23-10-2019 BIOPARC, VALENCIA - AFRICAN SACRED IBIS (Threskiornis aethiopicus ssp. aethiopicus)

The African sacred ibis (Threskiornis aethiopicus) is a striking wading bird from the family Threskiornithidae. It is characterized by its all-white plumage, save for the dark plumes on its rump. The adult bird measures approximately 68 cm (27 in) in length, with a wingspan ranging from 112 to 124 cm (44 to 49 in), and weighs between 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females. The species is distinguished by its bald head and neck, thick curved bill, and black legs. In flight, the white wings reveal a contrasting black rear border. The eyes are brown, encircled by a dark red orbital ring.

When identifying the African sacred ibis, look for the combination of its white body, black head, neck, and bill. Juveniles can be recognized by their less pristine white plumage, smaller bill, and some feathering on the neck. The presence of greenish-brown scapulars and more black on the primary coverts also helps to distinguish younger birds.

This ibis favors marshy wetlands and mud flats, both inland and along the coast. It is often found nesting in trees near water and is known to frequent very shallow wetlands, wet pastures with soft soil, cultivation areas, and rubbish dumps.

The African sacred ibis is indigenous to Sub-Saharan Africa and parts of the Middle East, including small regions of Iraq, Iran, and Kuwait. The species has migratory populations that move with the rains, with some South African birds traveling as far north as Zambia, while those north of the equator migrate in the opposite direction.

The species has been introduced to various parts of Europe, including Italy, France, and the Netherlands, as well as to Florida, Taiwan, and the United Arab Emirates. In Europe, it is considered an invasive species.

The African sacred ibis is a social bird, often seen in flocks. It is predominantly silent, but can occasionally emit puppy-like yelping sounds. The species is known for its predatory feeding habits, which occur mainly during the day.

This species is usually silent, but may occasionally make puppy-like yelping noises.

Breeding occurs once a year during the wet season, with the season spanning from March to August in Africa and from April to May in Iraq. The ibis builds a stick nest, often in a baobab tree, and nests in colonies alongside other large wading birds. Females lay one to five eggs, which are incubated by both parents for 21 to 29 days. Chicks fledge after 35 to 40 days and reach sexual maturity between one to five years after hatching.

The African sacred ibis is closely related to the black-headed ibis and the Australian white ibis, with which it forms a superspecies complex. These species can hybridize in mixed flocks.

The diet of the African sacred ibis consists mainly of insects, worms, crustaceans, molluscs, fish, frogs, reptiles, small mammals, and carrion. It uses its long beak to probe the soil for invertebrates and may also feed on seeds.

The IUCN classifies the African sacred ibis as "Least Concern," with an estimated global population of 200,000–450,000 individuals. However, the population appears to be decreasing. The species is covered by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

23-10-2019 BIOPARC, VALENCIA - THOMSON'S GAZELLE (Eudorcas thomsonii)

Thomson's gazelle (Eudorcas thomsonii) is one of the best known species of gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus Gazella within the subgenus Eudorcas, before Eudorcas was elevated to genus status.

Thomson's gazelles can be found in numbers exceeding 200,000 in Africa and are recognized as the most common type of gazelle in East Africa. A small fast antelope, the Thomson's gazelle is said to have top speeds up to 80–90 km/h (50–55 mph). It is the fourth-fastest land animal, after the cheetah (its main predator), pronghorn, and springbok.

Thomson's gazelle is a relatively small gazelle; it stands 60–70 cm (24–28 in) at the shoulder. Males weigh 20–35 kg (44–77 lb), while the slightly lighter females weigh 15–25 kg (33–55 lb). Facial characteristics of the gazelle include white rings around the eyes, black stripes running from a corner of the eye to the nose, rufous stripes running from the horns to the nose, a dark patch on the nose, and a light forehead.

