New Delhi: The high-altitude species are now finding it difficult to cope up with the sudden change in seasonal events of their native areas.
In the past few decades, climate change has induced major ecosystem shifts in various parts of the Earth. Caspian terns are the recent one to under went wide scale species shift.
This year, the seabird is found nesting 1,000 miles further north than the species has been previously recorded. The habitat-shift of Caspian terns are monitored by a team of scientist with Wildlife Conservation Society.
"What we saw this season for Caspian terns is another example of the fragility of the Arctic system," Peter Zahler, WCS regional director,said in WCS news release. "New patterns are starting to take hold in an environment that is dynamic and reinventing itself in the context of a new warmer climate."
The Caspian tern is the largest tern species and are mainly found in Washington state. As the landscape of Arctic are largely driven by climate change, the unusual warm temperature are allowing many temperate species to expand into previously uncharted territories.
