Flamingoes and Grebes

At the top of the page is an image of every species of flamingo, below you will find some information on each species. Below this, you will find the same for the grebes.

As always, should you work in tourism or conservation of any of these species, do get in touch, we are keen to help people find you. Click on list your wild place on the homepage main menu.

American Flamingo

Found in the West Indies, northern South America (including the Galápagos Islands) and the Yucatan Peninsula. It was considered cospecifc with the greater flamingo, but they are now recognized as separate species (it is also closely related to the Chilean flamingo). 

Formerly it was a culture icon in Southern Florida, but was largely extirpated by 1900. Having said this, there are vagrant flamingos in Florida, and these now often stay in the country worldwide.

There are 80,000-90,000 left in the wild, and there are 4 breeding colonies: in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago, Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical and subtropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and formerly southern Florida in the United States).

Andean Flamingo

Found in the Andes mountains of South America, it is in the same genus as the James Flamingo. Indeed, the Chilean Andea and James flamingo often share nesting sites and are relatively closely related.

It is considered vulnerable to extinction with roughly 34,000 remaining in the wild, but declining over time.

As with other flamingos they are filter feeders, though what they filter can vary from algae to small fish – which they look for in shallow salty water.

They migrate between salt lakes in the summer and lower wetlands in winter – with the capacity of covering 700 miles a day.

The threat that this species faces, is generally due to human activity of mining and other changes to their habitat.

Chilean Flamingo

Closely related to the American and greater flamingo, it is listed as near threatened in the wild with a wild population of about 200,000. Population declines are due to habitat loss and degradation, harvesting and human disturbance.

While they are only currently listed as near threatened, there is a great deal of concern about falling populations, and as such they are relatively common in zoos and there is an active breeding program..

 

Greater Flamingo

The greaterflamingo has the greatest of ranges of any species (as you can see from the map. While it is found down the East coast of Africa, it is also found on the northwest coast and the northern coast. It is also present in the middle east, and throughout much of Sothern Europe. Its range also extends into India. It is listed as least concern with a population between 550,000 and 680,000 with between 45,000 and 125,000 living in Europe – the Camargue is the most famous in Southern France

They are listed as least concern

 

James Flamingo

The James flamingo is also found on the high Andean plateau, and is closely related to the Andean Flamingo. It was thought extinct until a population was rediscovered in 1956, and the current population is thought to be around 106,000.

It is currently listed as near threatened, and on CITES appendix 2.

Lesser Flamingo

Found in Sub-Saharan Africa and India. While the smallest species, it still stands 80-90cm tall. The easiest way to tell this and the greater flamingo (with overlapping range) apart is that the greater flamingo has more black on its bill.

Estimates on the number of this species range from “above” 2 million to as much as 5 million.

They generally breed in highly caustic lakes of the great rift valley in Africa, though there are places in India and a few other places as well.

They are classed as near threatened. While their choice of nesting site protects from many predators, it is still true that many flamingos are killed. From fish eagles to baboons and big cats, there are many species who will eat a flamingo if they can get hold of it.

It is well worth seeing this animal in the wild. Seeing 750,000 lesser flamingos on lake nakuru in kenya is a site that is hard to forget.

Visits to see flamingos are well worth it, and while some live in remote places, it is usually a species which is reliable. Please get in touch if you work in tourism or conservation of this species. Click on list your wild place on the home page of the website.

Aragualan River Dolphin

Araguaian river dolphin by Rio Cicica

Araguaian river dolphin

The Araguaian river dolphin or Araguaian boto  is a South American river dolphin population native to the Araguaia–Tocantins basin of Brazil.

The recognition of I. araguaiaensis as a distinct species is still debated. It was originally distinguished from the Amazon river dolphin in January 2014. On the basis of nuclear microsatellite and mitochondrial DNA data as well as differences in skull morphology (it generally has a wider skull). It also differs from the Amazon and Bolivian river dolphins in the number of teeth per hemimandible (24–28 versus 25–29 and 31–35, respectively).

River dolphins have a complex set of acoustic calls that help shed light on their personalities, behaviours and interaction with other river dolphins. In a study by Gabriel Melo-Santos et. Al they analysed frequency contours of 727 signals They found that these signals had a critical similarity value of 96% and frequency contours were categorized into 237 sound-types. Interestingly the most notable and frequent sounds were emitted when calves were present shedding light on a close and complex mother child relationship. The findings show that the acoustic sounds of river dolphins are incredibly complex and are similar to those of by social delphinids, such as orcas and pilot whales.

The total population of the species is estimated to be of the order of 600 to 1500 individuals, and genetic diversity is limited.[4] The ecology of its habitat has been adversely affected by agricultural, ranching and industrial activities, as well as by the use of dams for hydroelectric power. The inhabited section of the Araguaia River probably extends over about 1500 km out of a total length of 2110 km. The Tocantins River habitat is fragmented by six hydroelectric dams, so the population there is at particular risk.[4] The authors of the discovery paper regard its probable eventual IUCN status to be Vulnerable or worse.

