MAN
IN MONKEY BUSINESS
A Senior Lecturer and a Master’s student at Peradeniya
University come up with an innovative programme to curb the problem
of rampaging monkeys. Kumudini Hettiarachchi reports
He
sits chin in palm staring out, eyes darting here and there. Get
close and the result is instantaneous. A vicious baring of sharp
teeth. What this close simian cousin of humans does not know is
that he is a trailblazer in research studies done in Sri Lanka.
The
pioneer behind the monkey study is Dr. Ashoka Dangolla, Senior Lecturer
of the Faculty of Veterinary Medicine and Animal Science, Peradeniya
University, with the spadework being handled by Maheshika Rupasinghe,
37, an M.Sc. student whose research is on monkeys.
And
Maheshika has spent many an hour gazing at and taking copious notes
on eight monkeys (Toque macaques of the genus Macaca sinica) in
a major effort to bring about a solution to a perennial problem
faced by men, women and children living across Sri Lanka from Kandy
to Anuradhapura, from Nawalapitiya to Hambantota and from Pelawatte
to Vavuniya.
Monkey
invasions into homes and property all over the country have left
people in despair with some even taking drastic action on their
own to shoot, poison or beat the monkeys.
“Petitions
have been sent to high officials and institutions, with people begging
and pleading that something be done to curb the monkey menace,”
says Maheshika, explaining that three months ago Dr. Dangolla decided
to do something about this grave issue. That is how it all started.
Dr.
Dangolla has now come up with two solutions to this two pronged
problem. The monkeys who are a nuisance come from two groups –
the wild troops which swing in, cause damage, bite people and swing
out, targeting areas where they find the food they relish mainly
in the form of ripe fruit and the lone or rogue monkey which has
either been rejected by its troop or tamed by humans as a pet and
then abandoned due to various reasons.
“Monkeys
reproduce fast and have a baby per year. We have now worked out
a procedure for sterilization, both hysterectomies for females and
castrations for males that can be carried out in the wild itself,”
says Maheshika.
Dr.
Dangolla has designed a special trapping cage that can be kept in
the wild filled with fruits. When some monkeys are caught in it
they can be sterilized and later freed. Explaining how they came
about this solution which they had tried out on the loners first,
Maheshika says two monkeys of a wild troop haunting the university
premises got caught in the cage set for other research purposes.
The troop attacked the cage and managed to free one while the leader
was unable to get out as the door got shut in the melee.
A team
headed by Dr. Dangolla took their chance and castrated the male.
“The operation is only about 15-20 minutes. We kept the leader
in the cage to check out the after-effects. Everything was fine.
The leader was released three days later, and the troop welcomed
him with open arms,” says Maheshika.
Sterilization
is a long term solution but there will also be short term results,
assures Maheshika, lamenting that they need funds to build the special
trap-cages. To the query whether monkeys will become extinct, Maheshika
shakes her head with a resounding “No”. “Only
a few from a troop and not the whole troop will get caught so there
is no such danger,” she says.
The
other revolutionary development in this groundbreaking research
by Dr. Dangolla is the formation of an “artificial”
troop with monkeys drawn from different areas and different backgrounds.
In the past two years, whenever he heard of a rogue or lone monkey
disturbing the peace, he and his team had darted the alleged offender
with anaesthesia and brought it back to the university.
There
is a motley group of eight such monkeys – five males and three
females -- collected over a period of time. (See box for two of
their life stories).
Most of them had been tamed by humans but thrown out of home or
escaped on their own. Now not only have they been given the rabies
shots -- because many are the handlers and feeders who have come
out worse for wear in their dealings with these animals having to
get sutures -- but the monkeys have also been sterilized. “See
how they are living together without any problem,” points
out Maheshika leading us to a large specially-designed cage complex
near the faculty.
While
all of them look alike to our inexperienced eye, Maheshika knows
them individually for she has spent hours studying their behavioural
patterns of which there are 23 including self-grooming, social grooming,
aggression, play fighting and also fighting.
“That
is No 1,” says Maheshika and there sits the leader of the
“artificial” troop, turning his back on the others looking
surly and belligerent. In the other corner is No. 4 sprawled on
the floor, tummy up, legs and hands stretched out, utterly relaxed
and very much the Casanova, while two others are meticulously and
nimbly parting his fur and looking for fleas.
After
they were collected, a decision was taken to gradually introduce
the males to each other, with the sliding doors and contours of
the cage being designed with this in mind. “The aim was to
see whether these monkeys would establish their own hierarchical
order and select their leader though they were not linked before,
forming an artificial troop,” says Maheshika.
The
task was a difficult one – there were five grown-up males
with their individual eccentricities and foibles. The researchers
would let one into a corridor and then gradually release another.
The battle for leadership was on. Within a few weeks, there were
two contenders for the top post – No. 1 and No. 4. The fighting
was bitter, leading to treatment, patching up and a near-amputation.
“In desperation we played the final card – that of providing
partners for them.”
Two
of the three females were let loose among the two ferocious males
engaged in a do or die fight for dominance. “It was amazing,”
smiles Maheshika. The result was incredible – both were felled
by the charms of the fairer sex. No. 4 also gracefully left the
ring, saluting No. 1. “There was only play-fighting between
them thereafter,” says Maheshika, making us recall how “human”
they seemed to be. From that day No. 1 was the leader.
Now
the final step is awaited – the release of this artificial
troop to the wilds. “We are scouting for a location. The ideal
place will be a small, lush island in a wewa with plenty of monkey
food. We’d like to monitor them but radio collars are very
expensive,” adds Maheshika.
Beleaguered
people can now let out a sigh of relief – for there seems
to be an answer to the monkey menace, an answer that is in keeping
with animal rights and is environmentally and socially friendly.
The
tricky one and the sadistic one
No. 1 had been tamed and most likely abandoned, when he rebelled.
Hitching a ride on a pony from an army camp near his haunts, he
would jump off at the “thun bar” junction with three
liquor bars. There he would drink to his hearts content, encouraged
by the people who frequented the bars who offered him “shots”.
After
that it was monkey tricks for him but terror for the people living
in the area. He would rampage through the streets attacking people
and damaging homes and property.
Meanwhile,
No. 5 had a sadistic streak. Believed to have been tamed and then
abandoned, he had joined a pack of stray dogs ruling the land he
surveyed and instilling fear in women. Swaggering up to any woman
passer-by, he would nonchalantly tug her skirt or cloth up. When
the woman screamed, she had to face his wrath, a quick attack –
a bite or a scratch here or there. |
