Monkey species in Egypt lived on fruit 30 million years ago

It is hard to believe that habitats like this could possible have previously held rainforest which produces enough soft fruit for monkeys like this. Just 10,000 years ago crops were a new thing, in the same way that cows and other livestock farming. Before this, we had to hunt for virtually everything.

The reason that they can work out what monkeys ate, is because they have seen the teeth, and they were not chipped at all, as a result of soft diet. There are thought to have been roughly 5 species of this small monkey family living at the time (30 million years ago). This is new, as formerly it was thought that early primates ate some fruit but also harder foods – clearly they specialized in fruit earlier than we thought.

Black and gold howler monkeys avoid power cables when they can in Paraguay.

Many species of primate within the Amazon rainforest has become quite content moving around in human areas, as they have sprung up fast across the region.

Yet, these cables are not surprisingly dangerous, carrying high voltage. As such, in some places an alarming number of them die as a result.

As these towns are built within the Amazon, we must make sure that it does not kill wildlife that wanders into town

The Red colobus group (genus Piliocolobus)

The red colobus group is one which has had a surprising number of new species discovered in recent decades. Being primates, they are usually fascinating and you can sit and watch them for lots of time. There are many groups that have been isolated in small fragments of forest, which makes conservation hard.

Little clear information is there on many of these species, perhaps unsurprisingly, given how long they managed to stay under the radar. I have attempted to include a video with each. Some are short clips of the animal, one is the search for a close to extinction (miss waldrons) and several is simple some information over images.

As with similar groups of animals, as the links for each of these species start arriving, they will be given an entire page of their own. Help this be required as soon as possible.

Bouviers red colobus monkey: 

Not having been seen for 4 decades until 2015, they are restricted to 3 small areas (this map is the DRC) in purple highlighted. First described in 1887 it was considered a subspecies of Pennants colobus, but was reassessed as separate species in 2007.

In 2008 and 2016 it was assessed as critically endangered, and none have been seen in the wild since 1970. A few possible sightings in the 2000 were further south than previously known.

In 2019 the IUCN reclassified it as endangered because of “known populations in norther DRC”. It is still rarely sighted despite many surveys

Ugandan red colobus monkey: 

Also known as the ashy red colobus, it was recognized as a separate species (up from being a subspecies of the western red colobus monkey) in 2001, though there are still plenty of experts who disagree with this change. It is found in 1 regions of Uganda (17,000 alone) and 4 regions of Tanzania.  Possible it may be found in Rwanda, Burundi and the eastern Democratic Republic of the Congo. Males weigh around 10kg, with the females weighing 7kg.

As you will see, it is one of the possible subspecies of the Central Africa red colobus. Time will tell.

 

There are thought to be around 20,000 left in the wild, and are classed as endangered, though it is listed as having declined my 89% (presumably since 2001 when it was declared a separate species.

Central African red colobus monkey:  

This species does not appear to be an individual species, rather a general name that many of the above species have at one time been grouped with. These include

  • Foa’s red colobus 
  • Lang’s red colobus 
  • Oustalet’s red colobus 
  • Lomami red colobus 
  • Tana River red colobus 
  • Semliki red colobus 
  • Ugandan red colobus 
Due to these species being listed here, they will not be covered separately (unless their status changes).

Niger Delta red Colobus monkey: Found in Southern Nigeria, it was originally considered a subspecies of the western red colobus, then considered a subspecies of Pennants red colobus. There are only thought to be 50 left. Below is a 4 minute video from its habitat which shows it in the wild – makes me want to be there.

Pennants colobus monkey: 

Preuss red colobus monkey: 

Tholon (or Tshuapa) red colobus monkey: 

Western red colobus monkey: 

Zanzibar red colobus monkey: Found on the southern half of the main island of the Zanzibar archipelago (Unguja), it is also known as the Kirk redo colobus, after the discoverer. Classified as endangered in the mid 1990s, its population is still decreasing. It is believed to have been isolated when sea levels rose after the last ice age – however, as with other species trapped like this, they can evolve fast. Genetic analysis suggests a split 600,000 years ago.

The local word for it means poison monkey, due to its bad smell, this has lead to some targeting. 1600-3000 survive, with about half in protected areas.