The coat is sandy brown to rufous; a black band runs across the flanks, from the upper foreleg to just above the upper hind leg. A buff band occurs above the black stripe. Short, black streaks mark the white rump. The black tail measures 15–27 cm (5.9–10.6 in). Males have well-developed preorbital glands near the eyes, which are used for scent-marking territories. Both sexes possess horns that curve slightly backward with the tips facing forward. The horns, highly ringed, measure 25–43 cm (9.8–16.9 in) in males and 7–15 cm (2.8–5.9 in) in females. However, females have more fragile horns; some are even hornless. Grant's gazelle is very similar to Thomson's gazelle, but can be differentiated by its larger size and the white patch on the rump extending top over the tail.

The two subspecies differ in their appearance. The eastern Thomson's gazelle is the larger of the two, with fainter facial markings. The Serengeti Thomson's gazelle has a whiter face with more conspicuous markings. The horns of females are shorter than those of males to a greater degree in the eastern Thomson's gazelle and the horns are more divergent in the eastern Thomson gazelle.

Thomson's gazelle lives in East Africa's savannas and grassland habitats, particularly the Serengeti region of Kenya and Tanzania. It has narrow habitat preferences, preferring short grassland with dry, sturdy foundation. It does, however, migrate into tall grassland and dense woodland. Gazelles are mixed feeders. In the wet seasons, they eat mainly fresh grasses, but during the dry seasons, they eat more browse, particularly foliage from woody plants bushes and herbaceous forbs.

Cheetahs are the main predators of Thomson's gazelle.

Thomson's gazelles are dependent on short grass. Their numbers can be highly concentrated at the beginning of the rains when the grass grows quickly. In the Serengeti, they follow the larger herbivores, such as plains zebras and blue wildebeests as they mow down the taller grasses. In the wild, Thomson's gazelles can live 10–15 years. Their major predators are cheetahs, which are able to attain higher speeds, but gazelles can outlast them in long chases and are able to make turns more quickly. This small antelope can run extremely fast, up to 80 km/h (50 mph), and zigzag, an adaptation which often saves it from predators. Sometimes, they are also taken by leopards, lions, African wild dogs, hyenas, Nile crocodiles and African rock pythons, and their fawns are sometimes the prey of eagles, jackals, and baboons. A noticeable behaviour of Thomson's gazelles is their bounding leap, known as stotting or pronking, used to startle predators and display strength.

During the wet season, a time when grass is abundant, adult male gazelles graze extensively. They spread out more and establish breeding territories. Younger males usually spend their time in bachelor groups, and are prevented from entering the territories. Females form migratory groups that enter the males' territories, mostly the ones with the highest-quality resources. As the female groups pass through and forage, the territorial males may try to herd them, and are usually successful in preventing single females from leaving, but not whole groups. Subadult males usually establish dominance through actual combat, while adults are more likely to do rituals. If a bachelor male should be passing through a territorial male's region, the male will chase the offender out of his territory.

When patrolling his territory, a male may use his horns to gore the grass, soil, or a bush. Males also mark grass stems with their preorbital glands, which emit a dark secretion. Territories of different males may share a boundary. When territorial males meet at the border of their territories, they engage in mock fights in which they rush towards each other as if they are about to clash, but without touching. After this, they graze in a frontal position, then in parallel and then in reverse, and move away from each other while constantly grazing. These rituals have no victor, but merely maintain the boundaries of the territories. Territorial males usually do not enter another male's territory. If a male is chasing an escaping female, he will stop the chase if she runs into another territory, but the neighboring male will continue the chase.

23-10-2019 BIOPARC, VALENCIA - EURASIAN MAGPIE (Pica pica)

The Eurasian magpie, or common magpie (Pica pica), is a striking bird that graces the northern reaches of the Eurasian continent. It is a member of the crow family, known as corvids, and is part of the "monochrome" magpie group within the Holarctic radiation. The bird is easily recognized by its black and white plumage and long, iridescent tail.

Adult Eurasian magpies measure 44–46 cm in length, with over half of this being the tail. They have a wingspan of 52–62 cm. The head, neck, and breast are glossy black with a metallic sheen of green and violet, while the belly and scapulars are pure white. The wings are black with green or purple gloss, and the primaries have white inner webs. The tail is black with green and reddish-purple gloss. Both sexes have similar plumage, though females are slightly smaller.

The Eurasian magpie favors open countryside with scattered trees, avoiding dense forests and treeless areas. It adapts well to suburban environments, including parks and gardens, and can be found in city centers.

