81-606: The Fort Worth Zoo is accredited by both the Association of Zoos and Aquariums (AZA) and Zoological Association of America (ZAA), and is a member of the World Association of Zoos and Aquariums (WAZA). When the Fort Worth Zoo opened in 1909, it had one African lion , two bear cubs, an alligator , a coyote , a peacock and a few rabbits . From its opening until 1991, the zoo was owned and operated by

162-518: A combination of several threats. It is a charismatic species and is popular with tourists. Other vernacular names of the species include black-footed penguin and jackass penguin , due to the species' loud, donkey-like noise (although several related species of South American penguins produce the same sound). They can be found along the coast of South Africa and Namibia . In 1747, the English naturalist George Edwards included an illustration and

243-693: A conference in September, one of the largest zoo and aquarium professionals' events in the US. AZA also manages the citizen science program FrogWatch USA . In the United States, any public animal exhibit must be licensed and inspected by the United States Department of Agriculture , United States Environmental Protection Agency , Drug Enforcement Administration , Occupational Safety and Health Administration , and others. Depending on

324-580: A description of the African penguin in the second volume of his A Natural History of Uncommon Birds . He used the English name "The Black-Footed Penguins". Edwards based his hand-coloured etching on two preserved specimens that had been brought to London . He suspected that they had been collected near the Cape of Good Hope . When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for

405-456: A diet of anchovies appears to be generally sufficient for the penguins, it is not ideal due to anchovies' lower concentrations of fat and protein. The Penguin's diet changes throughout the year; as in many seabirds, it is believed that the interaction of diet choice and breeding success helps the penguins maintain their population size. Although parent penguins are protective of their chicks, they will not incur nutritional deficits themselves if food

486-575: A few days before a collecting effort to ensure that only freshly laid eggs were sold. This added to the drastic decline of the African penguin population around the Cape coast, a decline which was hastened by the removal of guano from islands for use as fertiliser, eliminating the burrowing material used by penguins. Penguins remain susceptible to pollution of their habitat by petrochemicals from spills, shipwrecks and cleaning of tankers while at sea. Accounts of African penguins impacted by oil date back to

567-446: A male-biased adult sex ratio and may indicate that conservation strategies focused on benefiting female African penguins may be necessary. The average lifespan of an African penguin is 10 to around 25 years in the wild and up to 30 in captivity. The primary predators of African penguins at sea include sharks and fur seals . While nesting: kelp gulls , Cape genets , mongooses , caracals and domestic cats and dogs may prey on

648-473: A renovated African Savanna, opened in April 2018. The second step in this plan, an expanded elephant exhibit, opened in April 2021. The other upcoming projects are renovated exhibits for the various African and Asian carnivores, and a new Forests & Jungles section. Species here include the clouded leopard , African wild dog , Malayan tiger , African Lion , cheetah , striped hyena , and African leopard for

729-565: A renovated Australian Outback exhibit, and the penguin exhibit in 2008. This decade also saw the closing of the original Herpetarium in 2009 to be replaced by the Museum of Living Art in 2010. In the autumn of 2016, the zoo announced its $ 100-million capital campaign: A Wilder Vision, which will include new exhibit space, renovated habitats, special events space, multiple dining areas, restrooms and most importantly, new ways to observe, interact with and learn about animals. The first step in this plan,

810-404: A token collection and, under the direction of a professional staff, provides its collection with appropriate care and exhibits them in an aesthetic manner to the public on a regularly scheduled basis. They shall further be defined as having as their primary business the exhibition, conservation and preservation of the earth's fauna in an educational and scientific manner." To achieve accreditation,

891-494: A very recognisable appearance, with a thick band of black that is in the shape of an upside-down horseshoe. They have black feet and black spots that vary in size and shape between individuals. Magellanic penguins share a similar bar marking that often confuses the two; the Magellanic has a double bar on the throat and chest, whereas the African has a single bar. These penguins have the nickname "jackass penguin", which comes from

