野生动物学报, 1986 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 ...

Avian Conservation and Ecology, 2013 Birds are vulnerable to collisions with human-made fixed structures. Despite ongoing development and increases in infrastructure, we have few estimates of the magnitude of collision mortality.

Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Ibis, Volume 168, Issue 1, Page 216-229, January 2026.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 ...

Integrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.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 ...

Annual survival rates of migratory shore and upland game birds
Wildlife Society Bulletin, 2016 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 ...

Persistent Genomic Erosion in Whooping Cranes Despite Demographic Recovery
Molecular Ecology, Volume 34, Issue 23, December 2025.ABSTRACT Integrating in‐situ (wild) and ex‐situ (captive) conservation efforts can mitigate genetic diversity loss and help prevent extinction of endangered wild populations. The whooping crane (Grus americana) experienced severe population declines in the 18th century, culminating in a collapse to ~20 individuals by 1944.

Breeding home range selection of Eastern Population sandhill cranes across the boreal forest
The Journal of Wildlife Management, Volume 89, Issue 8, November 2025.We evaluated breeding home range habitat selection of sandhill cranes (Antigone canadensis) in the boreal forest of eastern Canada. Overall, we found that sandhill cranes selected breeding home ranges with greater proportions of wetlands, cropland, and recently disturbed forest.

Characterization of visual pigments, oil droplets, lens and cornea in the whooping crane Grus americana [PDF]
Journal of Experimental Biology, 2014 Vision has been investigated in many species of birds, but few studies have considered the visual systems of large birds and the particular implications of large eyes and long-life spans on visual system capabilities. To address these issues we investigated the visual system of the whooping crane Grus americana (Gruiformes, Gruidae), which is one of ...

Can edge AI mitigate environmental effects on camera trap performance?
Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.A camera trap enabled with edge artificial intelligence (AI) mitigated the effects of increased air temperature on the probability of false positive detections, but at the cost of an increased probability of missed detections. Other environmental variables affected camera trap performance differently, suggesting the need to account for camera trap ...
