This seems to be standard fare from the BBC - misleading headline about declines in bird populations being due to climate change, while brushing over the many other causes of declines - some of which could be tackled much more easily than climate change.
Not just the BBC. The State of Nature report skips most of the causes for biodiversity decline that I see on a day to day basis and include some as headlines which have marginal impacts (to date in the UK) from my experience....
It is all political and the ability to deliver clear concise messages to the public making maximum immediate impact is lost as a result.
"The main causes of these declines are
clear, as are many ways in which we
can reduce impacts and help struggling
species. The evidence from the last
50 years shows that on land and in
freshwater, significant and ongoing
changes in the way we manage our land
for agriculture, and the effects of climate
change, are having the biggest impacts
on our wildlife."
Let's face it, we have even seen censorship of some causes such as pets on this forum as well.
All the best