Udzungwa red colobus monkey: (other names include the Uzungwa red colobus or Iringa red colobus) It is endemic to riverine and montane forest in the Udzungwa Mountains in Kilolo District of Iringa Region in Tanzania. It is threatened by habitat loss, though most of the land it is found on is protected (90% falls within the Udzungwa national park, I have seen one while visiting). Of course the problem with this, is that its range is not large, so it can never have a large population. 

The current population is roughly 15,400. The IUCN ranks this species as endangered

Miss Waldrons red colobus monkey: Native to west Africa, it was previously considered a subspecies of the wester red colobus monkey. It has not been officially sighted since 1978 and was considered extinct in 2000, however, new evidence suggests that a very small number of these monkeys may be living in the southeast corner of Côte d’Ivoire. The IUCN Red List notes Miss Waldron’s red colobus as critically endangered.

High-canopy forests (rainforests) in Ghana and Côte d’Ivoire serve as the exclusive habitat of Miss Waldron’s red colobus. The monkey usually formed large family groups of 20 or more. It is a social and highly vocal animal, frequently communicating with others using loud calls, shrieks and chattering. It eats fruit seeds and canopy leaves, and is eaten in turn, by western chimpanzee leopard and python.

It was the first primate classed as extinct in the 21st century. However, evidence collected are highly compelling.

However, primatologist W. Scott McGraw from Ohio State University has been collecting evidence of the monkey’s continued existence during his expeditions to Côte d’Ivoire over the past several years:

  • In 2000, McGraw was given a black monkey tail which DNA tests proved to be from a red colobus. The hunter who gave McGraw the tail claimed he had shot the monkey the previous year.
  • In 2001, an Ivorian hunter gave McGraw a piece of reddish monkey skin also believed to have come from Miss Waldron’s red colobus.
  • Also in 2001, McGraw received  a photograph of what appeared to be an adult Miss Waldron’s red colobus which had been killed. Experts who have examined the photograph attest to its likely authenticity. 

Presumably, a relict population of the monkey still is found in the Ehy Forest (also Ehi or Tanoé Forest) near the mouth of the Tano River into Ehy Lagoon, at the border between Côte d’Ivoire and Ghana. Miss Waldron’s Red Colobus is among the 25 “most wanted lost” species that are the focus of Re:wild’s “Search for Lost Species” initiative. 

Whether a surviving population will be found, or if there are just a handful left, we will have to wait and see. The Below video is from this area, while it is in Hindi, it is worth watching with the subtitles on.

Agile Mangabey

Agile Mangabey

The agile mangabey is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo.

Until 1978, it was considered a subspecies of the Tana River mangabey. More recently, the golden-bellied mangabey  has been considered a separate species instead of a subspecies of the agile mangabey.

Similar to other mangabeys, they are active during the day. Although generally tree-living, they do spend a significant portion of their time (12–22%) on the ground, especially during the dry season. It is often heard first, and males have a loud, species-specific call that is believed to be used to space themselves out – in a similar way that wolves operate with howls. Other calls are also used to maintain group cohesion and warn of predators. Group size can be as high as 18 members, led by a single dominant male. Group meetings can be friendly and may involve exchange of members.

Adult males not in groups often travel singly.

Fruit makes up a major portion of the agile mangabey diet. They are known to eat at least 42 different species of fruit. Their tooth structure and powerful jaws allows them to open tough pods and fruits that many other monkeys can not access. Agile mangabeys eat from a number of dominant swamp-forest trees, including Irvingia, Sugar plums when they are fruiting. They also eat fresh leaf shoots from Raffia palm when fruits are scarce. Grass and mushrooms, Invertebrates, bird’s eggs and some vertebrate prey, such as rodents.

As we find links, to help you book to see this species, the links will be added at the bottom of the page.

The primates are in some ways one of the most successful families. It is true that many are now endangered, however, unfortunately, that is as a result of the run-away success of the most successful member of the primate family us! Having left the rainforests behind, we have been reducing their coverage dramatically over the last few centuries. 

The sad thing, is that while we have pushed many of our closest cousins towards extinction, the loss of forests may well cost us dearly in the future as well. As a species, we need to pull together to meet this challenge. in order to jump to the various families, click on the family of interest above – though all can also be reached by scrolling down.

