Great Tits Cope Well with Warming….

May 9, 2008

The blog title above is the actual headline from a BBC News article. The discussion is about how some British birds are coping (or not coping for that matter) with climatic changes. The Great Tit, for example is doing quite well, adapting to the earlier arrival of its Winter Moth caterpillar food by laying its eggs earlier. Thus the chicks have abundant food when they hatch. (from the article, emphasis added)

At least one of Britain’s birds appears to be coping well as climate change alters the availability of a key food.

Researchers found that great tits are laying eggs earlier in the spring than they used to, keeping step with the earlier emergence of caterpillars.

Writing in the journal Science, they point out that the same birds in the Netherlands have not managed to adjust.

Understanding why some species in some places are affected more than others by climatic shifts is vital, they say.
