http://news.bbc.co.uk/earth/hi/earth_news/newsid_8560000/8560694.stm Climate linked to smaller birds By Matt Walker Editor, Earth NewsSongbirds in the US are getting smaller, and climate change is suspected as the cause.

This shrinkage has occurred within just half a century, with the birds thought to be evolving into a smaller size in response to warmer temperatures. <snip> =============================== www.birding-aus.org birding-aus.blogspot.comTo unsubscribe from this mailing list, send the message: unsubscribe (in the body of the message, with no Subject line) to: =============================== |
