The article highlights the results of a study conducted by a team led by Tim H. Sparks, an ecologist at the Natural Environment Research Council in Monks Wood, England, on the arrival and departure dates of thirty-three migrant bird species. Birds returning from a winter's retreat are showing up in England earlier and earlier each spring as a result of global warming, a new study confirms. Unexpectedly, populations in decline show a less pronounced shift than thriving ones do, sparking fears that ecologists have underestimated the effect of rising temperatures on migratory birds.