The exhibit includes 500 animals representing 86 species, including clownfish , angelfish , brain corals , stingrays and sea apples . Opened in 2018, the African Savanna allows guests to see reticulated giraffes , lesser kudu , springbok , ostriches , southern ground hornbills , Cape vulture , pink-backed pelicans , and helmeted guineafowl from multiple viewing spots, including an elevated boardwalk that allows giraffe feeding. There are also several paddocks for southern black rhinos , an above and underwater viewing area of

1134-710: Is awarded. This accreditation process is repeated once every five years. AZA estimates that there are approximately 2,800 animal exhibits operating under USDA license as of 2019; fewer than 10% are accredited. Certification is possible for facilities that hold animals, but are not regularly open to the public. AZA's Saving Animals From Extinction (SAFE) program prioritizes collaboration between zoos and aquariums to support highly vulnerable species. SAFE builds on existing recovery plans to implement strategic conservation and public engagement activities. In 2017, AZA member zoos and aquariums invested $ 15.6 million towards SAFE program species. The SAFE program signature species include

1215-593: Is from Ancient Greek word σφήν ( sphēn ) meaning "wedge" and is a reference to the animal's thin, wedge-shaped flippers. The specific epithet demersus is Latin meaning "plunging" (from demergere meaning "to sink"). Banded penguins are found mainly in the Southern Hemisphere with the Humboldt penguin and Magellanic penguins found in southern South America and the Galápagos penguin found in

1296-570: Is home to two of the four species of flamingos at the zoo. The exhibit includes two species of flamingo, the American flamingos and Chilean flamingos with both, as well the zoo's greater and lesser flamingos, being successfully bred. This exhibit has been renovated and now includes the Great Barrier Reef exhibit in addition to being home to the zoo's galah , red kangaroos & Australian brushturkey The Great Barrier Reef exhibit

1377-793: Is largely restricted to 24 islands from Namibia to Algoa Bay, South Africa, with the Boulders Beach colony being an exception to this rule. The total population fell to approximately 150,000–180,000 in 2000. Of those, 56,000 belonged to the Dassen Island colony and 14,000 to the Robben Island colony. The colony at Dyer Island in South Africa fell from 46,000 in the early 1970s to 3,000 in 2008. In 2008, 5,000 breeding pairs were estimated to live in Namibia. In 2010,

1458-790: Is one of the species to which the African-Eurasian Waterbird Agreement (AEWA) applies. In September 2010, it was listed as endangered under the US Endangered Species Act . As of 2024, the African penguin is listed as critically endangered on the IUCN Red List , with the remaining mature individuals around 19,800 birds in a declining population. Many organisations such as SANCCOB , Dyer Island Conservation Trust, SAMREC , The National Aviary in Pittsburgh, and Raggy Charters with

1539-450: Is scarce and hunting requires a greater time or energy commitment. This may lead to higher rates of brood loss under poor food conditions. When foraging, African penguins carry out dives that reach an average depth of 25 m (82 ft) and last for 69 seconds, although a maximum depth of 130 m (430 ft) and duration of 275 seconds has been recorded. The African penguin is monogamous ; it breeds in colonies and pairs return to

1782-471: The Treasure oil spill, the species is considered a good "candidate for a captive-breeding programme which aims to release offspring into the wild"; however, worry about the spread of new strains of avian malaria is a major concern in the situation. Bringing the birds inland led to the exposure of penguins to parasites and disease vectors such as mosquitoes carrying avian malaria, which has caused 27% of

1863-673: The University of Cape Town 's FitzPatrick Institute of African Ornithology found that rehabilitating oiled African penguins has resulted in the current population being 19% larger than it would have been in the absence of SANCCOB's rehabilitation efforts. In February 2015, the Dyer Island Conservation Trust opened the African Penguin and Seabird Sanctuary (APSS) in Gansbaai , South Africa. The centre

Texas Wild! was opened in 2001 to display various animals native to Texas. This section includes a carousel with hand-painted ponies. Texas Town includes a play barn and the Texas Hall of Wonders, and prepares visitors for the rest of the exhibit. High Plains and Prairies represents