The largest number of individuals of the new species is likely to occur in and around Cantão State Park, which contains most of the lakes in the Araguaia basin. However, commercial fishermen around the park have been killing them because they sometimes steal fish from nets. Shooting is common, but around protected areas like Cantão, where the sound of a gun might attract park rangers, some fishermen have taken to putting out poisoned bait for dolphins. The southernmost population of the species is a small group of isolated individuals in the Tocantins river above the Serra da Mesa dam.

Below you will find a list of any articles which mention this species specifically, below that is a video of this species in the wild. Below this, we will list any tourism opportunities (if any that we connect with).

Spinner Dolphin

Spinner dolphin

The spinner dolphin (also known as the long-snouted dolphin (distinguishing it from the Clymene dolphin – which is often called the short snouthed spinner dolphin) is a small dolphin found in off-shore tropical waters around the world. It is famous for its spinning  along its length, as it leaps from the water. It is a member of the family Delphinidae of toothed whales.

The four named subspecies are:

  • Eastern spinner dolphin, found from the tropical eastern Pacific.
  • Central American or Costa Rican spinner dolphin, also found in the tropical eastern Pacific.
  • Gray’s or Hawaiian spinner dolphin, from the central Pacific Ocean around Hawaii but represents a mixture of broadly similar subtypes found worldwide.
  • Dwarf spinner dolphin, first found in the Gulf of Thailand.

The species, though, displays greater variety than these subspecies might indicate. A hybrid form characterized by its white belly inhabits the eastern Pacific. Other less distinct groupings inhabit other oceans.The species name comes from the Latin word for “long-beaked.”

Spinner dolphins are small cetaceans with a slim build. Adults are 129–235 cm long and weigh 23–79 kg. This species has an elongated rostrum and a triangular or subtriangular dorsal fin. Spinner dolphins generally have three colours, one on the dorsal fin, one on the underside and one on the upper-side. Also, a dark band runs from the eye to the flipper, bordered above by a thin, light line. However, the spinner dolphin has more geographic variation in form and coloration than other cetaceans. In the open waters of eastern Pacific, dolphins have relatively small skulls with short rostra. A dwarf form of spinner dolphin occurs around southeast Asia. In these same subspecies, a dark dorsal cape dims their tripartite colour patterns Further offshore, subspecies tend to have a paler and less far-reaching cape.] In certain subspecies, some males may have upright fins that slant forward.[8] Some populations of spinner dolphin found in the eastern Pacific have backwards-facing dorsal fins, and males can have dorsal humps and upturned caudal flukes.

The spinner dolphin lives in nearly all tropical and subtropical waters between 40°N and 40°S. The species primarily inhabits coastal waters, islands, or banks. However, in the eastern tropical Pacific, spinner dolphins live far from shore. Some studies suggest they use different areas at different times of the year.

The spinner dolphin feeds mainly on small mesopelagic fish, squids, and sergestid shrimps, and will dive 200–300 m to feed on them. Spinner dolphins of Hawaii are nocturnal feeders and forage in deep scattering layers, which contain many species. The dwarf spinner dolphin may feed mostly on benthic fish in reefs and shallow water. Off Oahu, Hawaii, spinner dolphins forage at night and cooperatively herd their prey into highly dense patches. They swim around the prey in a circle and a pair may swim through the circle to make a catch. Spinner dolphins are in turn preyed on by sharks. Other possible predators include the killer whale, the false killer whale, the pygmy killer whale and the short-finned pilot whale. They are susceptible to parasites, and are known to exhibit both external ones like barnacles and remoras as well as internal parasites.


Due to the spinner dolphin foraging and feeding at night, in certain regions, such as Hawaii and northern Brazil, dolphins spend the daytime resting in shallow bays near deep water. Spinner dolphins rest as a single unit, moving back and forth slowly in a tight formation but just out of contact with one another. These resting behaviours are observed for about four to five hours daily. During rest periods, spinner dolphins rely on vision rather than echolocation. At dusk, they travel offshore to feed. They travel along the shore during foraging trips, and the individuals that occupy the same bay may change daily. Some individual dolphins do not always go to a bay to rest; however, in Hawaii, dolphins do seem to return to the same site each trip.

Spinner dolphins live in an open and loose social organization. The spinner dolphins of Hawaii live in family groups, but also have associations with others beyond their groups. Mothers and calves form strong social bonds. Spinner dolphins seem to have a promiscuous mating system, with individuals changing partners for up to some weeks. A dozen adult males may gather into coalitions. Vocalizations of spinner dolphins include whistles, which may be used to organize the school, burst-pulse signals, and echolocation clicks. The spinner dolphin has a 10-month gestation period, and mothers nurse their young for one to two years. Females are sexually mature at four to seven years, with three-year calving intervals, while males are sexually mature at seven to 10 years. Spinner dolphins live for about 20-25 years old. Breeding is seasonal, more so in certain regions than others.

