鸟类有麻烦了，但是你可以帮助它们

鸟类有麻烦了，但是你可以帮助它们

Two-thirds of birds in North America are at risk due to warming temperatures and human impact on the planet.

由于全球变暖和人类对地球的影响，北美三分之二的鸟类正处于危险之中。

Scientists used 140 million records from field biologists and bird watchers to outline where 604 bird species live now. Then then used climate models to forecast how each species' range will likely shift as climate change and other human elements continue to have an impact.

科学家们从野外生物学家和鸟类观察者那里收集了1.4亿条记录，来勾勒出604种鸟类现在生活的地方。然后利用气候模型预测，随着气候变化和其他人为因素继续产生影响，每个物种的活动范围可能会发生怎样的变化。

The report found that 64% of species (389 of 604) were moderately or highly vulnerable to climate change. Vulnerability often depended on habitat. For example, 100% of Arctic bird species, 98% of boreal forest birds, 86% of western forest birds and 78% of waterbirds were vulnerable to climate change. The least vulnerable birds included those in marshlands (41%) and urban/suburban areas (38%). However, even in groups that were not as susceptible, more than a quarter were considered climate-vulnerable.

报告发现，64%的物种(604个物种中有389个)对气候变化具有中度或高度脆弱性。脆弱性往往取决于生境。例如，100%的北极鸟类、98%的北方森林鸟类、86%的西部森林鸟类和78%的水鸟易受气候变化的影响。最不脆弱的鸟类包括沼泽地鸟类(41%)和城市/郊区鸟类(38%)。然而，即使在不那么敏感的群体中，超过四分之一的人也被认为是易受气候影响的。

The report studied climate-related impacts such as sea level rise and lake level changes, urban land use changes, cropland expansion, drought, extreme spring heat, fire weather and heavy rains.

该报告研究了气候相关影响，如海平面上升和湖泊水位变化、城市土地利用变化、农田扩张、干旱、极端春季高温、火灾天气和暴雨。

How you can help

The purple finch, which is actually more of a rose color, is a common sight at backyard feeders. Audubon's tool pinpoints the effects of climate on birds in your area and then shows how their range could be effected in different scenarios.

Along with the report, Audubon offers a ZIP-code based tool so you can see which impacts from climate change are expected in your area and which bird species will be affected.

除了这份报告，Audubon还提供了一个基于邮政编码的工具，这样您就可以看到气候变化对您所在地区的影响以及哪些鸟类将受到影响。

"We already know what we need to do to reduce global warming, and we already have a lot of the tools we need to take those steps. Now, what we need are more people committed to making sure those solutions are put into practice," said Renee Stone, vice president of climate for the National Audubon Society. "Our elected officials at every level of government must hear from their constituents that this is a priority. Audubon is committed to protecting the places birds need now and in the future and taking action to address the root causes of climate change."

“我们已经知道我们需要做什么来减少全球变暖，我们已经有了很多采取这些步骤所需的工具。现在，我们需要的是更多的人致力于确保这些解决方案得到实施。“我们各级政府的民选官员必须从选民那里听到，这是一项优先任务。奥杜邦致力于保护鸟类现在和将来需要的地方，并采取行动解决气候变化的根本原因。”

You can help our flying friends and attract more birds to your yard by adding native trees, bushes and other plants that offer food and protection, as MNN's Tom Oder explains in detail. But Audubon also outlines two bigger-picture ways you can help birds survive through your actions at home and by advocating for the spaces they call home:

你可以帮助我们的飞行朋友，并吸引更多的鸟类到你的院子里来，通过添加本地的树木，灌木和其他提供食物和保护的植物，MNN的Tom Oder详细解释道。但奥杜邦还概述了两种更好的方法，你可以帮助鸟类通过你在家里的行动和通过倡导他们称之为家的空间来生存:

1. Reduce energy use at home and ask elected officials to support energy-saving policies.

1. 减少国内的能源使用，并要求当选官员支持节能政策。

2. Ask elected officials to expand clean energy development – like solar or wind power.

2.要求民选官员扩大清洁能源的发展——比如太阳能或风能。
