Over 40 years of data show that migratory birds have been getting smaller as the climate warms. The birds' body masses, leg bone lengths, and overall body sizes all decreased, while their wingspans increased, likely linked to rising temperatures.
A new analysis of a dataset of over 70,000 North American migratory birds found that body size decreased in all 52 species, with statistically significant declines in 49 species, while wing length increased in 40 species. The study suggests that warming temperatures may be causing these changes as an adaptation to climate change.
Researchers from Kiel University found that the invasive American slipper limpet is not the main cause of European oyster population decline in the North Sea.
