Behavior of Llamas

Behavior


A pack llama in the Rocky Mountain National Park Llamas which are well-socialized and trained to halter and lead after weaning are very friendly and pleasant to be around. They are extremely curious and most will approach people easily. However, llamas that are bottle-fed or over-socialised and over-handled as youngsters will become extremely difficult to handle when mature, when they will begin to treat humans as they treat each other, which is characterized by bouts of spitting, kicking and neck wrestling. Anyone having to bottle-feed a cria should keep contact to a minimum and stop as soon as possible.



When correctly reared spitting at a human is a rare thing. Llamas are very social herd animals, however, and do sometimes spit at each other as a way of disciplining lower-ranked llamas in the herd. A llama's social rank in a herd is never static. They can always move up or down in the social ladder by picking small fights. This is usually done between males to see who will become alpha. Their fights are visually dramatic with spitting, ramming each other with their chests, neck wrestling and kicking, mainly to knock the other off balance. The females are usually only seen spitting as a means of controlling other herd members.



While the social structure might always be changing, they live as a family and they do take care of each other. If one notices a strange noise or feels threatened, a warning bray is sent out and all others come to alert. They will often hum to each other as a form of communication.



The sound of the llama making groaning noises or going "mwa" is often a sign of fear or anger. If a llama is agitated, it will lay its ears back. One may determine how agitated the llama is by the materials in the spit. The more irritated the llama is, the further back into each of the three stomach compartments it will try to draw materials from for its spit.



An "orgle" is the mating sound of a llama or alpaca, made by the sexually aroused male. The sound is reminiscent of gargling, but with a more forceful, buzzing edge.

Reproduction In Llamas

Reproduction

Llamas have an unusual reproductive cycle for a large animal. Female llamas are induced ovulators. Through the act of mating, the female releases an egg and is often fertilized on the first attempt. Female llamas do not go into "heat" or have an estrus cycle.


Like humans, llama males and females mature sexually at different rates. Females reach puberty at approximately 12 months. However, males do not become sexually mature until approximately 3 years.



Mating

Llamas mate with the female in a kush (lying down) position, which is fairly unusual in a large animal. They mate for an extended period of time (20–45 minutes), also unusual in a large animal.



Gestation

The gestation period of a llama is 11½ months (350 days). Dams (female llamas) do not lick off their babies, as they have an attached tongue which does not reach outside of the mouth more than half an inch. Rather, they will nuzzle and hum to their newborns.



Crias

A cria (from Spanish, pronounced cree-ah, meaning "baby") is the name for a baby llama (also alpaca, vicuña, or guanaco). Crias are typically born with all the females of the herd gathering around, in an attempt to protect against the male llamas and potential predators.

Llamas give birth standing. Birth is usually quick and problem free, over in less than 30 minutes. Most births take place between 8 a.m. and noon, during the warmer daylight hours. This may increase cria survival by reducing fatalities due to hypothermia during cold Andean nights.

While unproven, it is speculated that this birthing pattern is a continuation of the birthing patterns observed in the wild. Crias are up and standing, walking and attempting to nurse within the first hour after birth.

 Crias are partially fed with llama milk that is lower in fat and salt and higher in phosphorus and calcium than cow or goat milk. A female llama will only produce about 60 ml (2.1 imp fl oz) of milk at a time when she gives milk. For this reason, the cria must suckle frequently to receive the nutrients it requires.

Number of Llamas

As of 2007, there were over 7 million llamas and alpacas in South America and, due to importation from South America in the late 20th century, there are now over 158,000 llamas and 100,000 alpacas in the US and Canada.
