In Search of a Mate


Shy Boy bites the back of TiBo's neck, 36 months old, in her first ever mating

Hello Friends 

I once had a fascinating conversation with Jane Fonda, concerning  "teen pregnancy" in America. 

The theme of Jane's concern was that although American teenagers viewed several hours of TV a day, where sex and violence was graphically shown, the teenagers remained dangerously ignorant when it came to sex. 

In fact even today, 820 000 teenagers in die USA become pregnant each year. In South Africa around 70 000 girls younger than 18 fall pregnant every year.

It's a fascinating time at Tiger Canyons because Tigress Julie's three teenage daughters, Tiger Bomb (TiBo), Indira and Ussuri are all coming into estrus for the first time. 

Tigress Julie, their mother, has been physically aggressive to them for some months, forcing them to disperse out and find territories of their own. 

Nature provides an ingenious system to maintain genetic diversity. All the young tigresses come into estrus at the same time. 

Now the dominant male "Shy Boy" who has access to all three females, can only mate with one of the daughters, because he must commit a full 4 days to the mating with one female. 

While "Shy Boy" mates 150 times over 4 days with "TiBo", his brother "Tiger Boy" has access to "Indira" and another male "Sariska" gets  to mate with  "Ussuri". 

Under this system, the gene lines are kept diverse. If the tigresses estrus was not synchronized, then "Shy Boy" could cover all three females and then all the cubs would have one father instead of three. 

It is fascinating to watch the young tigresses advertise their estrus. They perch on high rocks where they vocalize and leave chemical messages to advertise their condition. 


Ussuri, 36 months old, sits high on the rocks in a visual display to the male tigers

Compare this to young girls sending scripted messages to prospective boyfriends. On Facebook they can put pictures of themselves and give details of their preferences. The Blackberry revolutionized courting behaviour because through the BBM system, they can talk for free. I have seen teenage boys actively swapping and trading BBM numbers of girls to add to their Blackberry list. The prettier the girl, the higher the price her BBM and telephone number will be. 

One teacher at a prominent girls boarding school, told me that the rule was that all cell phones should be handed in during the week. The girls would beat the system by buying two cell phones. One would be handed in and using the second, they would during class send messages to boys at the nearby boys school. The girls became so efficient, that they could send a message by holding the cell phone under the desk and sending the message blind. 

Clearly the urge to find a mate is a powerful force in humans, tigers and indeed all successful species. 

It is well known that pheromones play a huge role in the connection of prospective mates. Young ladies have learnt to use perfumes to enhance these pheromones. The young tigresses roll in certain Karoo herbs to make themselves socially more attractive. 

Therefore in a search for a mate, the young tigresses have sent chemical message through their territorial marking fluid. The young tigresses have become very visual by perching on rocks and  have called for a mate with vocal communication. 


By spraying on prominent trees and rocks with marking fluid, the young tigresses  advertise their estral condition
The young ladies have used cell phones, facebook etc. to communicate to prospective mates. By using make-up and perfume they have made themselves more beautiful and socially more attractive. The tactics used by teenage girls and young tigresses are virtually the same. 

A male tiger pulls a Flehmen Face. By sucking in the scent and passing it through the Organ of Jacobsen in the roof of his mouth, he determines whether the tigress is ready for mating

By following the chemical trail of the lioness, the male lion locates her and determines whether she is ready for mating

It is in the copulation that the tigers and humans differ. 

In Tigress Julie's last litter, she copulated 150 times to produce 5 cubs. This means for every cub, she must copulate 30 times. This is an enormous expenditure of energy and time.

For human beings, just one copulation at the right time can result in pregnancy. The energy expended in copulation for human beings is far less than for tigers.

 
The copulation can be painful for the tigress so she aggressively orders the male to dismount.

The reward for multi copulation in tigers, is 4 or 5 cubs in a litter, whereas human's rarely produce more than one offspring. 

Tigresses can produce offspring in their 4th year, whereas human beings must wait for 12 to 13 years before producing young. 


After mating, TiBo rolls on her back to allow the sperm to travel.

Therefore one may ask which is the better system? Human beings now number 7 billion, so in theory theirs is the better system.

However, one must ask at what environmental cost has their been to achieve this number? How many species have humans swept aside to became the "dominant species" on planet earth? 

The reproduction of the tiger is a highly successful system, but it is being out competed by human beings. 

If the number of 1 tiger lost per day in the wild is correct, then the wild tiger will be gone in 4 to 5 years. 

Then all that will remain is 50,000 tigers in zoos, circuses and private collections, an indictment against the human species, if ever I saw one.
