Wading Out?

Migratory, wading birds have a risky life-style and are very vulnerable to environmental changes and there arehttp://www.theguardian.com/environment/2014/jul/30/wetland-bird-survey-wading-birds-britain-climate-change recent indications of dramatic declines in populations of these animals in the UK (http://www.theguardian.com/environment/2014/jul/30/wetland-bird-survey-wading-birds-britain-climate-change). One could, to some extent, reverse the calculation and suggest that the population declines indicate that recent environmental changes are substantive and challenging.
