MARCORDES, B. et al. (2020)

Regional Collection Plan of the EAZA Waterfowl and Pelecaniformes Taxon Advisory Group

344 Seiten. EAZA, Amsterdam.

Aus der Einleitung:

The need for a new Regional Collection Plan was also linked to the outcome of the report ‘Future prospects of commonly kept pinioned bird species in EAZA collections’ (Dekker, 2016). The report made clear that waterfowl collections are clearly impacted by the legislative restrictions and/or institutional ambitions to work towards the EAZA Standards (EAZA, 2014) and move away from pinioning versus the growing legislative limitations towards pinioning. For that reason clear guidance from the TAG isneeded regarding priority species.

EAZA members are expected to follow up on the EAZA position statement on ‘Intentional Breeding for the Expression of Rare Recessive Alleles’(2013)for their waterfowl collection, and are encouraged to phase out any color mutations in their collections(e.g. white Mandarin ducks). As some of the duck, goose species hybridize rather easily, special attention is needed to prevent this.

The TAG is covering 240 species falling under different taxonomic groups (varying from Anatidaet o Prodicipedidae and Procellariidae). The taxonomy used is as proposed by the Handbook of the Birds of the World and BirdLife International “Illustrated Checklist of the Birds of the World Vol. 2” (del Hoyo &Collar, 2016).

A total of 54taxa are the subject of this RCPand have been discussed individually. With the main focus on threatened waterfowl species.

DE WIT, P. et al. (eds. 2021)

EAZA Penguin Taxon Advisory Group - Regional Collection Plan.

First Edition.EAZA Executive Office, Amsterdam.

Aus der Einleitung:

The EAZA Penguin TAG encourages all EAZA penguin holders to contribute through concreteconservation education activities (as indirect conservation role). Holders are encouraged to educate thepublic on:

  • The status of penguins e.g. 10 of 18 species declining, 10 of 18 species threatened;
  • The threats to penguins (in general and for specific species) e.g. conflict between fisheries and penguin colonies, impact climate change, petroleum discharge, risk/consequencesinvasive/introduced predators, infections and trade in wild penguins to meet demands of unscrupulous zoos and private collectors;
  • The need to conserve penguins in the wild and to protect their natural habitat;
  • How can we help?  Education around behaviour change –as a tourist to penguin areas,as a consumer, plastic use,etc.

The EAZA Penguin TAG also encourages all penguin holders to fundraise for any prioritized conservation projects either linked to the penguin species they keep orre-directed to aproject for a more threatened penguin species not kept in human care.The TAG will make sure a list of prioritized conservation projects will be made available and/or circulated annually.

REITER, J. & WINKLER, A. (2015)

Fossa Cryptoprocta ferox International Studbook (ISB) 2014.

73 Seiten mit Fotos, Grafiken und Tabellen. © Zoo Duisburg

Introduction (auszugsweise):

The data reported in this studbook are current through 31 December 2014. On that date the historical population was 144.108.61 (313) animals and the living population was 78.58.0 (136) animals in 57 institutions. This latter number includes:
1.1.0 (2) animals in 1 institution in the Asian region;
3.2.0 (5) animals in 1 institution in the African region;
37.24.0 (61) animals in 27 institutions in the European region; and
37.31.0 (68) animals in 28 institutions in the North American region.

Zoo Duisburg not only manages the global population of the fossa but also the European zoo population that started in 1972 with Zoo Basel, Switzerland, as the very first holder. The first offspring in the zoo world was recorded two years later at Montpellier Zoo, France. The species is difficult to breed, so breeding successes were and still are limited and the population only slowly increased since the 1970s. Over the years several animals have been exchanged between Europe and North America to improve the genetics of the respective population.

The first fossa recorded in North America was at the National Zoo in Washington in 1954. However, the species has been exhibited consistently only since 1985, when a male and a female were imported to San Diego from Zoo Basel. This pair produced the first zoo-born fossa in North America in 1989. Since then, over the last 25 years, the North American fossa population has continued to grow in size more rapidly than the European one, not only due to zoo breeding but also due to animals that occasionally came into the managed population from private institutions. Ueno Zoological Garden in Japan started to keep fossas with a pair in 2010, as the only holding institution in the Asian region so far. Five animals are listed for the capital zoo of Antananarivo on Madagascar, where in 2011 the first captive-born fossa could be recorded for this region.

