An extraordinary animal left us last week. Boomer siamang, father of Leela and mate to Jambi, lost his battle with a chronic illness that had plagued him for years. Our veterinarians and keepers battled right along with him, keeping him feeling good with many treatments and medications and consulting with human gastroenterologists and other veterinarians at every twist and turn throughout his illness. In the end, all of it was just too much for him, and at the age of 25, he passed quietly surrounded by the keepers who loved him as their tears fell.
Boomer was a very special guy. He resided at the Houston Zoo since he was a 3 year old, and showed us right away that he was unique. He had an innate sweetness, and told his keepers right away if they were to his liking….or not. Even his favorite keepers had to use caution around him: he had a powerful grab at the end of those long gibbon arms, and many staff members were surprised as they had their hair pulled by him in a sneak attack. Like most primates he always let us know that would not tolerate us thinking of him as anything but the wild animal that he was.
Conversely, his gentle side was frequently evident. As a father he was devoted to his offspring. He fathered three kids and doted on them. The first, “Jacoma”, was born via Cesarean section and had to be hand-reared, but he came into his full parental role with his next two. Most siamang males help to carry their babies when the little ones are about 8 months old. Boomer started carrying his last two youngsters “Raya” and “Leela” when they were 8 weeks old. He allowed Leela to crawl all over him, even when he was not feeling his best. She would wander up to him playfully and curiously grab his deflated throat sac or traipse over him as he lay in the sun as if he were her personal doormat. He had such patience with his babies. And, he was a fiercely protective father: anyone who came up to his exhibit to see the latest new baby was left with no doubt that he was in charge and would defend her to the end.
Once he accepted someone, and he had legions of staff members over the years whom he did accept, he would allow them the high privilege of turning to present his back for grooming. Boomer loved a good backscratch, and he received many in his lifetime. He’d press his back against the mesh wall and relax as his keepers would knead his muscles and groom the thick black hair on his shoulders. One had to do this carefully, for the ever-present danger of being grabbed was always there, but Boomer would allow this the way a king accepts gifts from his subjects.
Siamangs sing together to bond with their mate and to defend their territory. One of the joys of the primate staff and volunteers was to listen to them sing together: their astonishing duet was heard all over the zoo and even over at the medical center. Guests were mesmerized as they watched the pair blow up their throat sacs and vocalize at an ear-shattering decibel level. One truly had the sense of their magnificence as their intricately matched song resonated; a sound that you could feel thrumming in your bones as they called. We will miss Boomer’s song. We will miss his wise face watching over his family. We will miss seeing him soaking up the sun on beautiful mornings.
We will miss our boy Boomer.

Beautifully written tribute to a much loved member of the WWP family.
im very sorry for your loss……bu reading this great article i learned that Boomer was a very unique and wonderful animal…..very happy to see that you all take very much pride in caring your animals….i was never lucky to hear those songs that u speek of, i wish i had herd…again sorry for your loss…..bye Boomer
Such a loss.
Sounds are a big thing at Houston Zoo: The ocassional trumpet of an elephant; Jonathan, the lion, roaring; the squawking of the macaws; the barking of the sea lions; the high-pitched calls of the Golden lion tamarins; the calls of the red-crowned cranes; the hoots, screams and cries of the chimpanzees. But, the most beautiful sounds are the song of the siamangs.
Siamangs Boomer and Mugget, his then-exhibit mate, were my second-favorite animals (after rhinos) in my docent training and career. I knew when they began singing they would draw a crowd and crowds are what docents do best. Besides, guests NEEDED to know that the siamangs weren’t just making noise for no reason; they were bonding AND announcing territory. It was also the perfect time to watch and appreciate their power and agility as they animatedly moved through the trees and exhibit propping at the high points of their song.
When Mugget died in 1999, Boomer kept up his portion of the song they had sung for so many years. When his new mate, Jambi, arrived a year later she followed Boomer around as he vocalized and she slowly started contributing her side of the song until it was ‘their’ song.
Over time, I got to feel like Boomer recognized me–which I like to think he did. Most of the time while I was interpreting on the viewing platform at their exhibit, Boomer would come over and ‘hang’ on the mesh nearby. Other times, when I was the only person on the platform, he’d just come over and ‘hang’. Even when I just stopped on the ramp to watch them for a minute or two, he’d sometimes come over and just sit on the low concrete wall nearby holding on to the mesh above.
I know I and just about anyone who has seen him will miss him.
RIP, Boomer!
What a lovely tribute, Dale. I know he DID recognize you, and I so appreciate all that you have done to teach people about siamangs for all these years.
(I still miss Mugget, too…)
Thank you Dale, for those words. I don’t know if Jambi will keep up the song without him. I think the frequency of her calling is less now, perhaps because he was often the one to start it. But over the last week, she has sung without him a couple times. There is still Susie (gibbon) to impress, after all!
I am in tears..
RIP Boomer… We will miss you!
This is one of the most beautifully written tributes that I have ever read. May we all be deserving of such a heartfelt tribute.
I was so lucky to get to know Boomer when I did! He was an amazing “person” and I will always remember him! I’m actually happy I was one of those keepers that had their hair pulled out! LOL! It gives me a funny memory to think of now! Love you Boom Boom!
Lynn and other friends of Boomer – what a wonderful tribute to a very special animal! I share your pain at his loss, but believe he is singing again with Mugget in another rainforest where life is perfect again. After decades in this business, I wish I could tell you that losing a friend like this gets easier, but it doesn’t. The grieving you are doing now is a small price to pay for the many wonderful days you’ve had with Boomer and his family. Remember the happy times! I will think of you often in the days to come, and hope that Jambi finds someone to duet with soon!
I am so sorry for the lose of such a wonderful being! I remember the first time I saw Boomer sing! He made my heart so happy! He will be in my heart forever!
