Winter release and management of reintroduced migratory Whooping Cranes Grus americana [PDF]

Bird Conservation International, 2009
SummaryFrom 2001 to 2005, 71 costume-reared juvenile Whooping Cranes Grus americana were led by ultralight aircraft from Wisconsin to a winter release site on the west-central Gulf Coast of Florida. A strategy was developed and implemented to maximize first winter survival while preventing exposure to non-costumed humans and tame Sandhill Cranes ...

Climate‐related drivers of migratory bird health in the south‐central USA

Biological Reviews, Volume 100, Issue 3, Page 1272-1293, June 2025.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

加拿大鹤代养美洲鹤

野生动物学报, 1989
以加拿大鹤（Grus canadensis tabida）作义亲代养美洲鹤（Grus americana）的试验最早于1950年,由萨斯卡切丸（Saskat—chewarn）自然博物馆馆长弗里德·巴德（Fred·E·Bard）所设计和试行。五十年代及六十年代初期,国际上普遍对美洲鹤的濒危表示忧虑。要想挽救它恐不能单靠其自然繁殖,而必须借人为的努力,拾取一定量的野生卵,孵化并育出健壮雏鸟,而后释放到野外以增加野生种群数量或以此建立新的种群。为进行义亲代养试验,必须首先研究二种鹤的生态及其相互关系 ...

Same‐sex partnerships in birds: a review of the current literature and a call for more data

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
Same‐sex sexual behaviour (SSB), encompassing actions such as courtship, pair bonding, and parenting between individuals of the same sex, has been observed across numerous taxa, including birds. Yet despite its widespread occurrence, SSB remains poorly understood, often dismissed as maladaptive or the result of errors in sex discrimination.

Long-term migratory alterations to whooping crane arrival and departure on the wintering and staging grounds

Endangered Species Research
Climate change can result in alterations to avian behavior, particularly in migratory species. We assessed long-term changes in the endangered whooping crane Grus americana migration phenology in response to temperature, precipitation, and other ...

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.

Translocation experiment of taiga bean geese Anser fabalis provides evidence for oblique social learning of moult migration

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
While there is ample evidence supporting genetic control of migratory behaviour in short‐lived passerines, long‐lived social species have been assumed to rely solely on cultural inheritance of migratory routes. Evidence from experimental studies supporting this idea is scarce.
