温哥华岛的鸟因息地丧失和竞争而处于危之中,需要老森林才能生存. Coastal screech-owls on Vancouver Island are endangered due to habitat loss and competition, needing old growth forests for survival.

据鸟类学家梅根·布尔斯介绍，温哥华岛上的沿海尖叫猫头鹰，作为濒危亚种，依赖沿海道格拉斯冷杉和加里橡树等原始森林生存。 Coastal screech-owls on Vancouver Island, a threatened subspecies, depend on old growth forests like coastal Douglas fir and Garry oak ecosystems for survival, according to ornithologist Megan Buers. 由于伐木、发展和与被禁猫头鹰的竞争,他们的人数已经下降,岛上东海岸的人口现在很少。 Their numbers have declined due to logging, development, and competition with barred owls, with populations now rare on the island’s east coast. 使用跟踪标签进行的研究显示,它们依靠密集的老生长区来捕猎小型哺乳动物、蜗牛、两栖动物和鱼类。 Research using tracking tags shows they rely on dense old growth areas for hunting small mammals, snails, amphibians, and fish. 比尔斯强调,恢复当地植物和猎物是恢复的关键,她认为,如果生境得到保护和恢复,该岛能够养活三到四倍其目前的猫头鹰种群。 Buers stresses that restoring native plants and prey species is key to recovery, and she believes the island could support three to four times its current owl population if habitats were protected and restored. 个人可以通过种植本地物种、保护枯树和安装巢穴箱来提供帮助。 Individuals can help by planting native species, preserving dead trees, and installing nest boxes.
