A question for everyone - What would you say are the most successful breeding programmes at your local zoo. I don't necessarily mean the actual volume of one animal that is being born. For example my local zoo is Colchester and I would say the Aardvarks and L'hoest monkey breeding programmes have been very successful.
For sheer volume, then the 2 groups of Visayan warty pigs at Chester seem to always have a litter each. I think the orangutans (at least the Sumatrans) seem to be pretty consistant in breeding as well.
For Chester I would also add Red Pandas, Giraffes, Meerkats and the Dwarf Mongoose seem to be getting there as well.
Fennec fox at Drusillas Park King Colobus at Blackpool Diana and De Brazza guenons at Port Lympne Lowland gorillas at Howletts Painted storks at Thrigby (though not in recent years). Pygmy hippopotamus at Marwell Iberian wolf at Howletts/PL Okapi at Marwell Tamandua (previously) and two-toed sloth at Amazon World Zoo.
Africa Alive have a outstanding record for breeding Fossa only bettered by a few big zoos in Germany.
marbled polecats - tropical wings elephants, black rhinos, gorillas, tigers - howletts/port lympne snow leopards - PWP
Leipzig Zoo (Germany): Lowland anoa (61 since 1972), Indian sloth bear (79 since 1963), dall sheep (68 since 1984), southern clouded rat, amur tiger (355 since 1914), Spotted hyaena, Owl-faced-monkey (28 since 1974), Sibirian musk deer (90 sind 1982), Sumatra orang utan (8 since 2000), African dwarf crocodile (56 since 1996)...
Well not my Local zoo (it couldnt get much less-local) but still my 'home' zoo: Newquay zoo - their pied tamarins do particularly well and were once (still are?) one of the best breeders in europe - phillipine deer they have only had these for a very short period but have proved quite successful - owstons civets breed regularly as do the sulawesi crested macaques (although this is less suprising and remarkable as they breed well pretty much anywhere)
Noahs Ark have bred a second Siamang Gibbon Bristols reptile house have bred Gila monster, golden mantellas and lemur leaf frogs.
Uhm let's see.... Off the top of my head, Belfast has had great success with the Barbary Lions....3 within one year was it? Also been pretty consistent with the giraffes and several species of monkey, like the Colobus. Oh and the ring-tails always seem to have a baby or young adult when I visit (granted it's been half a year...)
At Cotswold Wildlife Park: Siamangs, Morlett's Crocodiles and White Lipped Peccaries have all been prolific breeders. ( But all the peccaries have left now!)
Dortmund Zoo has outstanding success with Giant Anteaters (with the majority of the European population born here), Tamanduas, Malayan Tapir, some small cats like Oncilla and Jaguarundi, South American fur seals and of course giant otters.
Jersey Zoo: Sumatran Orangutans Mountain Chickens Mallorcan Midwife Toad Andean Bears (A few years ago now) and recently Asian Short Clawed Otters
Linton Zoo - . African Lions (Many Generations born since 1970 having gone all around the world) . Same to be said with African Leopards . Brazillian Tapir - 11 calves from one pair and still going! . Southern Ground Hornbill (First European Bred) . Binturong - Many awards have been won for breeding. Others to be mentioned: . Sulacta Giant Tortoise . Amur Tiger (3 litters) . Parma Wallabys . Mongoose Lemur, White Collared Lemur . Many Owl species, most have chicks most years . Grevys Zebra, 2 or 3 calves at least.
I'll say elephants for Chester and for long term breeding, ring-tailed lemur. They have bred each year since 1974, a total of 280 babies.