Although most spinner dolphins are found in the deeper waters offshore of the islands, the rest of the Hawaiʻi population has a more coastal distribution. During daytime hours, the island-associated stocks of Hawaiian spinner dolphins seek sanctuary in nearshore waters, where they return to certain areas to socialize, rest, and nurture their young.

They get their name for their spinning jumps, a spinner dolphin comes out of the water front first and twists its body as it rises into the air. When it reaches its maximum height, the dolphin descends back into the water, landing on its side. A dolphin can make two to seven spins in one leap; the swimming and rotational speed of the dolphin as it spins underwater affects the number of spins it can do while airborne. These spins may serve several functions. Some of these functions are believed by experts to be acoustic signalling or communication. Another reason is to remove ectoparasites such as remoras. Dolphins may also make nose-outs, tail slaps, flips, head slaps, “salmon leaps”, and side and back slaps.

The protected status of spinner dolphins are CITES Appendix II and Marine Mammal Protection Act (MMPA) protected throughout its range as well as MMPA depleted in its eastern stock. Tens of thousands of spinner dolphins, mostly eastern and white-bellied varieties, were killed in the 30 years after purse seine fishing for tuna began in the 1950s; The process killed probably half of all eastern spinner dolphins. They have also been contaminated by pollutants such as DDT and PCBs. Spinner dolphins, as with other species affected by ETP tuna purse-seine fishing, are managed nationally by the coastal countries and internationally by the IATTC. The IATTC has imposed annual stock mortality limits on each purse seine and promulgated regulations regarding the safe release of dolphins. The eastern tropical Pacific and Southeast Asian populations of the spinner dolphin are listed on Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), since they have an unfavourable conservation status or would benefit significantly from international co-operation organized by tailored agreements. In addition, the spinner dolphin is covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MoU) and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia (Western African Aquatic Mammals MoU). Spinner dolphins are susceptible to disease and two of the recorded diseases within them are toxoplasmosis and cetacean morbillivirus. The number of cases reported however is fairly low in the species.

Spinner dolphins in Hawaii receive multiple daily visits to their near-shore resting grounds, with boats taking people out daily to snorkel and interact with the local dolphin population. Such activities are increasingly coming under criticism on the grounds of possible harm to the dolphins, and efforts are being made both to educate the public in order to minimise human impact on the dolphins, and to bring in regulations to govern these activities. In 2023, 33 swimmers were arrested for reportedly harassing dolphins off the coast of the Big Island of Hawaii. The swimmers reportedly broke federal law by swimming within 45 meters (50 yards) of the dolphins. The ban went into effect in 2021 due to dolphins not getting enough rest during the day to forage for food at night. The swimmers were caught by drone footage pursuing the dolphins as they tried to escape.

We are eager to work with people who run boats to see these animals – provided they are run with due care for the animals. Do get in touch, or fill in a form you will find in ‘List your wild place’ at the top of the page (or click here).

Burmeister Porpoise

Bermeister Porpoise

First described by Hermann Burmister in 1865, they are thought to have a population that numbers at least in the 10,000s. Found from Peru in the Pacific to Brazil in the Atlantic, while usually found in shallow coastal waters, they have been located 1000m down.

Most photos of this species are of a dead individual. It is black which explains its other name – the black porpoise, though it is thought that they turn black after death and are dark grey beforehand. The underside is lighter, though this is common as it helps with camouflage against the light surface of the water. Usually 1.5m in length and with a weight of 50-75kg, they can be mistaken for the Chilean dolphin, which is a similar size. Their dorsal fin is more triangular and points back rather than up so should not be confused.

They are shy, usually moving away from boats at a high speed. Usually seen in pairs or alone. However, they have been seen in larger groups, with a group spotted off the coast of Chile numbering 50.

Eating Hake, Maceral and Anchovies, which are all species impacted greatly by el nino. Many of the marine mammals in the area starved or struggled until the fish returned.

The Manned wolf

Looking, at first glance, like a fox on stilts, it is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay. It is actually not a wolf or a dog, but instead sits in its own genus Chrysocyon  which means “golden dog”. It is crepuscular and omnivorous, and lives on the open habitat of the South America Savanna. The IUCN classes it as near threatened, while a Brazilian organisation with a similar role lists it as vulnerable.

Its name in a local language calls it a big fox. Indeed some studies have suggested that it should be in the same genus as pseudo-foxes.

A recent study suggested that its nearest relative was the Falkland islands wolf, and its mainland relatives – but you have to go back 7 million years to find a common ancestor with this group.

