Monk Saki
Pithecia monachus

Though the quality is not very good I wanted to share this monkey with you as it will be the first presentation of this species in TrekNature and also they are very difficult to view in the wild, due to shyness and a very high habitat.

Thanks for looking and have a nice weekend

*Geographic Range
Also known as Pithecia hirsuta, Pithecia monachus can be found in northwestern Brazil, Colombia, Ecuador and Peru (Nowak, 1999). Members of this species occur in the Colombian trapezius north of the Amazon, and extend from north of the Putumayo River to the southern bank of the Yari, Caqueta and Orinoco rivers. The range of Pithecia monachus is limited to the upper elevations of well-developed rain forests of these regions (Hernandez-Camacho and Cooper, 1976). (Hernandez-Camacho and Cooper, 1976; Nowak, 1999)

Arboreal, high canopy dwellers. They are very nervous around humans and disturbance, thus very little data has surfaced on the lifestyle of P. monacha. However, scientists agree that the tallest trees available (from 10-35 meters tall) are the habitat of choice for these animals, and in most instances they are the sole primate inhabiting this niche. (Moynihan, 1976)

Physical Description
Sakis are characterized by their small size of 30-50 cm and very heavy, thick and nonprehensile tail which adds 25-55 cm to their body length (Nowak, 1999). The face of the monk saki is partly bald but bearded with a hood of curly black hair covering the forehead. The nostrils are laterally positioned on the face (Flannery 2004). Sakis are generally black, but their hands and feet are light in color.

The skull morphology is distinctive: the orbits are separated from the brain case by a frontal depression. The incisors are forward-facing, long canines are present and used to break the hard skin of fruits. They have quadritubercular molars with deep basins (Seth & Seth, 1986).

The hands are similar to those of Aloutta spp. in that they exhibit a split between the second and third digits (Moynihan, 1976). Each digit has a nail, and the front limbs are shaped for gripping branches after a leap. The hind legs are modified for fast and far leaping. Vision is stereoscopic for an arboreal habitat. (Flannery, 2004; Moynihan, 1976; Nowak, 1999; Seth and Seth, 1986)

Mass: 1 to 2 kg
(2.2 to 4.4 lbs)
Length: 30 to 50 cm
(11.81 to 19.69 in)

Adult, monogamous pairs breed for life.
Number of offspring: 1 (average)
Gestation period: 170 days (average)
Birth Mass: 120.67 g (average)
(4.25 oz)

Territory Size: 0.33 to 0.50 km^2
All species of Pithecia are diurnal. The monk sakis are quadrupedal leapers. They are skittish and shy. Family groups are nuclear families consisting of a monogamous pair with its offspring. These families raise offspring in defended territories, similar to gibbons in the genus Hylobates. A peculiar behavior is observed at night when several families sleep in the same tree. The adults recognize their mate by highly specialized vocalizations; acoustic signals including squeaks, whistles and trills are used for low intensity aggression. Barks and grunts constitute a higher level of aggression, and finally, roars are the most extreme aggressive vocalizations. The monk sakis practice extensive allogrooming as a general social behavior which is nonsexual in orientation or motivation. (Hernandez-Camacho and Cooper, 1976; Moynihan, 1976)

Very little research has been done on Pithecia monacha, perhaps for two reasons: they do not survive well in captivity, and are very difficult to view in the wild, due to shyness and a very high habitat.

Merhaba Selen,
congratulazioni per questa prima su TN, nonostante le varie difficoltà hai fatto una eccellente cattura, il collage mostra splendidamente le caratteristiche di questa strana e spettacolare scimmia.

Hi Selen,
Very good presentation of this Monk Saki Monkey showing well how it moves around its natural habitat. Sometimes one still picture does not give fair impression of a wild creature. Very good result in hard conditions.

Hello Selen
This is fantastic! A new species for us lovers of animals and Nature photography! I had never seen this strange and curious monkey and I am delighted with this presentation. To capture a creature at a distance and against the sky... you know it will be dark, but you did a great job here for us to see the details.
Congratulations and thank you very much for sharing.
Best regards

Merhaba Selen Hanım,
Çok eneteresan bir maymun,ilk defa görüyorum.Detaylar,yüzdeki ifade ve presentasyonu
çok beğendim.
Selamlar,ellerinize sağlık!

Hi Selen,
A nice capture of this beautiful monkey. Very well composed with sharp details. Thanks a lot for sharing.

Hello Selen,
These are very difficult animals to capture, even in captivity let alone in the wild.
I have a few in my gallery, I captured a few years ago. Photographed in captivity though...
TFS a wild one:-)

A rare sight I'm sure Selen, and perfect captures, all three of them. I'm quite astonished by the sight of that tail, not like that of the usual monkey and wonder whether it is used purely for balance or does it also have a prehensile function... TFS these rare images my friend.

Dear Selen,
Excellent POV for Monk Saki from down below with details including photographer's note. TFS.

Kewl...It looks like s drunk lady threw her fur coat up in the trees..:-) I say that with tongue in cheek humour and 3 beers in my system....but I think it is a pretty important picture and now I have only short time to write..So suffice it to say....Wow! Michael Stipe, a friend, loves to say that...he even puts it in his REM lyrics...but I digress..
