Puma Hunting Feeding and Social Organisation

This page covers the areas not covered in the other pages, namely, Puma Hunting Feeding and Social Organisation. Cats generally are opportunistic predators. This means a wide range of prey depending on season and place. Pumas will treat any animal that is vulnerable as prey. Pumas are also flexible in the selection of prey. For example, in Nevada some Pumas attacked wild horses. Flexibility may in part be due to necessity because of prey reduction of an animal species (due to human activity). Pumas can also kill to create a surplus; killing many more animals than required. This probably does them no good in respect of retaliatory attacks by people! It usually occurs with sheep and might be because the panicked movement of sheep, when one is attacked, triggers the puma’s hunting instinct to attack again (moral: when people are fearful of being attacked they should not panic and run but face down and see off the puma).

Puma Hunting Feeding and Social Organisation – Method of Hunting & Success

The puma stalks and closes in on prey relying on cover such as grass and bushes. The attack might start from above at about 2.5 – 10 metres from the prey. Prey in open territory with little cover is much safer from attack. When attacking prey the puma will usually catch the prey on the side or rear and grab with the front claws. For larger prey, when it is brought down the puma kills with a suffocating bite to the throat or neck, and with a bite to the back of the neck for smaller prey such as rodents and squirrels. If a puma becomes disabled through injury in an attack it could mean the end of its life so a degree of caution prevails. Pumas get hurt in attacks on large prey and killed sometimes by, for example, falling off cliff edges or trampling. In a study of all naturally occurring puma deaths, 27% related to prey attack injuries .

The killed prey is dragged to a more secure site and hidden with leaves, grass etc. (if planning to return to the carcass). Pumas are strong and are impressive in this task. Pumas remain close to the kill. Pumas shot in California were found to have full stomachs containing 2.2 to 3.6 kg of meat. The kill is sometimes scavenged. The scavengers are sometimes killed by the Puma. On occasions, females share the male’s kill and vice-versa when they are courting.

Estimates of kill rates are: one adult deer every 8-16 days for a single puma rising to one every 3 days for a female and young. Success rates are uncertain but research suggests: 82% success rate on deer in California. While in Argentina a 10% success rate was assessed in respect of visachas (a rodent in the chinchilla family which use alarm calls and live in burrows).Research suggests that in many places the puma has little effect on prey populations (people are by far the biggest factor), while on other areas prey was decreased. The research is inconclusive it would seem.

Puma Hunting Feeding and Social Organisation – What it Hunts

This varies with availability and depends in part on where the puma is. Here is a table:

Country – PlacePrey2
Most of North AmericaDeer 60-80% of diet (average weight 39-48 kg) – fawns/calves
Central & South AmericaSmall & medium sized mammals: hares, armadillos, viscachas for example.
MexicoWhite tailed deer
Venezuela (Ilanos)For example: juvenile collared peccary (see picture below). Average weight: 8.4 kg
British Columbiabighorn sheep rams
Alberta, Canadamale pumas: Moose calves (89% of diet). Female pumas: elk & deer
Southern Chilewinter/spring: young female guanacos.

Puma Hunting Feeding and Social Organisation – Social Organisation

Most cats in the wild live alone and the puma is no different. Male and female come together for mating and the female raises the young. However, home ranges do overlap and pumas have various methods of communication including their voice to retain their territory and to notify of their presence. On the linked page, I cover the range of mountain lion sounds. Other forms of communication are:

  • scent deposits (feces and urine but pumas don’t spray like other felids)
  • scrapes
  • fecal mounds (buried feces)
  • scratches on the ground

Females are less adventurous when establishing a home range. Sometimes it is close to their natal range (where they were born and their mother’s range). Females usually breed only when settled. Males travel far and are sometimes killed by resident males protecting their range or by people hunting. The male’s life in respect of range is more problematic and transient and the establishing of a home territory fraught with difficulty and danger.

People killing pumas through hunting greatly disrupts the stability and balance of the home range structure, as can be expected. And sport hunting is a major reason for puma deaths in many areas of western USA (20-50% of all deaths in Arizona, Colorado, Nevada, Montana and Texas). The sport hunting of resident females is the worse kind of death in respect of puma population. Do sport hunters recognise this and take steps to avoid it?

Understandably, prey density impacts on the size of the home range. Lots of prey equates to a smaller range and vice-versa.

PlaceHome Range Size3
Southeastern Briitish ColumbiaFemale: 55 km². Male: 151 km²
Southern UtahFemale: 685 km². Male: 826 km²

For the female the most important factor in suitability of the home range is availability of prey (to feed the young), while for males it is availability of females! Densities of adult puma per km² are as follows:

Utah, USA0.37 to 0.5 per 100 km² – note large puma ranges above.
North AmericaDensities of more than 4 per 100 km² are uncommon it seems. In winter it can be 7-8 per 100 km².

Puma Hunting Feeding and Social Organisation Sources: The major source of the information on this page is Wild Cats of the World by Mel and Fiona Sunquist – a fine and dependable book and highly recommended, buy it! The information here should therefore be accurate. If you want to see the references to their work (which are extensive) you’ll have to buy it or you may see some here: Google Books. I also use IUCN Red List of Threatened SpeciesTM (which, incidentally, also sometimes relies on this book).
