  • Citizen science is contributing much data for scientific research, especially through birding-related projects like eBird and the Christmas Bird Count.
  • Scientists estimate that plastic will be found in 99% of seabirds by 2050. It already affects 60% of species; the number of individuals affected rose from <5% in 1960 to 80% by 2010.
  • Many birds may lose parts of their ranges due to climate change, and conservation planning needs to account for shifting ranges.
  • Common Loons return to the same wintering sites year after year.
  • White-tailed Eagles avoid large bullet fragments during consumption of carcasses, an important finding in support of nonlead ammunition. 
  • Scientists are trying to bring back the endangered Attwater's Prairie-Chicken, but success is limited due to numerous factors, from fire ants to floods. Currently the population stands at 104 birds.
