We’ve all heard of the Arctic Tern, one of the world’s most impressive migratory birds. Known for its remarkable 11,000-mile journey from the Arctic to the Antarctic and back again, this intrepid species is truly a marvel of nature. But what else do we know about this incredible creature? Here, we explore its breathtaking migration, unique physiology and fascinating behavior.
The Arctic Tern is a sight to behold with its sleek black head and wings, white underbody, orange beak, and legs. It can be found in coastal waters across Europe, North America and Australia during the warmer months when it travels south in search of food. Each year it undertakes an epic 11,000-mile migration between the icy climes of the Arctic and Antarctic circles, soaring over oceans and continents before settling in for breeding season. This makes them amongst the longest-distance migrants on Earth — quite an accomplishment for such a small bird!
Despite their diminutive size, Arctic Terns are incredibly hardy creatures that can survive extreme weather conditions throughout their long journey. They have adapted special physiological features which help them to conserve energy while they fly — such as short wingspans which reduce drag — as well as highly efficient navigation systems which enable them to find their way home each year without fail. In short, these feathered adventurers are true masters of survival!
Migration Habits
The Arctic Tern is a masterful navigator. It has the longest migration of any species on Earth, traveling from the icy Arctic to the warmth of Antarctica and back again in an astonishingly epic journey. Flying up to 50,000 miles each year, it circles the globe twice, soaring across oceans and continents alike with ease. This remarkable bird is one of nature’s true champions when it comes to migrating long distances. The sheer determination and stamina shown by the Arctic Tern is nothing short of astounding. With such strength and resilience, it’s no wonder that this species continues to thrive despite its arduous travels every year. Transitioning now to its breeding behavior…
Breeding Behavior
Arctic terns breed in colonies, often located on rocky islands and coastal cliffs. The breeding season typically occurs between May and August. During this time, courtship rituals involve saluting (head bowing), calling, and displaying their bright red bill, legs, and feet.
Here are 4 important facts about Arctic tern breeding behavior:
- Arctic terns are monogamous and mate for life.
- Both the male and female Arctic tern help in building the nests with grasses, feathers, mosses, lichens and twigs.
- They lay two to three eggs that are incubated by both parents for up to 24 days until they hatch.
- Once hatched, chicks fledge in 24-25 days after hatching.
Both parents provide food to their young until they can feed themselves at around 40 days old after which they become independent of their parents. With this strong parental care provided by both mates, Arctic terns have a high success rate when it comes to raising chicks. This transitioning into independence sets the stage for the next step – diet and feeding habits of the species.
Diet And Feeding Habits
| The Arctic Tern is a champion when it comes to eating, as it has no rival when it comes to finding food. This bird’s appetite is voracious and its ability to find food is unmatched. It can search for food in some of the most inhospitable places on earth! | Food Type | Location |
|---|---|---|
| Small Fish & Krill | Ocean Surface | |
| Insects & Amphipods | Freshwater Lakes & Ponds | |
| Berries & Fruits | Feeding Grounds Near Beaches |
The Arctic Tern starts its feeding by diving headfirst into the water, often reaching depths of up to 15 feet. When it reaches the bottom, it will swim around searching for fish and other small prey. It will also swoop down from the sky onto land to snatch up insects, berries, or fruits. The Arctic Tern will also use its beak to grab food off of rocks or vegetation in shallow waters. All in all, this bird has a very varied diet that enables it to survive even in extreme environments with limited resources.
With sharp eyesight and an impressive wingspan, the Arctic Tern is able to deftly maneuver over land and sea in order to find food. Its speedy flight allows it to cover vast distances quickly, enabling it to hunt more efficiently than many other birds of similar size.
