Olfactory discrimination in the western lowland gorilla, Gorilla gorilla gorilla
Primates, 2012The olfactory abilities of great apes have been subject to little empirical investigation, save for a few observational reports. This study, using an habituation/dishabituation task, provides experimental evidence for a core olfactory ability, namely, olfactory discrimination, in the gorilla.

Insectivory by Gorilla gorilla gorilla in Southeast Cameroon
International Journal of Primatology, 2003Our study extends quantitative analyses of insect-eating by gorillas (Gorilla gorilla gorilla) to Cameroon. During a 2-mo period (May–June 2001), we recorded and analyzed feeding traces on plants and insects and in gorilla feces. We found 180 feeding traces, 17% of which involved insectivory.

Another gorilla (Gorilla gorilla gorilla) recognizes himself in a mirror
American Journal of Primatology, 2006AbstractVarious attempts have been made to explain why gorillas (Gorilla gorilla gorilla) find it difficult to recognize their mirror image. One of the most oft‐cited reasons is aversion to eye contact, which stops gorillas from looking into a mirror and thus prevents them from carrying out a suitable exploration that could lead to self‐recognition. In

The hand-on gesture in gorillas (Gorilla gorilla)
Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systems, 2013The gestural repertoire of captive gorillas contains the so-called “hand-on” (or “pat-off”) gesture in which one animals puts its flat hand on top of another’s head, which often leads to cessation of the receiver’s previous activity. We investigate the origins of this gesture and developmental aspects of gesture creation.

Quantity estimation and comparison in western lowland gorillas (Gorilla gorilla gorilla)
Animal Cognition, 2013We investigated the quantity judgment abilities of two adult male western lowland gorillas (Gorilla gorilla gorilla) by presenting discrimination tasks on a touch-screen computer. Both gorillas chose the larger quantity of two arrays of dot stimuli. On some trials, the relative number of dots was congruent with the relative total area of the two arrays.

CLOSTRIDIUM SEPTICUM MYOSITIS IN A WESTERN LOWLAND GORILLA (GORILLA GORILLA GORILLA)
Journal of Zoo and Wildlife Medicine, 2005A 10-yr-old male gorilla (Gorilla gorilla gorilla) with a history of conspecific bite wounds was evaluated for acute onset of depression, anorexia, and right hemiparesis. The animal was immobilized for diagnostic examination and treatment for suspected toxic shock from a necrotizing, emphysematous wound infection, but was euthanized due to ...

OPHTHALMIC EXAMINATION OF THE CAPTIVE WESTERN LOWLAND GORILLA (GORILLA GORILLA GORILLA)
Journal of Zoo and Wildlife Medicine, 2005This study examined the captive western lowland gorilla (Gorilla gorilla gorilla) eye as compared and contrasted with the human eye. Bilateral ophthalmic examinations of western lowland gorillas (n = 5) while under general anesthesia were performed opportunistically, including slit-lamp biomicroscopy, dilated fundus examination, cycloplegic retinoscopy,

Adoption of an Additional Infant by a Western Lowland Gorilla (Gorilla gorilla gorilla)
Folia Primatologica, 1992A 10-year-old Western lowland gorilla, already caring for her own 14-month-old son, adopted a female neonate. The infant’s mother (aged 7 years, 4 months) showed no interest in the infant, and it is unclear whether she abandoned the infant or whether it was seized by the dominant foster-mother.

Endowment effects in gorillas (Gorilla gorilla).
Journal of Comparative Psychology, 2013Reports of endowment effects in nonhuman primates have received considerable attention in the comparative literature in recent years. However, little is known about the mechanisms underlying these effects. Continuing to explore endowment effects across different species of primate may reveal subtle differences in behavior that can help formulate ...
