Reproductive Behavior

Tiger subspecies are spread out over differing regions and climates, which effects patterns of reproduction. Thus, the following is an outline of the basic characteristics of reproductive behavior found across tiger subspecies, but specific details may vary between subspecies.  Female tigers reach sexual maturity around 3-4 years of age, while male tigers do not reach this point until they are 4-5.  Once reaching maturity, female tigers signal that they are in heat (which occurs most frequently during the cooler months) in a variety of ways, including secreting a specific scent and attracting attention through roaring and other noises.  These behaviors are meant to attract potential mates, who approach the tigress warily.  Tigers are solitary creatures and therefore require a slower mating process while they ascertain that no harm will befall them.  In some instances, tigers will fight over a mate both have claimed.  These fights continue until one tiger gives up or dies.  Tigers do not mate for life and take many different partners.  An interesting fact about female tigers is that they do not release an egg to be fertilized until mating has already begun.  



Once a female is pregnant, the male tiger is out of the picture and the tigress must take sole responsibility for her young.  The female tiger's gestation period is four months and the general size of the litter is approximately 3 to 4 cubs.  Female tigers care for their cubs until they are around 2 years old.  Because tiger cubs stay with their mothers for so long, there is usually a 2 year gap between births.

Zoo Visit

This past weekend I visited the San Diego Zoo and spent some time at the tiger exhibit.  Below is a picture I took of the tiger, who was surprisingly active during my visit.  In my previous experience, tigers at zoos and wild animal parks have always been fairly reclusive and difficult to observe.  This time, however, the tiger was trotting around and sat down right in front of us to chew a large bone.

It is my opinion that the San Diego Zoo does it's best to provide adequate living conditions for its animals, but any kind of captivity for wild animals seems less than ideal.  The exhibit for the tiger hardly seems spacious enough to allow for such a large, powerful animal to get a sufficient amount of exercise and exploration.  However, I understand the work many zoos do to help protect endangered species, which include all subspecies of tiger.  I trust that those who work at the zoo and design exhibits take into account what is in the best interest of the animals and hope that every animal in captivity is treated with respect and allowed the chance to live as naturally as possible.

Welcome!

On the off chance that anyone outside of Animal Psych reads this blog, let me explain what'll be going on here.  If the title wasn't clear enough, this blog's aim is to inform the reader on many different aspects of the tiger species. They've always been my favorite zoo animal, so I'm taking this opportunity to learn something about these animals beyond how cute they are.  I can't pretend that I know much yet, but we're going to learn together. To start us off, take a look at a few pictures to familiarize yourself with our topic of interest.  Next week I'll be back to dive into a little history of these great cats. Thanks for reading!
