Mueller's Gibbon Mueller’s Gibbon Hylobates muelleri A native to Borneo, the Mueller’s Gibbon moves through the trees by swinging from branch to branch. These small apes feed on ripe fruit, and help to disperse seeds throughout the forests. Our Mueller’s Gibbons: Lance (Male): 1/7/1993 Emily (Female): 3/21/1988 White- Handed Gibbon Hylobates lar The white-handed gibbon is a species of ape found throughout South East Asia. Their colors can range from tan, brown, or black in both males and females. Gibbons pairs will often duet in the mornings to communicate with other groups. Our White-Handed Gibbons: Hosen (Male): 5/7/1985 Connie (Female): 8/19/1990 Sumatran Orangutan Pongo abelii Orangutans are a large species of primate found in only two places in the entire world, the islands of Borneo and Sumatra. These beautiful red apes, often shy and elusive, are among some of the smartest animals on the planet! Our Orangutans: Henry (Male): 1/1/1991 Alex (Female): 3/17/1983 Palm Oil and Orangutans In Indonesia, orangutans are losing much of their habitat to the palm oil industry. Huge areas of forest are cleared to make these plantations. Palm oil, processed from the oil palm tree, is an ingredient found in one out of every 10 grocery items. Supporting sustainably sourced palm oil can help protect orangutans and their habitats. DOWNLOAD the Cheyenne Mountain Zoo Sustainable Palm Oil App to help make Orangutan friendly decisions while shopping! Pygmy Slow Loris Nycticebus pygmaeus This slow-moving, nocturnal, prosimian spends most of its time in the trees. When threatened, lorises produce a secretion that becomes toxic when mixed with their saliva, helping to deter predators. Our Lorises: Cai (Female): 12/6/2010 Gilbert (Male): 11/20/2008 White- faced Saki Pithecia pithecia These small monkeys inhabit the tropical forests of Brazil and Venezuela. Known as the “flying monkey,” sakis have the ability to leap 30ft between branches! Male sakis are black in color, with a stark white face and black snout. Different from the males, females are brownish gray in color throughout their whole body. Our White-faced Sakis: Penelope (Female): 7/28/2010 Dakota (Male): 7/11/1992 Golden- headed Lion Tamarin Leontopithecus chrysomelas Known for their beautiful golden manes of hair, Golden-headed Lion Tamarins are a small species of monkeys found only in the coastal forests of Brazil. Unique to other primates, these tamarins live in single female, multi-male groups, where the males play a huge role in infant care. Our Tamarins: Serafina: 12/30/2012 Lucio: 10/22/2005 Lion Tamarin Conservation Success Due to the loss of their native habitats, from urban and agriculture development, Golden Lion Tamarin populations plummeted to as low as 200 in the 1970’s. In the 1980’s, the National Zoo and their partners began a captive breeding and release program. As of 2003, the Golden- Lion Tamarins were downgraded from Critically Endangered to Endangered. It is estimated that around 1,500 tamarins are living in the wild, with an additional 450 residing in zoos around the world. Because of zoos, the future for lion tamarins is much brighter. ZOOS SAVE SPECIES WITH SCIENCE! Black Howler Monkey Alouatta caraya Known for their booming vocalizations, howler monkeys howl to defend their territory from outsider groups. Male black howlers are larger in size and all black in color compared to the more golden-brown females. Our Howler Monkey’s: Hayden (Female): 12/10/2015 Helen (Female): 12/28/1994 Coquerel’s Sifaka Propithecus coquereli Sometimes referred to as the “dancing sifaka,” the sifaka lemur moves through a unique form of locomotion called vertical clinging and leaping. They can leap distances of over 30 ft! Sifakas tend to live in small social groups, where the females are dominant to the males. Our Sifakas: Rinaldo (Male): 8/2/2004 Bobby (Male): 9/3/2012 Andri (Male): 11/16/2013 Bonobo Pan paniscus Bonobos, like chimps, are one of our closest living relatives, sharing over 98% of the same DNA. Our Bonobos: Vernon (Male): 1/30/1972 Lana (Female): 4/13/1979 Vergil (Male): 1/24/1994 Vim (Male): 9/5/1995 Kimia (Female): 6/13/1999 Zanga (Female): 1/9/1999 Kesi (Female): 8/15/2004 Kenge (Female): 11/6/2009 Zeke (Male): 3/29/2010 Clara (Female): 5/27/2010 Kibibi (Female): 11/17/2013 Bolingo (Male): 3/16/2015 Coltan Mining and Bonobos Bonobos are Endangered, with populations continuing to decline. It is estimated as few as 50,000 individuals remain. A large reason for this is the loss of habitat due to the mining of coltan. Coltan is an ore that is an essential component of many electronic devices, including cellphones. To get coltan, large areas of forest must be cleared and the remaining soil mined to extract the valuable ore. This puts bonobos in great danger. By RECYCLING old cell phones, we can reduce the demand for mining coltan and help protect habitat in the wild for bonobos and other wildlife. The Cincinnati Zoo has collected and recycled over 70,000 cellphones! Angolan Colobus Monkey Colobus angolensis An oddity among other primate species, Colobus Monkeys actually lack thumbs! This special adaptation allows them to have almost hook like hands to help swing in the trees. They are also amazing leapers, and can jump over 30 feet at a time! Our Monkeys: Don King (Male): 10/29/1995 Cindy (Female): 7/4/2000 Potto Perodictus potto Using their powerful clamp like hands and feet, pottos move slowly through the forest trees, rarely coming to the ground. When frightened, pottos will freeze and hold very still to blend in, potentially for hours at a time! While slow moving, pottos can quickly catch small prey animals when needed. Our Pottos: Miwani (Female): 11/04/2009 Harry (Male): 12/2/2013 Otto (Male): 12/14/2015 Garnett’s Galago Otolemur garnetti The Garnett’s galago is also commonly known as the Greater Bushbaby due to its territorial vocalizations that sound like a child’s cry. These small, nocturnal, prosimians leap through the forest trees with amazing agility. Their large eyes help them to navigate in low light settings. Our Galagos: Sandy (Female): 11/20/2000 Andy (Male): 1/1/2001 Grey Bamboo Lemur Hapalemur griseus Like its name would imply, the bamboo lemurs feed mainly on bamboo, a plant which contains high amounts of toxic cyanide. Bamboo lemurs can eat these plants without experiencing its poisoning effects! Bamboo lemurs live in small groups of around four individuals, they often rely on scent marking to communicate with each other and rival groups. Our Grey Bamboo Lemur: Lil Bit (Female): 4/6/1999 “You cannot get through a single day without having an impact on the world around you. What you do makes a difference, and you have to decide what kind of difference you want to make.” “Only if we understand, can we care. Only if we care, we will help. Only if we help, shall all be saved.” ~ Jane Goodall Aye-Aye Daubentonia madagascariensis A very unique species of lemur, the aye-aye plays a similar role to woodpeckers in the forests of Madagascar. Aye-ayes are percussion foragers, they tap on the trees with their long and thin middle fingers to locate insects inside. Once found, aye-ayes use their rodent-like teeth to gnaw through the bark, and spear the larva with their finger. Our Aye-ayes: Medea (Female): 9/10/2004 Nify (Male): 6/21/2008 .

