In recent years, cormorants have been observed migrating further north than ever before. In some cases, they are even establishing new breeding colonies in areas that were previously too cold for them to survive. This northward shift is likely due to the fact that cormorants are able to find more food and better nesting sites in these areas.
Climate change is also causing cormorants to change the timing of their migrations. They are now migrating earlier in the spring and later in the fall than they did in the past. This is likely due to the fact that cormorants are trying to avoid the extreme weather conditions that are becoming more common in the spring and fall.
The changes that cormorants are making to their migration routes are a sign that they are adapting to climate change. However, it is important to note that these changes are not always easy for cormorants. They can face many challenges, such as finding new food sources and nesting sites, and avoiding predators.
Despite the challenges, cormorants are showing that they are resilient creatures that are able to adapt to changing conditions. By making changes to their migration routes, cormorants are increasing their chances of survival in a changing climate.
