Wildlife in the Masai Mara: your odds and the latest counts
Lion, elephant, buffalo and giraffe are close to certain in the Masai Mara, and most visitors see cheetah too. The numbers behind those sightings are less comfortable: the June 2024 government count found a quarter fewer large animals in the ecosystem than in 2021, and the resident cheetah population is the smallest on record.
If you only want the answer
In two or three days you will almost certainly see lion, elephant, buffalo, giraffe, hippo, zebra and spotted hyaena, and you have a good chance of cheetah and leopard. Wild dog takes luck: 7 per cent of travellers in one large sample saw one. The 2024 surveys counted about 465 lions older than a year and 2,702 elephants across the ecosystem, while resident adult cheetahs fell from 28 in 2023 to 12 in 2024.
Your odds, species by species
The bands below assume two or three nights with game drives in the reserve or a conservancy. Guaranteed means you would be unlucky to miss it, likely means most visitors see it, chance means a fair number do, and luck means a sighting worth talking about at dinner. The evidence is a mix: government and research counts for the numbers, and traveller sighting rates from Expert Africa and SafariBookings reviews for the odds, which are reports rather than systematic surveys.
Leopard is the one to read twice. It is rated likely here because 63 per cent of Expert Africa travellers in the reserve and 77 per cent in the conservancies saw one, but those are mostly stays of several nights. On a single night, treat leopard as a chance.

Counts are the June 2024 aerial total count in the National Wildlife Census 2025 Technical Report, which covers the reserve, the conservancies and wider dispersal land, so they are context rather than a headcount for the reserve. Sighting percentages are Expert Africa traveller figures for the reserve and the conservancies, read 6 Oct 2026.
Three Maras: the reserve, the Triangle and the conservancies
The wildlife figures only make sense if you keep three areas apart. The reserve east of the Mara River, with Talek, Sekenani, Musiara and the Sand River area, is run by Narok County. The Mara Triangle, the part of the reserve west of the river below the Oloololo escarpment, is managed for the county by the Mara Conservancy, a non-profit company. The conservancies on former group ranches to the north and east, Mara North, Lemek, Olare Motorogi, Naboisho, Ol Kinyei and others, lie outside the reserve boundary on community land.
The animals ignore the boundaries, and so do the government counts. The June 2024 aerial count covered about 12,540 km2: the reserve, fifteen named community areas from Loita to Siana, and part of the Mau forest. When this page gives an ecosystem figure, it is for that whole area and not for the roughly 1,500 km2 of the reserve.
Where you stay changes what you can do more than what you see. Lion density is highest in some conservancies, the hippo pools sit along the Mara River in and on the edge of the reserve, and the big river crossings happen on the Mara River inside the reserve.
How many animals are there? The 2024 census
Kenya's National Wildlife Census 2025 Technical Report holds the Mara count flown from 19 to 25 June 2024, set against the count of 6 to 10 May 2021. These are aerial total counts, which means minimum numbers with no confidence interval, and the June timing is deliberate: it counts the resident animals before the migratory herds arrive from Tanzania.
The direction is clear. The total fell from 119,371 animals to 88,856, down 26 per cent in three years, with impala, topi, Thomson's and Grant's gazelle all down by more than a third. Elephant and hartebeest were the exceptions. A study of the long run, published in the Journal of Zoology in 2011, found that almost all wildlife populations in the reserve and the surrounding ranches had fallen to a third or less of their former abundance between 1977 and 2009.

