The objective of this paper is to collate information on western gorilla diet from six study sites throughout much of their current range, including preliminary information from two sites (Afi and Lossi), where studies of diet have begun only recently. Food lists were available from each site, derived from indirect signs of gorilla feeding (such as feces), with some observational data. Important staple, seasonal, and fallback foods have been identified, and a number of striking similarities… 
Food preferences of wild mountain gorillas
TLDR
The results indicate that protein and sugar are important in the diets of gorillas, and that the gorillas fulfil these nutritional requirements through a combination of different plant parts, shedding new light on how gorillas balance their diets in a variable environment.
Nutritional composition of the diet of the western gorilla (Gorilla gorilla): Interspecific variation in diet quality
TLDR
The results suggest that interspecific differences in nutrient intake and food quality may shape differences in gorilla nutrient balancing and female life history strategies.
RESEARCH ARTICLE Food Preferences of Wild Mountain Gorillas
TLDR
The results indicate that protein and sugar are important in the diets of gorillas, and that the gorillas fulfil these nutritional requirements through a combination of different plant parts, shedding new light on how gorillas balance their diets in a variable environment.
Nutritional composition of the diet of the gorilla (Gorilla beringei): a comparison between two montane habitats
TLDR
It is demonstrated that gorillas consume diets that differ by plant species and part, but contain similar concentrations of nutrients, suggesting that classifying animals by broad dietary strategy does not provide a reliable indicator of the nutritional quality of their diet, and that previous assumptions about these categories should be re-evaluated.
The development of feeding behaviour in wild western lowland gorillas ( Gorilla gorilla gorilla )
TLDR
Results indicated that independent feeding skills were acquired by the end of infancy and did not undergo significant change beyond this point, suggesting that some continued investment by the mother was necessary until the strength and skills of immatures developed, perhaps to enable self-sufficiency through periods of succulent fruit scarcity.
Termite Feeding by Gorilla gorilla gorilla at Bai Hokou, Central African Republic
TLDR
This study of 2 well monitored groups of western gorillas at Bai Hokou in Dzanga-Ndoki National Park, Central African Republic provides information on frequency and variability of termite consumption (the most commonly eaten insect) as well as some of the first direct observations of the behavior.
Fallback foods and dietary partitioning among Pan and Gorilla.
TLDR
Although there was extensive overlap in the preferred fruits of these two species, gorillas tended to consume fewer fruits with prolonged availability while chimpanzees consumed fruits with large seasonal fluctuations, which shaped different social features between sympatric gorillas and chimpanzees.
Feeding Ecology of Cross River Gorillas (Gorilla gorilla diehli) at Mawambi Hills: The Influence of Resource Seasonality
TLDR
It is suggested that tree leaves and lianas are important fallback food sources in the gorilla diet in seasonally dry forests.
Male and female western gorilla diet: preferred foods, use of fallback resources, and implications for ape versus old world monkey foraging strategies.
TLDR
It is found that western gorillas, like other apes, are highly selective ripe fruit specialists, seeking fruit high in energy, low in antifeedants, and rare in the environment.
Food transfers in immature wild western lowland gorillas (Gorilla gorilla gorilla)
TLDR
The results point to the functional significance of food transfers in western lowland gorillas being informational, in a bai environment, where one species forms the majority of a visiting gorilla’s diet despite other species being available.

Western lowland gorilla diet and resource availability: New evidence, cross‐site comparisons, and reflections on indirect sampling methods
TLDR
The densities of these two species are similar across sites for which data are available, in spite of major differences in forest structure, suggesting they may be key species in determining gorilla density.
Composition of the diet of lowland gorillas at Lopé in Gabon
TLDR
This report describes the composition of the diet of lowland gorillas, Gorilla gorilla gorilla, at Lopé in central Gabon, which is the most frugivorous population studied so far.
The primate community of the Lopé reserve, Gabon: Diets, responses to fruit scarcity, and effects on biomass
TLDR
The most likely explanation of low primate biomass is the occurrence of an ecological “catastrophe” in the fairly recent past from which populations have not yet recovered.
Composition of the diet of chimpanzees and comparisons with that of sympatric lowland gorillas in the lopé reserve, gabon
TLDR
The major differences between chimpanzee and gorilla diet at Lopé were the larger quantities of vegetative foods regularly eaten by gorillas and their ability to resort to a diet dominated by vegetative Foods when fruit was scarce, and the diets of the two species showed greatest divergence.
Gorilla diet in the Lopé Reserve, Gabon:
TLDR
It is concluded that gorillas exploit the broad frugivore niche in West African lowland forests, and are part of the frugavore community there.

TLDR
The gorillas studied at Bai Hokou, Central African Republic, between August 1990 and October 1992 consumed 239 kinds of foods from 138 species of plants and invertebrates, including the fruits of 77 species, which shaped the foraging and ranging patterns of western lowland gorillas.

Food selection by western gorillas (G.g. gorilla) in relation to food chemistry
TLDR
Analysis of food chemistry in relation to food preference indicates that lignin, digestibility and crude protein are the most significant factors in food selection for western gorillas at this site.

Recent studies demonstrate that western lowland gorillas incorporate much more fruit into their diet than Virunga mountain gorillas do. Very little is known, however, about how the frugivorous
Mineral content as a basis for food selection by western lowland gorillas in a forest clearing
TLDR
Results suggest that the mineral content (especially in Na, Ca, and/or K) could determine the feeding selectivity of gorillas at the clearing, and tend to confirm that the amount of fiber plays a deterrent role in food selectivity, as has been found by many authors.