This magpie's range spans temperate Eurasia from the western edges of Portugal and Spain to the eastern limits of the Kamchatka Peninsula.

23-10-2019 BIOPARC, VALENCIA - IMPALA (Aepyceros melampus)

The impala (Aepyceros melampus) is a medium-sized antelope that is found in Africa. It was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. The impala is known for two characteristic leaps that constitute an anti-predator strategy.

Impala is an elegant and magnificent species of antelope. The animal has slender body with the identifying "M"-like marking on the rear. This medium-sized antelope possesses thin, pointed horns with tips, lying far apart from each other. Males of this species are identified by the characteristic "S"-like horns. The elegant limbs of these animals have scent glands behind the ankles. The overall coloration of their fur is red-brown with paler sides. In addition, they have black and white colored areas on their body. Thus, the tail, belly, chin, lips, inside ears as well as the lines above the eyes are colored with white. Meanwhile, black bands cover their thighs, tail, forehead and ear tips.

Impalas are distributed throughout the northeastern part of South Africa, Angola, southern Rwanda, Uganda, and Kenya. Close proximity to a water source is an important life condition for these animals. Generally, they prefer woodland with little undergrowth as well as low to medium-height grassland.

Impalas have polygynous mating system, where each male mates with a number of females. The period of peak breeding activity is March-May. During this period, pregnant females live in isolation to give birth. The gestation period lasts from 194 to 200 days, yielding a single calf, which weighs about 5kgs (11 lbs). After a few days, the calf and the female rejoin the herd. Then, after a while, the calf joins a crèche of other young impalas. They are weaned at 4-5 months old. Male impalas reach reproductive maturity at 1 year of age, while females are ready to breed when they are between 1 and 2 years old. Becoming reproductively mature, they, however, do not rush to establish territories. They typically start mating only at 4 years old.

These antelopes are both diurnal and nocturnal. They are most active just after sunrise and before sunset, socializing and moving with their herd, whereas, during the nighttime hours, impalas usually lie down and ruminate. Female impalas and their offspring gather into herds, containing from 15 to 100 individuals. The home range of each herd covers a territory, varying from 80 to 180 hectares. During the wet season, females become highly territorial, defending home ranges of their herds. On the other hand, young males form bachelor, non-territorial herds of up to 30 individuals. During the dry season, male and female herds can often be seen mixed together. Home ranges of mature breeding males vary from season to season. Thus, during the breeding season, they usually have smaller home ranges, which they fiercely defend. Males use a wide variety of methods to defend their home range, including fighting, tail-raising, chasing, roaring, erect posture as well as forehead marking and forehead rubbing.

The animals presently suffer from the fragmentation of their range due to the development of human settlements. In addition, roads such as the Serengeti Highway in Tanzania have an extremely negative effect, making it difficult for scattered migrating populations to move between parks, where the antelopes feed, mate and give birth. In addition, populations in South Africa are exposed to hunting for their meat by local people.

23-10-2019 BIOPARC, VALENCIA - BONTEBOK (Damaliscus pygargus)

The bontebok (Damaliscus pygargus) is an antelope found in South Africa, Lesotho and Namibia. D. pygargus has two subspecies; the nominate subspecies (D. p. pygargus), occurring naturally in the Fynbos and Renosterveld areas of the Western Cape, and the blesbok (D. p. phillipsi) occurring in the Highveld.

The bontebok is related to the common tsessebe.

The bontebok is a tall, medium-sized antelope. They typically stand 80 to 100 cm (31 to 39 in) high at the shoulder and measure 120 to 160 cm (47 to 63 in) along the head and body. The tail can range from 30 to 60 cm (12 to 24 in). Body mass can vary from 50 to 68 kg (110 to 150 lb). Males are slightly larger and noticeably heavier than females.[4] The bontebok is a chocolate brown colour, with a white underside and a white stripe from the forehead to the tip of the nose, although there is a brown stripe across the white near the eyes in most blesbok. The bontebok also has a distinctive white patch around its tail (hence the Latin name), while this patch is light brown/tan in the blesbok. The horns of the bontebok are lyre-shaped and clearly ringed. They are found in both sexes and can reach a length of half a metre.

