At this time we rejoice essentially the most endangered apes on this planet: orangutans! The Jungle Trails staff cares for one particular Sumatran orangutan right here on the Cincinnati Zoo & Botanical Backyard, Henry! Orangutans are thought-about semi-solitary apes so that they spend extra time alone than with others. Whereas Henry has had feminine orangutan companions up to now, he has proven a choice to a bachelor life-style which we respect. Henry can typically be discovered “hanging” round along with his gibbon associates Lance and Hosen.

Labeled as critically endangered, Sumatran orangutans are certainly one of 2 subspecies of orangutan (the opposite being Bornean). Orangutans are the one non-human nice apes discovered outdoors of Africa and dwell in Indonesian and Malaysian rainforests.

Shut Sufficient to Care:

The zoo has a mission of getting visitors “shut sufficient to care” which is vital for not solely our visitor expertise but additionally our conservation efforts. For our workers and animals, nevertheless, this objective takes on a complete totally different that means. Jungle Trails keeper Stephanie talks about how we use shut relationships, and optimistic reinforcement, to handle Henry:

Monitoring coronary heart well being is a vital part of caring for the apes on the Cincinnati Zoo & Botanical Backyard.  We started conditioning Henry, together with the bonobos and gorillas, to obtain an awake echocardiogram, an ultrasound of the guts, in 2011.  In doing this, we might have the flexibility to take a look at how the guts is functioning with out having to have the animal below anesthesia.

There are a lot of steps that lead as much as this – constructing a relationship with Henry by optimistic rewards, discovering what meals inspire him essentially the most, and introducing the entire gear wanted to carry out the ultrasound.  We started with a pretend ultrasound probe made with a PVC pipe with an finish cap on it, simply so he would get conversant in the feeling of it urgent on his chest.  When he was snug with that we began so as to add a little bit little bit of ultrasound gel, which is critical for the photographs to return by.  Henry has by no means been a fan of the gel, however will endure it for some grapes and yogurt!   After this step, we launched a small ultrasound machine, simply robust sufficient to see the guts to know the place the right spot was on Henry to get the photographs of his coronary heart.  The ultimate step was to usher in the big ultrasound machine and likewise get Henry used to seeing our volunteer technician, Jenny Schaaf, who would run the machine and talk to me which option to flip the probe to get all the photographs she wanted. Henry fortunately was not phased by the machine in any respect and did very nicely with seeing a brand new face!

In addition to Henry did, male orangutans are extraordinarily troublesome to get nice photographs on.  They’ve a big air sac that drapes over their chest and likewise a outstanding rib cage.  Since Henry’s coronary heart was wholesome at the moment, he solely acquired an ultrasound throughout his common checkups whereas below anesthesia.  Throughout his final checkup although, it was discovered that he had the beginning of some heart problems.  With this prognosis, we determined to begin up the awake echocardiograms and make some modifications to assist with the problems we had up to now.  Our upkeep staff has constructed a “coronary heart field” that matches over the port we use for Henry’s blood strain sleeve.  It’s going to permit Henry to face able the place his air sac can lay on high of this metal mesh field and his chest will be nearer and extra accessible for the ultrasound probe to seize the photographs wanted.  Henry is doing nice along with his conditioning, he picked proper again up the place we left off like a professional!

Together with echocardiograms, blood strain is one other vital issue of coronary heart well being that may inform us loads about how our our bodies are functioning.  Henry’s blood strain coaching began in 2018.  Just like the ultrasounds, there have been a fantastic many steps that led as much as attaining this habits.  Designing the metal mesh sleeve that Henry would place his arm into, discovering the suitable measurement cuff, getting Henry used to the entire shifting elements and likewise used to the feeling of the cuff squeezing his arm.  His main trainers labored diligently to make this course of a hit and Henry’s first readings had been recorded in March of 2019!  Some modifications wanted to be made to verify the readings had been correct, and now Henry voluntarily has his blood strain monitored a number of occasions a month, so long as there’s pineapple concerned!”

The Cincinnati Zoo & Botanical Backyard, and the Affiliation of Zoos & Aquariums, are each taking motion to assist orangutans, and you’ll too! Right here’s how one can assist:
