🐦Black-headed Gull

Chroicocephalus ridibundus (Linnaeus, 1766)

Hættemågen (latin: Chroicocephalus ridibundus) er Danmarks mest almindelige måge. Den er endvidere udbredt i resten af Europa, Asien og i kystegne i det østlige Canada. Hovedparten af bestanden er trækfugle, der trækker mod syd om vinteren, men en del af hættemågerne er dog standfugle. De danske hættemåger trækker i juli typisk til Vesteuropa (enkelte helt til Nordafrika) for at fælde og overvintre. Hættemågen yngler i kolonier i søer og moser eller på småholme ved kysten. Herudover træffes de også i f.eks. byområder og på marker og enge, når yngletiden er overstået. Den er regnet som en truet art på den danske rødliste 2019.