Blesbok live in the Highveld, where they eat short grasses, while bontebok are restricted to the coastal Fynbos and the Renosterveld. They are diurnal, though they rest during the heat of the day. Herds may contain only males, only females, or be mixed, and do not exceed 40 animals for bontebok or 70 for blesbok.

Bontebok are not good jumpers, but they are very good at crawling under things. Mature males form territories and face down other males in displays and occasionally fight them.

Bontebok were once extensively killed as pests, and by the early 20th century were reduced to a wild population of just 17 individuals. The species was saved from certain extinction when Dutch farmer Alexander van der Bijl corralled the remaining individuals into a fence, which they were unable to jump out of. In 1931, this herd of 17 was transferred to Bontebok National Park, which was established for the explicit purpose of conservation of the species. By the time the park was relocated to better suit the needs of the bontebok in 1961, the herd had grown to 61 members. Today, their population is estimated to range from 2,500 to 3,000, all descendants of the original herd of 17 members.

While Bontebok are extinct in their natural habitat, they have increased in population to the point where they are now very abundant and avidly farmed, because they are popular quarry for hunters and are easy to sustain.

The bontebok is the provincial animal of Western Cape.

23-10-2019 BIOPARC, VALENCIA - PINK BACKED PELICAN (Pelecanus rufescens)

It is smaller and stockier than the common pelican, its plumage is light with a pinkish-gray hue. The primary and secondary feathers are chestnut gray. It measures 125-132 cm, with a wingspan of 215 to 290 cm and weight is 4 to 7 Kg.

The beak, legs and feet are pink. Adults have a tuft of longer feathers on their heads.

They carry out migratory movements depending on the rains and the abundance of food.

They form small breeding colonies of 20 to 500 pairs, which do not necessarily settle near water, and place their nests of branches on vegetation, which can be trees, bushes and mangroves. Often these colonies are made in the company of other large birds. They lay two to four slightly bluish white eggs.

Active during the day at first and last hour of the day, although they usually fish on full moon nights.

23-10-2019 BIOPARC, VALENCIA - SADDLE BILLED STORK (Ephippiorhynchus senegalensis)

The Saddle-billed Stork, known scientifically as Ephippiorhynchus senegalensis, is a magnificent and large wading bird belonging to the stork family, Ciconiidae. It stands tall, reaching heights of 145 to 150 cm (4 ft 9 in to 4 ft 11 in), with a wingspan stretching an impressive 2.4 to 2.7 m (7 ft 10 in to 8 ft 10 in). The male of the species is typically larger and heavier than the female, with weights ranging from 5.1 to 7.52 kg (11.2 to 16.6 lb).

Distinguishing between the sexes is straightforward; the female boasts golden yellow irises, while the male has brown irises complemented by dangling yellow wattles. Both sexes share a striking plumage, with iridescent black covering the head, neck, back, wings, and tail, and the rest of the body along with primary flight feathers being white. The juvenile birds wear a more subdued brownish-grey attire. The stork's bill is a vivid red adorned with a black band and a distinctive yellow frontal shield, the namesake "saddle." Their legs and feet are black with pink hocks, and a bare red patch of skin can be found on the chest, which intensifies in color during the breeding season.

Saddle-billed Storks have a preference for protected areas abundant in open water, such as national parks and protected swamps, which provide safer environments for both the birds and ornithologists.

This species is a resident breeder in sub-Saharan Africa, with its range extending from Sudan, Ethiopia, and Kenya in the east, down to South Africa, and also found in The Gambia, Senegal, Côte d'Ivoire, and Chad in West Africa.

30-9-2019 SEGOVIA, ESPANA - EUROPEAN ROBIN (Erithacus rubecula)

23-10-2019 BIOPARC, VALENCIA - AFRICAN ELEPHANT (Loxodonta africana)

African elephants are members of the genus Loxodonta comprising two living elephant species, the African bush elephant (L. africana) and the smaller African forest elephant (L. cyclotis). Both are social herbivores with grey skin, but differ in the size and colour of their tusks and in the shape and size of their ears and skulls.