2106-686: The pumping of bilges at sea had killed tens of thousands of African penguins. At the time, the Dassen Island colony was being passed by 650 oil tankers each month because the Suez Canal had become blocked with wrecked vessels, thus increasing maritime traffic past the Cape of Good Hope. In 1979, an oil spill prompted the collection and treatment of 150 African penguins from St. Croix Island near Port Elizabeth. The animals were later released at Robben Island and four of them promptly swam back to St. Croix Island, surprising scientists. In 1983,

2187-535: The tenth edition , he placed the African penguin with the wandering albatross in the genus Diomedea . Linnaeus included a brief description, coined the binomial name Diomedea demersa and cited Edwards' work. The African penguin is now placed with the banded penguins in the genus Spheniscus that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson . The genus name Spheniscus

2268-406: The 1930s. African penguins' exposure to oil spills is both chronic (higher frequency small discharges of oil at sea) and acute (rare maritime disasters where large volumes of oil are released in a single event). Penguins of many species have been impacted by oil spills across the southern hemisphere. In 1948, the tanker Esso Wheeling sank, subsequently oiling and killing thousands of penguins of

2592-573: The American Institute of Park Executives. In 1966, the American Association of Zoological Parks and Aquariums became a professional branch affiliate of the newly formed National Recreation and Park Association , which absorbed the American Institute of Park Executives. In the fall of 1971, the American Association of Zoological Parks and Aquariums membership voted to become an independent association. On January 19, 1972, it

2673-783: The City of Fort Worth. Although the city collected money from the community to purchase new animals, the Zoological society (now the Fort Worth Zoological Association) was formed in 1939 to help raise additional funds. Monkey Island was built in 1937 with funds from the Works Progress Administration . After being refurbished in 1949, this exhibit became a sea lion pool, and by 1970, it had been converted to house small South American mammals. Storks and cranes were housed in this exhibit in

This was the largest animal rescue event in history; more than 91% of the penguins were successfully rehabilitated and released – an amazing feat that could not have been accomplished without such a tremendous international response. Due to the positive outcome of African penguins being raised in captivity after tragedies such as

2835-645: The Dyer Island colony. In 1953, dead penguins were among a range of dead birds, fish and other marine life that washed ashore after the tanker Sliedrecht was holed and spilled oil near Table Bay . In 1971, the SS Wafra oil spill impacted the African penguin colony of Dyer Island. In 1972, oil spilt following the Oswego-Guardian and Texanita collision oiled roughly 500 penguins. In 1975, newspapers reported that oil pollution from shipwrecks and

2916-507: The Endangered Species Act. In 2017, member institutions reported participating in field conservation projects benefiting over 860 species in 128 countries. AZA zoos and aquariums spent $ 25 million on research and published 170 books, book chapters, journal articles, conference proceeding papers, posters and theses or dissertations.

Brush Country represents Southern Texas. This section includes bobcats , cougars , coyotes , jaguars , ocelots , ring-tailed cats , and white-nosed coati , as well as several native species of birds of prey such as

3726-522: The band. The beak is more pointed than that of the Humboldt penguin . The African penguin's colouring is a form of protective colouration known as countershading . The white undersides of the birds are difficult to spot by predators under the water and the penguins' black backs blend in with the water when viewed from above. African penguins resemble and are thought to be related to the Humboldt, Magellanic and Galápagos penguins. African penguins have

3807-426: The biodiversity of Texas. Money from this fund has gone towards multiple projects such as training search dogs to locate Houston toads , genetic assessments for ornate box turtle populations, and development for conservation strategies for alligator snapping turtles . The zoo and their conservation biologists also host and are a part of many conservation projects, such as projects seeking to increase populations for

3888-455: The chicks join a crèche with other chicks and both parents spend most of the day foraging in the sea. Chicks fledge at 60 to 130 days, the timing depending on environmental factors such as the quality and availability of food. The fledged chicks then go to sea on their own, where they spend the next one to nearly two years. They then return to their natal colony to moult into adult plumage. When penguins moult , they are unable to forage in

