Migratory birds and whales confused by warming

Birds, whales and other migratory creatures are suffering from global warming that puts them in the wrong place at the wrong time, Reuters reported a UN official as telling climate talks on Monday.
A warmer climate disrupts the biological clocks of migratory species including bats, dolphins, antelopes or turtles, said Lahcen el Kabiri, deputy head of the U.N.’s Bonn-based Convention on Migratory Species.
"They are the most visible warning signs — indicators signalling the dramatic changes to our ecosystems caused in part by climate change," he told delegates.
