Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated. © 2020 The Wildlife Society.

浆果重要吗？狼准备在明尼苏达州北部的浆果中撒布

狼（Canis lupus）主要通过捕捉哺乳动物的猎物并将尸体的残骸通过它们的嘴或胃送到巢穴或会合地点的幼崽来提供幼崽。2017年8月，我们在美国明尼苏达州大旅行者生态系统的一个会合地点观察到一只成年狼将野生蓝莓（Vaccinium spp。）向幼崽反哺，这是唯一已知的狼为幼崽提供野莓的观察结果。这一观察结果与大旅行者生态系统的其他证据相结合，表明野生浆果可能是南方北方生态系统中狼更有价值的食物来源。©2020野生动物协会。
