50 years ago, this California sanctuary began saving some of the world’s rarest gibbons, today, their morning songs are a remarkable story of survival
The Gibbon Conservation Center in Santa Clarita Valley marks 50 years of rescuing and breeding some of the world's rarest gibbons. Founded by a self-taught primatologist, the sanctuary now cares for 40 apes across five species and continues its mission under new leadership.
In the hot, dry hills of Southern California's Santa Clarita Valley, north of Los Angeles, the morning air is often filled with a singular sound: the loud, piercing melodies of gibbons. Their calls, ranging from sirens and screeches to low grunts and hoots, reverberate across the sparsely inhabited outskirts and have become emblematic of a sanctuary that has spent five decades fighting for these critically endangered primates.
The Gibbon Conservation Center, as reported by multiple outlets including The Baltimore Sun and The Boston Herald, was founded over 50 years ago and now is home to about 40 gibbons across five species. Known for their signature singing, which happens three to four times a day for 20 to 30 minutes, their vocalizations can sometimes be heard a mile away, a testament to their powerful presence.
A Founder's Legacy
The center began with an unexpected acquisition: Alan Mootnick, a self-taught primatologist who ran a home painting and remodeling business, answered a newspaper ad in 1976 and acquired his first gibbon, Spanky. Over the years, he purchased the 10-acre property in 1980 using money from his business, and he transformed the center into a globally recognized institution dedicated solely to gibbon care and research.
Mootnick, who published scientific papers and welcomed researchers from around the world, became a leading expert on gibbons. According to Director Gabi Skollar, scientists would sometimes send him pictures of rescued gibbons for identification or play him vocalizations. Mootnick passed away in 2011 from heart surgery complications, leaving behind a mission that Skollar was determined to continue.
Continuing the Mission
Skollar, who moved from Hungary to the U.S. in 2005 to learn from Mootnick, initially planned to leave the job to continue her education. But, she said, there was no way to abandon the gibbons: "We have to keep going and take care of this place." Now, she lives on-site with another caretaker, waking each morning to the cacophony of gibbons at sunrise, calling them "her children."
The center's work extends beyond the sanctuary walls. It has successfully bred Javan gibbons for the first time in the world and is sending a pair of northern white-cheeked gibbons to the Pittsburgh Zoo. It also partners with The Teaching Zoo at Moorpark College to give students hands-on experience in animal care, and Skolly is pursuing a doctorate in gibber vocalizations at the University of California, Los Angeles.
Individual Stories
Among the 40 residents, each gorilla has a distinct personality. A young northern white-cheeked gibbon named Pepper leads the chorus, while a pileated gibbon named Violet finishes with her partner, Truman. A rescued gibbon named Pierre reportedly doesn't like men, a quirk that staff take in stride.
Caretaker Jodi Kleier hand-reared a young gibmon named Rocky after his mother abandoned him at birth, and she also prepares meals for the apes, including washed lettuce, steamed sweet potatoes, and bananas. Mara Rodriguez, a development coordinator who first visited the center in the 1990s, has raised four gibbons in her career.
Animal care specialist Sophia offered a cautionary view: "Gibbons are a lot like us humans... No primate should ever be a pet." This reflects the broader threats the species face in the wild, where habitat destruction and the illegal pet trade have sharply reduced populations; some species at the center have fewer than 2,000 left in the wild.
Looking Forward
Skollar's long-term goals include building larger enclosures for the gibbons and constructing an education center for visitors, who are welcome for guided tours on weekends. The center's work includes maintaining genetic diversity through careful breeding and animal exchanges with accredited zoos and conservation facilities.
The story of the Gibbon Conservation Center is one of unexpected beginnings and sustained commitment—from a man who answered a newspaper ad to a sanctuary now recognized across the globe. As the gibbons continue their daily song, their keepers and the scientists who study them are working to ensure that these monkeys' song never fades.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