3969-580: The culling of individual problem animals, which has been found effective (although requiring a large amount of management effort) in trials. Established in 1968, SANCCOB is currently the only organisation mandated by the South African government to respond to crises involving seabirds along South Africa's coastline and is internationally recognised for the role it played during the MV Treasure oil spill. A modelling exercise conducted in 2003 by

4050-507: The day while the parents forage. The chicks are frequently killed by predators or succumb to the hot sun. Parents usually feed hatchlings during dusk or dawn. In 2015, when foraging conditions were favourable, more male than female African penguin chicks were produced in the colony on Bird Island. Male chicks also had higher growth rates and fledging mass and therefore may have higher post-fledging survival than females. This, coupled with higher adult female mortality in this species, may result in

4131-456: The eggs are incubated in a burrow dug into the guano layer (which provides suitable temperature regulation), but the widespread human removal of guano deposits has rendered this type of nest unfeasible in many colonies. To compensate, penguins burrow holes in the sand, nest under rocks or bushes or make use of nest boxes if they are provided. The penguins spend three weeks on land caring for their offspring, after which chicks may be left alone during

4212-676: The elephants, visitors can go past the entrance and either go to the River Village or check out a viewing area that gives a better view of the Indian rhinoceros with a path leading to the Predators of Asia and Africa section. The exhibit also features a Demonstration Area for an elephant encounter show. This new exhibit was opened on June 22, 2023. It includes huge yards for returning carnivores like lions , cheetahs , African wild dogs , and new addition of African leopards . The half that

4293-609: The exposure of penguins of Dassen Island to the oil slick from the Castillo de Bellver was also a topic of concern given the penguins' conservation status at the time, but owing to the prevailing wind and current, only gannets were oiled. African penguin casualties were significant following the sinking of the MV Apollo Sea and a subsequent oil slick in 1994. 10,000 penguins were collected and cleaned, of which less than half survived. Disaster struck on 23 June 2000, when

4374-412: The eyes and a black facial mask. The body's upper parts are black and sharply delineated from the white underparts, which are spotted and marked with a black band. The African penguin is a pursuit diver and feeds primarily on fish and squid. Once extremely numerous, the African penguin is now the rarest species of penguin classified as critically endangered , with its population declining rapidly due to

4455-416: The eyes cool the birds' blood and as the temperature rises, increased blood flow causes the glands to get pinker. This species exhibits slight sexual dimorphism ; the males are slightly larger than the females and have longer beaks. Juveniles do not possess the bold, delineated markings of the adult, but instead have dark upperparts that vary from greyish-blue to brown; the pale underparts lack both spots and

4536-627: The facility also included a zoo hospital and quarantine room. Features such as refrigerated air, operational skylights, temperature controlled water, switch operated emergency alarms, and state-of-the-art service facilities, made the Herpetarium a marvel of technology for its time. Innovative exhibits such as a display of giant snakes with curved non-reflective glass (creating the illusion of an open-fronted exhibit) were especially popular attractions. The main public area included five exhibit halls covering various geographic regions and another area that

4617-710: The iron ore tanker MV Treasure sank between Robben Island and Dassen Island , South Africa. It released 400–1,000 tonnes (390–980 long tons; 440–1,100 short tons) of fuel oil, causing an unprecedented coastal bird crisis and oiling 19,000 adult penguins at the height of the best breeding season on record for this vulnerable species. The oiled birds were brought to an abandoned train repair warehouse in Cape Town to be cared for. An additional 19,500 un-oiled penguins were removed from Dassen Island and other areas before they became oiled and were released about 800 kilometres east of Cape Town. This gave workers enough time to clean up

4698-421: The late 1950s, some French chefs expressed interest in recipes including African penguin eggs collected from the islands off the west coast of South Africa and placed annual orders for small quantities. In the mid-1960s, eggs were collected in the thousands and sold by the dozen, with each customer limited to two dozen eggs in total. The practice of collecting African penguin eggs involved smashing those found