|---|---|---|---|
| Common zebra | 29,195 | 32,358 | Down 10% |

Lions: about 465, and densest in the conservancies
The Mara Predator Conservation Programme surveys lions every year from August to October across 2,713 km2: the reserve, the Triangle and fifteen conservancies. Its 2024 survey, the eleventh in a row, put the population at 465 lions older than a year, 16.5 per 100 km2, against 480 in 2023. The government census adopts the same figure. The programme prints its error bars only as a graph, so no numeric range is published.
The split by area is the useful part. The reserve east of the river held 195 lions in 2024 at 18.5 per 100 km2, the Triangle 71, down from 92 in 2023, and Mara North 50. The highest densities were in three conservancies, Lemek, Olare Motorogi and Ol Kinyei, all above 20 lions per 100 km2.
Lions here still die from poisoning. In October 2025 three young lionesses in the Triangle recovered from poisoning and were released back on the 15th, according to the Mara Conservancy's monthly report.
Cheetah: seen often, but the residents are at a record low
Most visitors see a cheetah, 78 per cent of Expert Africa travellers in the reserve and 86 per cent in the conservancies, because the short-grass plains make them easy to spot and animals from the Serengeti side pass through. The resident population tells a different story. The Mara Predator Conservation Programme counted 28 resident independent adult cheetahs in its study area in 2023 and 12 in 2024, a drop of more than half, and calls the population at an all-time low.
The programme adds that the total number of cheetahs using the Mara over a year is much higher than the resident count. The government's draft recovery plan for cheetah and wild dog puts the transboundary Mara at about 30 cheetahs in 2025, and Kenya's national estimate fell from 1,160 in 2021 to 605 in 2025, partly because of how the earlier figure was estimated. Any page calling the Mara a cheetah stronghold without a date is quoting the past.
Leopard and spotted hyaena
The only measured leopard density for the Mara comes from a camera-trap study in the Mara Triangle: 34 stations over 63 nights between April and June 2019 photographed 13 individuals across 510 km2, a density of 1.90 per 100 km2 (plus or minus 0.56). The authors, publishing in the African Journal of Ecology in 2025, call that relatively low compared with other regions. There is no reserve-wide or ecosystem leopard estimate in the national census.
So leopard is a matter of time and riverine bush. The sightings rate rises with length of stay, and the conservancies, where night drives are allowed, report the higher figure. Spotted hyaenas are the opposite problem: the census puts about 450 in the Mara, and the Mara Hyena Project, which has studied clans here since 1988, records 0.47 to 2.62 adults per km2, with the highest densities around Talek.
Elephant, buffalo, giraffe and hippo
Elephants are the one large species with a rising count: 2,493 in 2017, 2,595 in 2021 and 2,702 in June 2024 across the ecosystem. Buffalo went the other way, from 11,604 in 2021, then the largest buffalo population in Kenya at about 28 per cent of the national total, to 8,878 in 2024. Both are seen by practically every visitor.
Masai giraffe fell from 2,607 in 2017 to 2,109 in 2021 and 1,611 in 2024. The census names the Mara among the three ecosystems driving the national decline, and the Mara still holds 15.5 per cent of Kenya's Masai giraffe. Older pages quoting 2,100 to 2,600 giraffe are out of date.
Hippos are badly undercounted from the air, which is why the 2021 aerial figure of 534 is misleading. A 2018 study in Nature Communications puts more than 4,000 hippos in the Kenyan part of the Mara, spread across about 171 pools on the main river and its tributaries. Crocodiles share the same water, and the Mara Conservancy's campsite notes warn about both.
Wild dogs: gone in 1991, back since about 2001
Wild dogs disappeared from the Serengeti-Mara in 1991, after a rabies outbreak killed a Mara pack in 1989, and dogs re-established themselves naturally around 2001. Genetic work published in Conservation Genetics in 2011 suggests the returning dogs came from the same population, so they had survived somewhere nearby. The dates rest on secondary summaries of that research.
Today's numbers are thin. The census table gives 20 adults in 2 packs for the Mara as a 2021 estimate and no 2025 figure, and its own caption calls these guess estimates. Nationally the figure fell from 645 adults in 59 packs in 2021 to 310 in 38 packs in 2025. Seven per cent of Expert Africa travellers saw a wild dog, and no camp should promise you one.
The migration: 1.3 million, or fewer than 600,000?
The migration is usually put at about 1.3 million wildebeest, plus zebra and gazelle. A satellite survey published in PNAS Nexus in 2025 counted fewer than 600,000 wildebeest in August 2022 and 2023 over more than 4,000 km2, and calls the 1.3 million figure largely unchanged since the 1970s. The authors accept that different survey coverage explains part of the gap, so the true figure is now disputed.
The herds spend most of the year in Tanzania and reach the Kenyan Mara roughly from July to October. In 2025 they began arriving at Sand River on 6 July and first crossed into the Triangle on 25 July. In 2026 a rainstorm on 17 August sent about 200,000 animals in the Triangle back into the Serengeti. The Mara Conservancy reports only about 14 days of crossings in the main reserve in 2025, down from 29 the year before and 50 in the past, and says only half as many wildebeest now visit the Mara.
The 26,878 wildebeest in the June 2024 count are a separate population: the resident Loita and Mara herd, there all year.
Birds in the Masai Mara: more than 470 species
The Mara Conservancy's bird list says more than 470 species have been recorded inside the reserve, and Nature Kenya's profile of the Mara as an Important Bird Area puts the wider ecosystem above 500, including 12 cisticolas and 53 birds of prey. The Triangle list includes Pel's fishing owl, Usambiro barbet and rufous-bellied heron alongside the grey crowned crane.
Migrants from Europe and Asia, white stork, Caspian plover, corn crake, European roller and a range of raptors among them, are present in the northern winter months. No primary source we found gives arrival dates for the Mara itself, so plan on the northern winter rather than a particular week.

What is rare, and what nobody has checked
None of the eight species this network rates is absent from the Mara. The genuine rarities are wild dog, striped hyaena, which 11 to 13 per cent of travellers see, and the nocturnal pangolin and aardvark at 0 to 3 per cent. The 2024 census found only 6 gerenuk and 5 lesser kudu across the whole ecosystem, so both are edge-of-range animals here.
Roan, sable, oryx, Grevy's zebra and reticulated giraffe are northern or western species and are not expected in the Mara. No source we read states their absence, so this page does not rate them.
Not published on this page for lack of a primary source: elephant densities by zone (the 2021 Mara survey report is offline), a numeric confidence interval for the lion estimate, a reserve-wide leopard figure, the 2023 Tanzanian aerial estimate of the migration, and arrival months for the Palearctic migrants.