Both species are considered at heavy risk of extinction on the IUCN Red List; as of 2021, the bush elephant is considered endangered and the forest elephant is considered critically endangered. They are threatened by habitat loss and fragmentation, and poaching for the illegal ivory trade is a threat in several range countries as well.

Loxodonta is one of two extant genera of the family Elephantidae. The name refers to the lozenge-shaped enamel of their molar teeth. Fossil remains of Loxodonta species have been excavated in Africa, dating to the Middle Pliocene.

African elephants are distributed in Sub-Saharan Africa, where they inhabit Sahelian scrubland and arid regions, tropical rainforests, mopane and miombo woodlands. African forest elephant populations occur only in Central Africa.

23-10-2019 BIOPARC, VALENCIA - RED CRESTED POCHARD (FEMALE) (Netta rufina)

The Red-crested Pochard, Netta rufina, is a striking large diving duck. Its name is drawn from the Greek word for duck, 'Netta', and the Latin 'rufina', meaning 'golden-red', a nod to the male's vibrant plumage.

Males are resplendent with a rounded orange head, a red bill, and a contrasting black breast. Their sides are a crisp white, with a brown back and a black tail. Females, on the other hand, are clad in more subdued tones, primarily pale brown with a darker back and crown, and a whitish face. During eclipse, males resemble females but retain their red bills.

These ducks favor lowland marshes and lakes, thriving in the wetland habitats of southern Europe.

The Red-crested Pochard breeds from the steppe and semi-desert regions near the Black Sea to Central Asia and Mongolia. It is a somewhat migratory species, with northern populations wintering in the Indian Subcontinent and Africa.

Gregarious by nature, Red-crested Pochards form large flocks in the winter, often mingling with other diving ducks such as the Common Pochard. They are known to both dive and dabble for their food.

The male emits a distinctive wheezing 'veht', while the female can be heard making a series of hoarse 'vrah-vrah-vrah' calls.

Nests are constructed lakeside amidst vegetation, where they lay clutches of 8–12 pale green eggs.

While unique in appearance, the male Red-crested Pochard can be confused with other pochards during eclipse plumage, but the red bill is a distinguishing feature.

Their diet consists mainly of aquatic plants. These ducks are adept at upending in the water, a method they use more frequently than most diving ducks to forage for food.

The Red-crested Pochard is classified as Least Concern by the IUCN, and it is also a species protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

23-10-2019 BIOPARC, VALENCIA - RED CRESTED POCHARD (MALE) (Netta rufina)

23-10-2019 BIOPARC, VALENCIA - VERREAUX'S EAGLE OWL (Bubo lacteus)

Verreaux's eagle-owl (Ketupa lactea), also commonly known as the milky eagle owl or giant eagle owl, is a member of the family Strigidae. This species is widespread in sub-Saharan Africa. A member of the genus Ketupa, it is the largest African owl, measuring up to 66 cm (26 in) in total length. This eagle-owl is a resident primarily of dry, wooded savanna. Verreaux's eagle-owl is mainly grey in color and is distinguishable from other large owls by its bright pink eyelids, a feature shared with no other owl species in the world.

Verreaux's eagle-owl is a highly opportunistic predator equipped with powerful talons. Just over half of its known diet is composed of mammals but equal or even greater numbers of birds and even insects may be hunted locally, along with any other appropriately sized prey that is encountered. This species is considered of Least Concern by IUCN as it occurs over a wide range and has shown some adaptability to human-based alterations and destruction of habitat and adaptability to diverse prey when a primary prey species declines in a region. As a large, highly territorial species of owl, it does, however, occur at fairly low densities and some regional declines have been reported.

23-10-2019 BIOPARC, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.

The call of the White Wagtail is a sharp "chisick," softer than that of the Pied Wagtail. Its song is more structured and is used by males to attract females rather than to mark territory.

White Wagtails are monogamous breeders, with both sexes contributing to nest building. The nest is often placed in crevices or holes near water or in human-made structures. The species lays three to eight cream-colored, speckled eggs, which both parents incubate. Chicks fledge after 12 to 15 days and continue to be fed for a week thereafter.

