With climate change, US ecosystems have shifted hundreds of miles north.

Researchers in Nebraska analyzed 46 years’ worth of bird data collected for the North American Breeding Bird Survey, a program designed to track bird populations. The survey discovered the areas where specific species of birds lived had changed across the United States. Researchers found that coinciding with climate change, the habitats of birds have shifted. The northernmost ecosystem shifted more than 366 miles north – the length of an entire state. The southernmost boundary moved about 160 miles northward. The northernmost ecosystem shifted more than the southernmost area because of a well-known phenomenon known as Arctic amplification. Arctic amplification, or polar amplification, is a phenomenon that any change in the balance of solar radiation across the plant tends to produce a larger change near the earth’s

See the intercontinental path of two birds on their epic migration from Europe to Africa

The guys over at 422 South have done it again providing us a wonderful “data-visualization” of the migratory path of the European honey buzzard.  The European honey buzzard, also known as the pern, migrates every year from Europe to the warmer coasts of Africa where it spends the winter months soaking in the warm sun and sipping on drinks with little umbrellas in them.  The visual above shows the remarkable flight paths of two such honey buzzards, a male and a female, between Fall 2010 and Spring 2011.  Both birds' southward migration took them from the Veluwe forest in the Netherlands to the warmer weather on the African coast (Liberia, Ghana, and Cameroon).  After wintering in Africa, both birds flew back to the Veluwe forest (the
