meantime.
Wgasa is one other newcomer experiencing Phoenix temperatures for the first time. The Bornean orangutan moved to the Valley from Omaha, Nebraska, in April and thus far will not be a fan of the excessive climate.
The zoo has an outside space for the orangutans, in addition to an air-conditioned day room and underground sleeping areas. Sixteen-year-old Wgasa spends a lot of the day asleep beneath a blanket in the dayroom, and his companion, 17-year-old Rayma, sits in the nook of the dayroom holding a palm frond up in entrance of her.
Keepers present the orangutans with the fronds day by day, and the primates prefer to chew the stalk or use them as cover.
Like reptiles, birds cannot eat frozen meals to maintain their temperatures down, and so should benefit from backyard showers, which keepers present as much as twice a day when the heat climbs above 100 levels.
Archimedes, the Eurasian eagle owl, particularly loves these hose-downs, turning his head beneath the spray and fluffing up his feathers afterward. His ear tufts droop just below the strain, giving him a comically melancholy look.
All birds in the zoo have shaded enclosures and water bowls giant sufficient to take a dip, which Archimedes does typically. Wetting their ft helps them quiet down, as a result of the pores and skin of their ft is uncovered, whereas the remainder of their our bodies is roofed in a thick layer of feathers.
The zoo is at the moment working on summer season hours, from 6 a.m. to 1 p.m., to make sure that guests and animal residents stay cool and cozy. Hardwick recommends that guests carry water and put on mild clothes.
“Be careful, just like anytime you’re heading out into the Arizona sun,” she mentioned.
