Arctic Tern (Sterna paradisaea) a medium seabird around a foot in length, and a wingspan of around 30 inches, has a long pointed tail when it flight displays a fork. They have black caps which extend up the back of their short necks, then come around the sides of their heads right under their eyes before meeting the top of their short (for a tern) orange beaks. Their backs are a medium gray, while their breast are white. Arctic Terns also have short legs and webbed feet.
Arctic Terns have shorter beaks for their family because they spend more time in colder climates and beaks act as a heat sink.
Arctic Terns are more like polar terns. They nest in Alaska before flying back to Antarctica for winter. Some even circumnavigate Antarctica before making their way back up to Alaska for the northern summer, flying over 40,000 miles in a year. Making them the furthest traveling regularly migratory animal.
During their migration between the poles they stick to the open water, being rarely seen from land.