Great Apes

Chimpanzee
Boonobo
Sumatran Orangutan
Borneon Orangutan
Tapunali Orangutan
Humans on the beach
Eastern Lowland gorilla
Mountain Gorilla
Western lowland gorilla
Cross river gorilla

Great ape Family split is thought to have split from its nearest relative – the gibbon family, around 17 million years ago.

4 million years later the Orangutan family split from the gorilla line and the human/chimp line.

3 million years after this (so around 10 million years ago) the gorilla family split from the Homo (humans) and Pan

Finally the human line (homo) split from the Pan line 5-6 million years ago.

It should be noted, that chimpanzees and Bonobos split from a common ancestor just 1.8 million years ago. This occurred as the two populations ceased to be able to have contact with each other – the Congo rive formed between 1.5 and 2 million years ago.

It should be noted that while I have grouped eastern western and skywalker gibbon together, there is some contention that the skywalker gibbon should be in its own genus, having diverged around half a million years aog

Gibbons

siamang gibbon genus Symphalangus
hookock gibbon (Eastern, Western and Skywalker) Genus Hoolock
genus Normascus (crested gibbon)
Agile gibbon

Genus Nomascus

This family is the Genus: Nomascus or crested gibbon.

The last Genus of gibbons is Hylobates: dwarf gibbons.

Allens swamp monkey

Allens swamp monkey

Given where they choose to live, they are currently listed as least concern, however, the population is declining, as a result of a mixture of hunting for the bushmeat trade, and habitat loss. While it is also hunted by raptors, snakes and bonobos, this hunting relies on the availability of the monkey, which means that as populations decrease there is less hunting, unfortunately we humans have overcome this natural method to stop extinction.

Below is a list of articles on this site which have been published on this site, and below this is a camera trap video of this monkey in the wild. Below both of these, we will add any links to places where this species can be seen in the wild, which will help the survival of this species.

Andes Cloud forest – Ecuador

Andes cloud forest of Ecuador

The Andes cloud forest fill a large part of the Ecuadorian highlands.

 

Although very rich in flora and fauna, few large mammals are found in the Andean Cloud forests, including the Yungas and parts of the Choco exceptions being the threatened mountain tapir, spectacled bear and yellow-tailed woolly monkey.

Ecuador has a national park called

Sangay national park. click here for our listing of it

    A fascination reserve with a wide range of wildlife, this is a place well worth a visit. With a variety of habitats, the range of wildlife that can be seen is not usually available in one reserve anywhere else.

     The national park is known for its wildlife. The government of Senegal estimates the park contains 20 species of amphibians, 60 species of fish, 38 species of reptiles (of which four are tortoises). There are some 80 mammal species. These included (as of 2005) an estimated 11000 buffaloes, 6000 hippopotamuses, 400 western giant eland, 50 elephants, 120 lions, 150 chimpanzees (It is inhabited by a banded forest in the park (Lower Rim) and Mount Assirik. (north-western limit line where chimps are distributed.)), 3000 waterbuck (Kobus ellipsiprymnus), 2000 common duiker (Sylvicapra grimmia), an unknown number of red colobus (Colobus badius rufomitratus) and a few rare African leopards and West African wild dogs (Lycaon pictus manguensis), although this canid was thought to be wiped out throughout the rest of the country.[4]

     

    Other mammals include roan antelope, Guinea baboon, green monkey, patas monkey, warthog.

     

    Around 330 species of birds have been sighted in the park, notably the Arabian bustard, black crowned crane, Abyssinian ground hornbill (Bucorvus abyssinicus), martial eagle, bateleur (Terathopius ecaudatus), and white-faced duck (Dendrocygna viduata).

     

    There are also reptiles such as three species of crocodiles, four species of tortoises

    Bottlenose dolphin, Sea green turtle, Caribbean manatee, Central American Tapir, Forest condor or real condor, Jaguar, Howling monkey, Ocelote in Sian Ka’an, Western manatees can all be found in this reserve. 

     

    The reserve is made up of tropical forests, mangroves, marshes and a large area of ocean.  The reserve’s name can be translated as gate of heaven. 

     

    The reserve covers over 5000 Square km, Part of which is land and the rest is in the coral sea and includes a large area of coral reef.