APPROVED BY MEM~ OF THE THESIS COMMITTEE: Marc R. Feldesman, Chairman Gibbon classification at the species and subspecies levels has been hotly debated for the last 200 years. This thesis explores the reasons for this debate. Authorities agree that siamang, concolor, kloss and hoolock are species, while there is complete lack of agreement on lar, agile, moloch, Mueller's and pileated. The disagreement results from the use and emphasis of different character traits, and from debate on the occurrence and importance of gene flow.

  • 7 Gibbon Song and Human Music from An
    Gibbon Song and Human Music from an 7 Evolutionary Perspective Thomas Geissmann Abstract Gibbons (Hylobates spp.) produce loud and long song bouts that are mostly exhibited by mated pairs. Typically, mates combine their partly sex-specific repertoire in relatively rigid, precisely timed, and complex vocal interactions to produce well-patterned duets. A cross-species comparison reveals that singing behavior evolved several times independently in the order of primates. Most likely, loud calls were the substrate from which singing evolved in each line. Structural and behavioral similarities suggest that, of all vocalizations produced by nonhuman primates, loud calls of Old World monkeys and apes are the most likely candidates for models of a precursor of human singing and, thus, human music. Sad the calls of the gibbons at the three gorges of Pa-tung; After three calls in the night, tears wet the [traveler's] dress. (Chinese song, 4th century, cited in Van Gulik 1967, p. 46). Of the gibbons or lesser apes, Owen (1868) wrote: “... they alone, of brute Mammals, may be said to sing.” Although a few other mammals are known to produce songlike vocalizations, gibbons are among the few mammals whose vocalizations elicit an emotional response from human listeners, as documented in the epigraph. The interesting questions, when comparing gibbon and human singing, are: do similarities between gibbon and human singing help us to reconstruct the evolution of human music (especially singing)? and are these similarities pure coincidence, analogous features developed through convergent evolution under similar selective pressures, or the result of evolution from common ancestral characteristics? To my knowledge, these questions have never been seriously assessed.

