MULTIDISCIPLINARY APPROACH TO UNDERSTANDING THE POOR REPRODUCTION IN THE WHOOPING CRANE (GRUS AMERICANA) [PDF]
Reproductive success of the endangered whooping crane (Grus americana) maintained ex situ is suboptimal. The main goals of this multidisciplinary investigation are to advance the understanding of whooping crane reproduction and identify potential causes ...

Archive eggs: A research and management tool for avian conservation breeding
Worldwide, approximately 168 bird species are captive‐bred for reintroduction into the wild. Programs tend to be initiated for species with a high level of endangerment. Depressed hatching success can be a problem for such programs and has been linked to

Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...

Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

国际鹤类基金会(I.C.F),位于美国威斯康星州巴拉布市附近,建于1973年。我们应基金会主席乔治·阿其波博士的邀请,于1985年4月24日至6月11日到基金会考察学习。基金会占地面积150英亩,现有两处饲养场和一处育雏场,均供鹤类科学研究用。共饲养11种鹤类,近百只。其中世界濒危鹤类有美洲鹤(Grus americana)、丹顶鹤(Grus jaPonensis)、黑颈鹤(Grus nigricollis)、白鹤(Grus leucogeranus)、白枕鹤(Grus vipio)、肉垂鹤 ...