The global captive population of the fossa has potential to develop further, but also faces certain limitations. The age structure is not well-dispersed throughout the various age classes, with some of the latter being regionally empty, nor is there an even sex ratio. Especially concerning is the few number of younger individuals in the population, most notably among the females. This population should thus focus on producing offspring at regular intervals in order to maintain a more even distribution of reproductive age animals to insure further breeding successes in the future. The population must also aim at recruiting new holders to increase the holding capacity and to be able to accommodate further offspring. The gene diversity can only be increased with additional potential founder animals and by equalizing founder representation (by breeding animals with the lowest mean kinships).

There are currently several fossa conservation and research activities taking place. In 2014, a cooperation between the Fossa Fund (initiated in 1994 by Zoo Duisburg in order to support conservation and research activities within the species’ natural habitat on Madagascar) and the German NGO "Chances for Nature" started.

National Studbook Four Horned Antelope (Tetracerus quadricornis).

Hrsg.: Wildlife Institute of India, Dehradun and Central Zoo Authority, New Delhi.TR.No2018/02.
109 Seiten.

Conclusions and Recommendations:

Four horned antelopes continue to face threats to their longterm survival in their natural habitats across their distribution range and are accordingly listed as Vulnerable in the IUCN Red List of Threatened Species and in the Schedule I of the Wildlife Protection Act of India. The threats faced by the species remain operational and the populations across their range are showing declining trend. Maintenance of demographically stable and genetically viable ex-situ populations is thus crucial for ensuring the continued survival of the species. The captive population in Indian zoos is characterized by a declining trend (λ = 0.0676). The population remains biased towards females with a limited number of proven breeders, though a large proportion belong to reproductively active age classes. It retains approximately 93% genetic diversity introduced by 16 founders. Values of population mean inbreeding and mean kinship indicate that specimens are unrelated to each other; however, the founder genome is poorly represented with the population containing genetic diversity of approximately only 8founder animals. Population simulations run using PMx software indicate that supplementation with one effective founder every two years and increasing the population growth rate to 1.0252and population size to 200 specimens in Indian institutions can ensure that the population remains viable over the next 100 years. The captive population of Four horned antelope in Indian zoos therefore requires intensive management efforts towards ensuring achievement of ex-situ conservation goals to address the following concerns:

  1. Additional housing facilities are requiredto ensure availability of adequate space for holding the additional number of specimens needed for maintaining a genetically viable and demographically stable population.
  2. The wild origin specimens that are currently present in the population should be assessed for relatedness using appropriate molecular genetics tools. The assessment so carried out should form the basis for deciding mate choice.
  3. Issues that limit optimum reproductive performance of the captive population viz. housing and husbandry practices and keeping of unpaired animals need to be addressed for ensuring effective population growth.

PARKES, S. (2011)

European Studbook for Douroucouli 2007-2010, Aotus lemurinus griseimembra & Aotus azarai boliviensis. Current until 31.12.10.

107 Seiten. Marwell Wildlife, Winchester.


The Studbook provides a full overview of the living population, births, deaths and transfers over period 2007-2010, and also a full historical listing (a printed version of this list is only available on request). All animals registered in the studbook have been issued with a unique studbook number. Even if stillborn, animals will still be entered into the database as this is useful for reproductive analysis and also future demographic analysis. Temporary numbers mark animals of completely unknown origin and/or destiny, or animals where further investigation is needed.

The total number of douroucouli in captivity as reported to the studbook keeper by 31st December 2010 was Aotus lemurinus griseimembra 33.41.11 (85) in 19 institutions and Aotus azarae boliviensis 15.14.2 (31) in 12 institutions. These include animals in EAZA and non EAZA institutions and private holders.

DMOCH, R. (1997)

Husbandry, breeding and population development of the Sri Lankan Rusty‐spotted cat Prionailurus rubiginosus phillipsi.

International Zoo Yearb. Volume 35: 115-120.


In September 1975 Frankfurt Zoo received 1.1 7 week‐old Rusty‐spotted cats Prionailurus rubiginosus phillipsi from Sri Lanka. As at 31 December 1995 16.19 animals, all descended from this pair, were listed in the international studbook at eight collections (Dmoch, 1996). Between 1976 and 1994 77 Rusty‐spotted cats were born in captivity and breeding data reveal that: sexual maturity is reached within the first year; mean litter size is 1–3 (n= 58); mean time of first mating is 7–8 days after introduction (n= 78); mean mating activity period is 5–7 days (n= 49); gestation period is between 67 and 71 days (mean 69 days, n= 22). Breeding ceased in 1989 at Frankfurt Zoo and in 1991 at Cincinnati, which could indicate an inbreeding depression. This paper describes the diet, growth and development, veterinary care, husbandry and behaviour of the species.
