Vulnerable Birds in Bremer County
Highly and moderately vulnerable birds may lose more than half of their current range—the geographic area where they live—as they are forced to search for suitable habitat and climate conditions elsewhere.
Below, find out which of the birds that nest or spend the winter in your area are most vulnerable across their entire range. Some birds may lose range outside of your state, making the protection of their current habitat in your area even more important.
How Will the Song Sparrow's Range Be Affected in Bremer County?
Rising temperatures and shifting weather patterns affect birds’ ability to find food and reproduce, which over time impacts local populations, and ultimately continent-wide populations, too. Some species may even go extinct in your state if they cannot find the resources they need to survive and raise their young.
Select a warming scenario to see how this species’ range will change under increased global temperatures.
Reducing warming makes many types of birds found in Bremer County less vulnerable.
Without immediate, urgent action to reduce carbon emissions, global temperatures could rise by 3.0°C in the coming decades, endangering birds in your area. The threat is drastically reduced if we curb greenhouse gases and we limit warming to 1.5°C, giving the same birds a chance to not only survive but thrive.

Climate Threats Facing Birds and People in Bremer County
Heavier precipitation has increased the frequency, distribution, and intensity of floods along the Missouri and Mississippi rivers, damaging homes, infrastructure, and critical bird habitat. Rising temperatures will exacerbate droughts and reduce crop yields. In the coming decades, Iowa will likely experience more intense droughts and more frequent extreme heat days that threaten communities, especially vulnerable people such as children, the elderly, the sick, and the poor.
The same climate change-driven threats that put birds at risk harm people, too. Hover over or tap an area on the map to see specific threats that will affect that area as warming increases.