The Pied Wagtail, particularly the subspecies M. a. yarrellii, is similar but has a darker back and is found in Great Britain and Ireland. Other subspecies vary in wing, back, and head coloration.

The diet of the White Wagtail primarily consists of insects and small invertebrates, including beetles, dragonflies, flies, and crustaceans. It continues to feed on insects even in winter, unlike many other insectivorous birds in temperate climates.

The White Wagtail is classified as Least Concern by the IUCN. Its population is large and stable, and the species has adapted well to human-altered landscapes. However, it faces threats from being kept as pets, used for food, and potentially from climate change affecting migration patterns.

The White Wagtail is the national bird of Latvia and has been depicted on the postage stamps of several countries. It is celebrated in Latvian folk songs and holds a special place in the cultural heritage of the regions it inhabits.

23-10-2019 BIOPARC, VALENCIA - WESTERN GORILLA (Gorilla gorilla)

The western gorilla (Gorilla gorilla) is a great ape found in Africa, one of two species of the hominid genus Gorilla. Large and robust with males weighing around 168 kilograms (370 lb), the species is found in a region of midwest Africa, geographically isolated from the eastern gorilla (Gorilla beringei). The hair of the western species is significantly lighter in color.

The western gorilla is the second largest living primate after the eastern gorilla. Two subspecies are recognised: the western lowland gorilla (Gorilla gorilla gorilla) is found in most of West Africa; while the Cross River gorilla (Gorilla gorilla diehli) is limited to a smaller range in the north at the border of Cameroon and Nigeria. Both subspecies are listed Critically Endangered.

Western gorillas are generally lighter colored than eastern gorillas. Western gorillas have black, dark grey or dark brown-grey hair with a brownish forehead. Males average 167 cm (5 ft 6 in) although reaching a height up to 176 cm (5 ft 9 in), with males weighing 145 to 191 kilograms (320 to 421 lb) and females weighing 58 to 72 kilograms (128 to 159 lb). Captive western gorillas average 157 kg (346 lb) in males and 80 kg (176 lb) in females. Another source[which?] describes the weight of wild male western lowland gorillas as 146 kg (322 lb).[9] The Cross River gorilla differs from the western lowland gorilla in both skull and tooth dimensions.

Western gorillas live in groups that vary in size from two to twenty individuals. Such groups are composed of at least one male, several females and their offspring. A dominant male silverback heads the group, with younger males usually leaving the group when they reach maturity. Females transfer to another group before breeding, which begins at eight to nine years old; they care for their young infants for the first three to four years of their lives. The interval between births, therefore, is long, which partly explains the slow population growth rates that make the western gorilla so vulnerable to poaching. Due to the long gestation time, long period of parental care, and infant mortality, a female gorilla will only give birth to an offspring that survives to maturity every six to eight years. Western gorillas are long-lived and may survive for as long as 40 years in the wild. A group's home range may be as large as 30 km2 (12 sq mi), but is not actively defended. Wild western gorillas are known to use tools.

Western gorillas' diets are high in fiber, including leaves, stems, fruit, piths, flowers, bark, invertebrates, and soil. The frequency of when each of these are consumed depends on the particular western gorilla group and the season. Furthermore, different groups of western gorillas eat differing numbers and species of plants and invertebrates, suggesting they have a food culture. Fruit comprises most of the western lowland gorillas' diets when it is abundant, directly influencing their foraging and ranging patterns. 

There is a correlation between the amount of time a western gorilla travels and the season in which fruits are available. Western gorillas spend more time traveling and feeding during the seasons when fruits are abundant compared to when there is less fruits available. Fruits of the genera Tetrapleura, Chrysophyllum, Dialium, and Landolphia are favored by the western gorillas. Low-quality herbs, such as leaves and woody vegetation, are only eaten when fruit is scarce. In the dry season from January to March, when fleshy fruits are few and far between, more fibrous vegetation such as the leaves and bark of the low-quality herbs Palisota and Aframomum are consumed. Of the invertebrates consumed by the western gorillas, termites and ants make up the majority. Caterpillars, grubs, and larvae are also consumed in rarity.
