Birds in France slower than climate change 法鳥類反應追不上全球暖化

From AFP:
The habitats of wild bird species are shifting in response to global warming, but not fast enough to keep pace with rising temperatures, according to a study released Wednesday.

Researchers in France also found that the delicate balance of wildlife in different ecosystems is changing up to eight times more quickly than previously suspected, with potentially severe consequences for some species.

"The flora and fauna around us are shifting over time due to climate change," said lead author Victor Devictor, a researcher at the French National Museum of Natural History.

"The result is desynchronisation. If birds and the insects upon which they depend do not react in the same way, we are headed for an upheaval in the interaction between species," he explained in a telephone interview.

These "mismatches" are likely to become greater over time, and could eventually threaten some birds with extinction, he added.

The study showed that the geographic range of 105 birds species in France -- accounting for 99.5 percent of the country's wild avian population -- moved north, on average, 91 kilometres (56.5 miles) from 1989 through 2006.

Average temperatures, however, shifted northward 273 kilometres (170 miles) over the same period, nearly three times farther.

It would be interesting to have some ides re changes in this part of the world; will surely include montane birds moving upwards/becoming scarcer or locally extinct [I've wondered re babax, if nos have fallen; Ba Bao Shan, say, could be interesting here].
