As of June 2011, the male "Survivor" and two females are living in Basel with two young cheetahs. On June 17, 2009, mother Msichana had two males and a female baby. The youngest cheetah died in the fall of 2009.

As of June 27, 2010, Basel's flamingo herd counts 113 individuals. During the spring of 2010, these birds built 41 nests and between June 5 and June 29, 2010 thirty-three flamingos hatched - of which thirty survived. This is a new record for the zoo, that never had these many flamingo hatches in its history. In a media release on June 22, 2010 zoo officials consider a calm hatching time and ideal weather as reasons for this record.[11]

Zoo Basel hatched the first flamingo, a Chilean flamingo in a European zoo in 1958 and a year later the first greater flamingo in captivity.[12] While at first Zoo Basel had all six flamingo species, it decided to focus on the greater flamingo in the 1980s.

As of September 2012, Ellora (1982), Quetta (1993), Jaffna (Basels stock bull / 1994), Henna (2010), and Jari (2012) live in the Zolli.[14][15] On July 23, 2010, Ellora gave birth to a rhino girl called Henna, which is Ellora's seventh baby. Henna is unique in Basel's breeding history, as her left front leg is white. A video of Henna's birth can be watched here: rhino birth[3]

In 1952, the first rhino, the bull Gadadhar, arrived in Basel and a year later, the female Joymothi followed. These two animals are the parents of Basel's Indian rhino breeding program.

On September 14, 1956, the birth of rhino boy Rudra (the first Indian rhino born in a zoo) started Basel's Indian rhino success story.[16] He was the son of Gadadhar and Joymothi that came from Kaziranga National Park. Two hours after birth he weighed 60.5 kg (133 lb) and was 105 cm (41 in) long and quickly gained 1.5 kilograms per day. In 1959, Rudra was transferred to the Milwaukee County Zoo, where he only became a father once until his death.[17]

As of September 2012, 33 Indian rhinos have been born in Basel[15] out of about 80 births worldwide. Therefore, most of the 174 Indian rhinoceroses in zoos around the globe are somehow related to the rhino population in Basel.[3]

Rhino with otter

The Indian rhinoceros house and outdoor exhibit were built in 1959, extensively renovated from 2006 to 2008, and re-opened in May 2008. In the new rhinoceros exhibit, the rhinos, are sharing the outdoor exhibit with muntjacs, and Oriental small-clawed otters. As of July 2010, the three different species lived together with no incidents. The 2.5-ton-rhinoceroses are sharing their food with the 30-kilogram-muntjacs or go into one of four ponds where the Asian otters are swimming around the rhinos.

The Zolli supports Indian Rhino Vision 2020, which intends to increase the wild Indian rhino population to 3'000 animals. The partnership with the Orang National Park in India, where currently about 60 rhinos live, is one of the projects supported. In 2008, out of every day pass sold 15 Rappen (US$0.14) and out of every annual pass CHF 1.50 ($1.45) went to the Rhino Vision, totaling CHF 100'000 ($99,900).[18]

On December 2, 2009, the okapi bull Stomp (b. 2003) came from Zoo Berlin and on August 24, 2011 the female Hazima (b. 2007) arrived from the British Marwell Wildlife.[19]

The first okapi that arrived in Basel on June 16, 1949, was the bull Bambe. However, after only 66 days, he died due to liver parasites. Nanouk (1955) and Bibi (1956) followed him and laid the foundation of Basel's successful okapi breeding program.[20]

In 2008, Basels Ahadi fathered the first okapi birth in the Czech Republic and Slovakia at Zoo Dvur Kralove. A video of this birth can be seen here[21] on YouTube.

All okapi zoos (including Basel) in Europe and North America are supporting the Okapi Wildlife Reserve managed by the Gilman International Conservation Organization, in the Ituri Rainforest (Democratic Republic of the Congo). In 2008, Zoo Basel donated $5,000 to the Gilman Conservation.[22]

In 1928, the first animals arrived in Basel and started a breeding program in which 53 hippos were born and successfully raised.[23] These animals and their offspring are living today in zoos all over the globe.

As of December 16, 2010, there are four Somali wild donkeys in Basel: The stallion "Ares" (22), three females (among them "Yogala"-12), and the baby girl "Hakaba."[6]

Basel started having Somali wild asses in 1970 and had its first birth in 1972. Since then, 11 stallions and 24 females were born and survived childhood.[28]

Zoo Basel supports a conservation project in the Northeast African country of Eritrea, where 47 Somali wild ass live in the mountains between the Buri Peninsula and the Dalool ditch.[29]