It only hunts solitarily, and its preferred habitat is grasslands, scrub prairies, and forests.

It is not currently considered endangered, given its wide area in which it inhabits, never-the-less it is recognized as a near threatened species due to its reducing numbers. In Brazil, Argentina and Uruguay it is forbidden to hunt them. It has been used to publicize the fight to protect the Brazilian cerrado, by placing it on one of the Brazilian notes.

This animal was shown in great detail in planet earth 3 episode 3, however, this clip is from a bbc series a few years ago.

As we make contacts which you can use to plan your travel to see this animal for yourself.

The Pampas fox

The Pampas fox is also known as the grey pampean fox, Pampas zorro, Azara fox or Azara zorro. It is a midsized (non) fox as all south American foxes, which are more closely related to the wolf and jackal.

Pampas fox

The Pampas fox resembles the Culpeo or Andean fox in appearance and size, but has a proportionately wider snout, reddish fur on the head and neck, and a black mark on the muzzle. Its short, dense fur is grey over most of the body, with a black line running down the back and onto the tail, and pale, almost white, underparts.

The Pampas fox can be found in northern and central Argentina, Uruguay, eastern Bolivia, Paraguay, and southern Brazil. It prefers open pampas habitats, often close to agricultural land, but can also be found in montane or chaco forest, dry scrubland, and wetland habitats. It is most common below 1,000 m (3,300 ft) elevation, but can inhabit puna grasslands up to 3,500 m.

They are occasionally hunted for their fur, or to avoid livestock deaths, however thus far this has not impacted population.

Hoary Fox

Also known as Hoary zorro, its Brazilian name means little meadow fox. It primary feeds on insects,

Hoary fox

The Hoary fox is generally nocturnal and usually solitary except during the breeding season. They survive for the most part on insects such as termites, dung beetles and grasshoppers. They will also eat rodents, small birds and fruit. Their home range varies widely depending on how much food is available. An example is one adult in Southern Bahia whose home range covers 950 acres, however in the pastures of Minas Gerais a breeding pair with 5 young survived on 1130 acres, and in Eastern Mato Grosso 2 breeding pairs shared 120 acres.

They are mostly native to Southern central Brazil.

Margay

Margay

This is a relatively small wild cat that is found in central and Southern America, living in primary evergreen and deciduous forests. Until the 1990s they were illegally hunted for the wildlife trade, causing a significant decrease in the wild population. Sine 2008 they have been listed as near concern due to declining population, thought to be caused by habitat loss. It is classed as near threatened -one up from least concerned, but one down from Vulnerable.

Currently found from the Northern points of Mexico (it has not been seen in the USA since 1855 – indeed the only USA record comes from this time,, however fossils show it once ranged through Southern Texas, and may even have roamed as through Georgia Florida and South Carolina – or at least an animal very similar) through central America to Brazil and Paraguay and even reaching as far south as Uruguay and Argentina.It is a skilled climber, and is confident enough in the tree-tops to chase monkeys and birds for food. Its ankles are flexible enough to turn 180 to make it easier coming back down the tree. It is usually solitary, but lives in home ranges (meaning they are not territorial and home ranges will overlap) that cover 11-16 square km (4.2-6.2 square miles)

There are currently 3 recognized subspecies, these are in turn found South of the Amazon, North of the Amazon and in Central America.

 

The Oncilla (northern and Southern)

This is an Oncilla taken by Groumfy69 in a zoo

Oncilla (northern and southern)

The Oncilla is a small spotted cat found from central America to the Central Amazon. In 2013 it was proposed to split the species into two, as they did not interbreed, however I would argue that this should be at the subspecies level. The Southern Oncilla lives in Brazil, Paraguay and Argentina, while the Northern Oncilla ranges from central America to central Brazil – time will tell if these two cats are subspecies or are distinct enough to be considered different cat species

 

Jaguarundi

Rare in much of their range, with persecution and habitat loss, we yet have time to save this creature

The Jaguarundi is a mid-sized cat, similar in size to the Ocelot – about twice the size of a domestic cat. It is found from central Argentina to Northern Mexico at the top of its range. In central and Southern America it is found east of the Andes. Secretive, and very alert, it actually tends to hunt during the day and the evenings. They live in large home ranges and low densities. In the wild they tend to be solitary or living in pairs.

Although a good climber, it generally prefers to hunt on the ground. It lives in an array of habitats from tropical rainforests, deciduous forests to deserts and thorn scrubs.

It is pretty common in Brazil, Peru and Venezuela, though it is thought to be extinct in the USA – it is obviously found in the countries in between, however due to range loss from fragmentation of habitat, as well as direct persecution as a result of taking of poultry, there are many regions where it is threatened as populations are declining fast.

The Jaguarundi shares a clade with the mountain lion (cougar), and is in the same lineage as the Cheetah
