卡纳比的黑凤头鹦鹉是一种濒危物种，在澳大利亚西南部的范围和数量都急剧下降。在2009年10月至2010年3月期间，该物种在其主要繁殖区之一可能爆发疾病，并暴露在极端炎热的天气和严重的局部冰雹风暴中。此外，与机动车辆的碰撞对该物种构成越来越大的威胁。所有这些随机事件都导致了许多死亡。像卡纳比的黑凤头鹦鹉这样形成大群的物种特别容易受到局部事件的影响，如冰雹风暴、传染病和与机动车辆的碰撞。极端温度可能对集群和非集群物种产生重大影响。对西澳大利亚西南部气候变化的预测是，极端天气事件的频率将增加，如热浪和严重的冰雹风暴。更多的这种性质的事件对卡纳比的黑凤头鹦鹉的影响进行了讨论。
Carnaby's Black Cockatoo is an endangered species which has undergone a dramatic decline in range and abundance in southwestern Australia. Between October 2009 and March 2010 the species was subjected to a possible outbreak of disease in one of its major breeding areas and exposed to an extremely hot day and a severe localized hail storm. In addition, collisions with motor vehicles are becoming an increasing threat to the species. All of these stochastic events resulted in many fatalities. Species such as Carnaby's Black Cockatoo which form large flocks are particularly susceptible to localized events such as hail storms, contagious disease and collisions with motor vehicles. Extreme temperatures may have major impacts on both flocking and non-flocking species. Predictions of climate change in the southwest of Western Australia are that there will be an increased frequency of extreme weather events such as heat waves and severe hail storms. The implications of more events of this nature on Carnaby's Black Cockatoo are discussed.