    The Ecology and Conservation of the Critically Endangered Cross River Gorilla in Cameroon By Sarah Cahill Sawyer A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in Charge: Professor Justin Brashares, Chair Professor Steve Beissinger Professor William Lidicker Fall 2012 The Ecology and Conservation of the Critically Endangered Cross River Gorilla in Cameroon © 2012 By Sarah Cahill Sawyer ABSTRACT: The Ecology and Conservation of the Critically Endangered Cross River Gorilla in Cameroon By Sarah Cahill Sawyer Doctor of Philosophy in Environmental Science, Policy, and Management University of California, Berkeley Professor Justin Brashares, Chair The Cross River gorilla (Gorilla gorilla diehli; hereafter: CRG) is one of the world’s most endangered and least studied primates. CRG exist only in a patchy distribution in the southern portion of the Cameroon-Nigeria border region and may have as few as 300 individuals remaining, divided into 14 fragmented subpopulations. Though Western gorillas (Gorilla gorilla spp) probably once inhabited much greater ranges throughout West Africa, today CRG represent the most northern and western distribution of all gorillas and are isolated from Western lowland gorilla populations by more than 250 km. CRG have proved challenging to study and protect, and many of the remaining subpopulations currently exist outside of protected areas. Very little is known about where the various subpopulations range on the landscape or why they occur in a patchy distribution within seemingly intact habitat. Active efforts are currently underway to identify critical habitat for landscape conservation efforts to protect the CRG in this biodiversity hotspot but, to date, a lack of understanding of the relationship between CRG ecology and available habitat has hampered conservation endeavors.

    International Journal of Primatology, Vol. 27, No. 2, April 2006 (C 2006) DOI: 10.1007/s10764-006-9024-5 Sumatran Orangutans and a Yellow-Cheeked Crested Gibbon Know What Is Where Marina Scheumann 1,2,3 and Josep Call1 Received September 14, 2004; revision January 9, 2005; accepted February 10, 2005; Published Online May 23, 2006 In their natural habitats orangutans and gibbons have to solve spatial prob- lems to find enough food, which is distributed over large areas and available at different times of the year. Therefore both species should evolve spatial memory skills to remember spatial locations and their content. We conducted 2 studies in a 1900-m2 naturalistic outdoor enclosure. In the 1st study, we hid kiwi pieces in 10 different locations and placed kiwi pieces in a visible location. Individuals of both species approached significantly more food lo- cations in the test condition than in the control condition in which no food was hidden. In the 2nd study, we hid 2 types of food in 10 different locations so that individuals had to remember which food type was where. We hid ba- nanas on trees (banana condition) and grapes under bamboo shrubs (grape condition). We also placed oranges in full view (control condition) to rule out the possibility that finding food may automatically trigger an indiscrimi- nate search. Individuals approached the banana locations more often in the banana than in the other 2 conditions. Some orangutans, but not the gibbon, also approached the grape locations more often in the grape than in the other 2 conditions.

Class: Mammalia (all mammals) Order: Primates (prosimians, monkeys, apes, humans) Family: Hylobatidae(gibbons and lesser apes) Genus: Nomascus (crested gibbons) Species: Nomascus leucogenys (Northern white cheeked gibbon) Distribution Where in the world does this species live? Nomascus leucogenys is better known as the white-cheeked gibbon. This species is found only in Southeast Asia. They primarily populate Laos, Vietnam, and Southern China. In Vietnam white-cheeked gibbons are found to the southwest of the Song Ma and Song Bo Rivers. Habitat What kinds of areas does this species live in? They live in the canopy of subtropical rainforests and prefer lowland forests with more diversity of fruit trees. However more recently with habitat loss most of these gibbons live above 700 meters.White- cheeked gibbons hardly ever descend to the forest floor. Physical Description How would this animal’s body shape and size be described? • Gibbons are small apes with very long arms and no tail. Nomascus leucogenys are not sexually dimorphic for size, but are for color. • Males and females are 45-63 cm (18-25 in) long and weigh and average of 5.7 kg.(12.5 lb). • All infants are born with cream-colored fur. At two years of age, the infants’ fur changes from cream to black, and they develop white patches on their cheeks. • At sexual maturity, males stay black with white cheeks. Females turn back to the original cream or pale yellow/yellow color and they lose the majority of their white cheek color, except for a thin white face ring.
