Warthogs breed in the summer rainy seasons in the southern parts of Africa. They could have between 1 to 8 pigets( average being 2-3 piglets) weighing 450-900g each. They are born after a gestation period of 160-170 days. Each piglet is alocated to its own teat and is not allowed to suckle from another.

Noticed on my last visit, no little warthog.
In terms of maximising on droppings, hares might be the most efficient. They use their droppings as vitamin pills. The most cost effective way of recycling nutrition.

I was told by a ranger in Kruger that warthogs drastically reduce reproduction in times of drought, that's apparently the reason for so few babies being spotted in the last few years.

DID YOU KNOW??
That warthogs were named because of there wart-like markings on there face, there are two of these 'warts' just under there eyes. The 'warts' are used to mark territory, by wiping them on vegitation and other objects in there home range.

I have also never seen the park so dry.


Ar'n't warthog also a favourite food of leopard? I wonder if they are feeling the decline in their food choice?

This weather is freaky, I've never been so cold in October :shock:

It would be good to hear from people experienced in patterns in the park.
One of our rangers told us that the predators do well during early drought, as the prey were often weakened by lack of food and water.
This was my worst experience of the park, but maybe I have been lucky in the past.

That is a useful picture Jazil. That is a female warthog as males have two pairs of 'warts' on the sides of the head compared to a female's one pair, which is relatively small (as in picture).

The picture is useful because you can see the dark discolouration or 'tears' running down from the eye.

Warthogs have two major types of facial glands, the tusk gland located in the upper lid behind the tusks and the preorbital gland.
Which is found near the inside of the eyes (as in the picture).

The tusk gland secretion is found to be involved in warthog courtship and territory marking with the preorbital gland. Another function of the tusk gland includes communicating status.
This is particularly key to warthogs since males are solitary and live with one or more females in which their home ranges overlap.

The height of scent and tusk scrape marks could provide clues to the largest most dominant males in the area.

Rubbing together of preorbital glands is a means of communication between individuals and important in the courtship display between prospective mates.

The location of this gland is not near the enlarged warts and the warts are dermal and do not contain glands. Its believed that because males have larger and more numerous growths, that they evolved to protect the eyes and jaw from sparring contests with other males during dominance battles and practice.
Contests of strength are usually tusk-to-tusk and forehead-to-forehead pushing matches.
Low sideways blows are wicked and violent fights are bloody, though it usually doesn't come down to that. The mouth is usually kept closed during ritualized hierarchy sparring, with the upper and lower tusks clamped together.
Warts offer protection from this potential damage.

Warthogs have no sweat glands and like elephants are usually left or right 'handed/tusked' and use one more than the other wearing it down.

This is a picture of the same warthog, you can see that she is pregnant. Her nipples are long and extended.

Thank you for the info re the "two pairs of warts" for the males.

Is this bacteria to help them digest their food?


Translation below

Alo amigos

Eu estou feliz por ter tido temp escrever vos de novo no forum. E estou feliz porque o Jumbo tem muito tempo de traduzir.

Na vizita que fezemos em Setembro em Kruger eu e Jumbo vimos o javalim na bela da Estrada a alimentar-se de merda do elefante,
Isto era antes de chuver e o arbusto estava muito seco.

eu queria saber se e de costume alimento ou porque arbusto estava seco e nao tinha nada para comer. Ou porque precisava de algumas baterias?


Hallo friends

I am happy to have time to write something new on the forum. I am also happy Jumbo now has time to translate for me.

On my last visit to Kruger in September, Jumbo and me saw a warthog at the edge of the road that was eating elephant dung. This was before the rain and the bush was very dry.

I want to know if this is normal food for them or did he eat it because the bush was dry and he had nothing else to eat? Or is it because he needed some bacteria?

Or is it that he is after the nuts in the dung? Ellies hardly digest their food, so most comes out unchanged, especially the nuts.

We saw lots of warthog families with young ones quite small in December last year. First time I've ever seen a baby warthog - even cuter than their parents. 8)

Interesting information about the difference in the number of "warts" between the different sexes.
Below then photos of males.
The lone one must be an old one when you look at the size of the "warts" compared to those of the 2 on the other photo.
Any body knows if the size of the "warts" are indicative of age?
