Hunting success rates: how predators compare

It’s tough being a predator – for many species, most pursuits end in failure, while smaller hunters risk losing their hard-won meals to bigger beasts. But who’s top dog and who has to work hardest to get a meal?

Cheetahs are the third most successful predators in our round-up below. But who's the top cat – or dog?

 

10 Tigers

Based on observations made in Kanha National Park in India, US field biologist George Schaller reckoned tigers were successful only 5 per cent of the time, while tiger conservationist Valmik Thapar estimates 10 per cent. But studies of Amur tigers in Russia’s Far East, reconstructing predation events from tracks in the snow, give kill rates of a 38 per cent when hunting red deer to 54 per cent for wild boar.

9 Polar bears

Polar bears mainly hunt either by ambushing seals in their snow lairs or when they come up to their breathing holes, or by stalking seals on sea ice – in both cases, research has shown that their odds of success are 10 per cent. Some individuals on Svalbard have been observed successfully hunting reindeer and – elsewhere – killing beluga whales that must surface through a small hole in the ice in order to breathe.

8 Wolves

In 14 separate studies of wolf hunts, the average kill rate for this species was 14 per cent, but there is much variation within this. Wolves hunting moose on Isle Royale (in Lake Superior in the US) were found to be successful just 6 per cent of the time, while wolves chasing white-tailed deer in Minnesota made a kill about 20 per cent of the time.

7 Lions

The hunting success rate of lions is strongly dependent on the number involved – a single lion hunting in daylight has a success rate of 17-19 per cent, but this increases for those hunting as a group to 30 per cent. Of 1,300 hunts observed in the Serengeti, nearly half involved only one animal, 20 per cent involved two and the rest a group of (normally) between three and eight individuals.

6 Domestic cats

A recent study of feral domestic cats, carried out by scientists in northern Australia, found they were made a kill in 32 out of 101 hunting attempts – a success rate of 32 per cent. This kill rate soared when they were hunting in open habitat to 70 per cent. Only 28 per cent of kills were actually eaten.

5 Leopards

Studies carried out on leopards have revealed wide-ranging success rates, varying from 38 per cent for individuals in north-east Namibia to 14 per cent in the Kalahari. A female with cubs has been shown to have a kill rate of 28 per cent, while a lone male can only achieve one of 14 per cent!

4 Peregrine falcons

Scientists observing peregrine falcons predating dunlin in Washington State in the USA recorded a success rate of 47 per cent with “perch-to-perch” hunting flights that involved one or more capture attempts. Stoops, where the falcons drop from a height (normally about 50-80m, but in some cases up to 1,000m), were used in 65 per cent of flights.

3 Cheetahs

A study from the Serengeti in 2012 observed 192 cheetah pursuits, of which 114 ended in a kill – a success rate of 58 per cent. In order to stop larger carnivores from stealing their hard-earned meals, they move them to more secluded, shadier spots - even so, research suggests they are ousted 10 per cent of the time.

2 Black-footed cats

Black-footed cats are astonishingly active and successful nocturnal hunters – one scientist’s observations show they make a hunting attempt every 30 minutes, and are successful 60 per cent of the time. They eat a wide variety of prey, from gerbils and shrews to small birds and insects, and make 10-14 kills every night.

1 African wild dogs

The lean frames and endearingly large ears of African wild dogs are deceptive – they are one of the most successful predators anywhere, with a kill rate per chase of more than 85 per cent. That’s not the whole story, however – they may lose half of their kills, ranging from small impalas to wildebeest 10 times their weight, to other carnivores such as hyenas and lions.
