Effectiveness of Key Biodiversity Areas in representing global avian diversity
Abstract Key Biodiversity Areas (KBAs) are the largest and most complete network of significant sites for the global persistence of biodiversity. Although important sites for birds worldwide have been relatively well assessed, a key question is how effectively the global KBA network represents avian diversity.

Annual survival rates of migratory shore and upland game birds
Band recoveries from hunted populations are widely used to estimate survival and harvest rates. We used long‐term (1950–2010) band‐recovery data from the United States and Canada to estimate average survival and recovery rates for juvenile and adult ...

Farmers' tolerance for crop damage caused by wildlife: the role of compensation
Compensation is a common strategy to alleviate financial losses caused by wildlife, but its effects on farmers' tolerance towards damage to crops caused by wildlife are poorly understood. To address this knowledge gap, we conducted semi‐structured interviews in three areas in and around biosphere reserves in Sweden and Germany to examine farmers ...

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

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 ...

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 ...

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.

Whooping crane use of riverine stopover sites.
Migratory birds like endangered whooping cranes (Grus americana) require suitable nocturnal roost sites during twice annual migrations. Whooping cranes primarily roost in shallow surface water wetlands, ponds, and rivers.

Waterfront property owners' shoreline preferences amid salt marsh to mangrove transitions
Abstract We examined the influence of mangrove encroachment into salt marsh areas along the northern Gulf of Mexico (USA) on waterfront property owners' perceptions of coastal health and preferences for shoreline management. Using mail‐in and online surveys, we targeted over 3000 waterfront property owners across four jurisdictions experiencing or ...