4779-721: The loud penguin noises they make. The African penguin is only found on the southwestern coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay , near Port Elizabeth , South Africa. It is the only penguin species that breeds in Africa and its presence gave name to the Penguin Islands . Two colonies were established by penguins in the 1980s on the mainland near Cape Town, namely Boulders Beach near Simon's Town and Stony Point in Betty's Bay . Mainland colonies likely became possible only in recent times due to

4860-413: The mainland, African penguins will seek protection on offshore islands, where they are safer from larger mammals and natural challenges. These penguins usually breed during the winter when temperatures are cooler. African penguins often will abandon their eggs if they become overheated in the hot sun and abandoned eggs never survive the heat. The eggs are three to four times bigger than chicken eggs. Ideally,

4941-570: The oiled waters and shores before the birds could complete their long swim home (which took the penguins between one and three weeks). Some of the penguins were named and radio-tracked as they swam back to their breeding grounds. Tens of thousands of volunteers helped with the rescue and rehabilitation process, which was overseen by the International Fund for Animal Welfare (IFAW) and the South African Foundation for

Penguins normally swim within 20 km (12 mi) of

5103-428: The penguins and their chicks. Mortality from terrestrial predators is higher if penguins are forced to breed in the open in the absence of suitable burrows or nest boxes. African penguin eggs were considered a delicacy and were still being eaten and collected for sale as recently as the 1970s. In the 1950s, they were being collected from Dassen Island and sold in nearby towns. In 1953, 12,000 eggs were collected. In

They participate in 115 reintroduction programs, including more than 40 programs for species listed as threatened or endangered under

5265-576: The public on a predictable basis. African penguins Diomedea demersa Linnaeus, 1758 The African penguin ( Spheniscus demersus ), also known as Cape penguin or South African penguin , is a species of penguin confined to southern African waters. Like all penguins, it is flightless , with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults weigh an average of 2.2–3.5 kg (4.9–7.7 lb) and are 60–70 cm (24–28 in) tall. The species has distinctive pink patches of skin above

5346-517: The reduction of predator numbers, although the Betty's Bay colony has been attacked by leopards . The only other mainland colony is in Namibia, but it is not known when it was established. Boulders Beach is a tourist attraction due to the beach, swimming and the penguins. The penguins will allow people to approach them as close as a meter. Breeding populations of African penguins are being kept in numerous zoos worldwide. No colonies are known outside

5427-629: The rehabilitated penguin deaths annually. Small-scale oil spills (of less than 400 litres (110 US gal)) have occurred at the Port of Ngqura since bunkering activities started there in 2016. Bunkering is a ship refuelling process that can result in oil spills and oil slicks entering the water. Hundreds of African penguins have been harmed following these spills due to the port's close proximity to penguin rookeries on St. Croix Island and seabird habitat on neighbouring Jahleel and Brenton Islands. Commercial fisheries of sardines and anchovy ,

A clutch of two eggs is laid either in burrows burrowed in guano or nests in the sand under boulders or bushes. Incubation is undertaken equally by both parents for around 40 days. At least one parent guards the chicks for about one month, whereafter

5589-427: The sea as their new feathers are not yet waterproof; therefore, they fast over the entire moulting period. African penguins typically take around three weeks to moult and lose about half of their body weight by burning up their fat reserves in the process. African penguins spend most of their lives at sea until it comes time for them to lay their eggs. Females remain fertile for about 10 years. Due to high predation on

5670-437: The shore. A penguin may consume up to 540 grams (1.19 lb) of prey every day, but this may increase to over 1 kg (2.2 lb) when raising older chicks. Due to the marked decline of sardines in the waters near its habitat, African penguins' diet has shifted towards anchovies to some extent, although available sardine biomass is still a notable determinant of penguin population development and breeding success. While

5751-462: The southwestern coast of Africa, although vagrants (mostly juveniles) may occasionally be sighted beyond the normal range.
