Birds and birding news
  • For the sixth year in a row, there has been a mass die-off of seabirds in Alaskan waters, this time near Nome. Most have been murres or Horned Puffins, and many are emaciated; it is unclear if this is due to disease or an inability to find food.
  • Swifts make vesper flights twice a day, which they use to orient themselves.
  • Artificial lighting disrupts birds' sleep at night, and the lack of sleep may affect their ability to forage during the day.
  • The timing and route of Rufous Hummingbirds during migration varies by age and sex.
  • The EU has threatened to fine France if it does not end the practice of hunting birds with glue sticks.
