The Arctic Tern (Sterna paradisaea) is an avian marvel known for its extraordinary migratory pattern that spans from the Arctic to the Antarctic and back each year. These small, slender winter birds, with an adult wingspan of about 75-85 centimeters, are readily identified by their distinctive black cap, bright red beak, and deeply forked tail. Their plumage is predominantly white and light gray, providing excellent camouflage against the ice and snow of their native habitats (Hatch, 2002). This intricate migration makes the Arctic Tern one of the longest-distance migrants in the animal kingdom (Egevang et al., 2010). 

Interesting Fact: Arctic Terns have one of the longest migrations of any animal, flying over 25,000 miles each year. This incredible journey ensures they see two summers annually, taking advantage of the abundant food resources available in both polar regions.

Despite their small size, Arctic Terns possess incredible endurance and adaptability that enable them to thrive in the harshest of environments. They breed in the Arctic regions during the summer, taking advantage of the continuous daylight for feeding and raising their young. As winter approaches, they embark on their monumental journey to the Antarctic, where they experience another summer. Arctic Terns enjoy more daylight than any other creature on Earth (Hatch, 2002). 

Their diet consists mainly of fish and small invertebrates, which they skillfully catch by plunge diving from flight. During the breeding season, they are fiercely territorial and will aggressively defend their nesting sites against intruders, including much larger predators (Egevang et al., 2010). If you’re lucky enough to spot an Arctic Tern during its transient stopovers or in its breeding grounds, you’re witnessing an extraordinary testament to the resilience and endurance of nature’s avian navigators.

Ross’s Gull, known scientifically as Rhodostethia rosea, is one of the most enchanting seabirds found in the Arctic. This small, delicate bird is characterized by its distinctive pinkish hue on the chest and a striking wedge-shaped tail, traits that make it easily recognizable even to novice birdwatchers.  

Typically found breeding in the high Arctic regions, Ross’s Gulls prefer the remote tundra for nesting. During the non-breeding season, these gulls migrate to the northernmost coasts of Canada, Greenland, and sometimes even reach as far as the British Isles. Their presence is a rare treat for bird enthusiasts and photographers alike, often leading to much excitement within the birdwatching community (Goss-Custard et al., 2006).  

Interesting Fact: The Ross’s Gull are named after the British explorer James Clark Ross, who first discovered them on an expedition to the Arctic in the 19th century.

Apart from their captivating appearance, Ross’s Gulls are also notable for their unique feeding habits. They primarily feed on small fish and invertebrates, which they pick off the surface of the water or catch mid-flight. This feeding behavior, combined with their graceful flight patterns, makes observing these birds an engaging experience.  

Regarding their conservation status, Ross’s Gulls are considered to be of least concern by the IUCN. However, their reliance on pristine Arctic environments makes them vulnerable to habitat changes brought on by climate change.

The Atlantic Puffin (Fratercula arctica) is a seabird instantly recognizable by its colorful beak and striking black and white plumage. These charismatic birds are often referred to as the “clowns of the sea” due to their distinctive appearance and playful behavior. Found primarily in the North Atlantic, they are migratory birds, breeding in large colonies on coastal cliffs and islands during the summer months. As winter approaches, Atlantic Puffins head out to sea where they spend the majority of their lives. 

Atlantic Puffins are skilled divers, using their wings to “fly” underwater while chasing after small fish, such as herring and sand eels, which make up the bulk of their diet. Their beaks are specially adapted for carrying multiple fish at a time, with backward-facing spines that prevent prey from slipping out. This unique feeding strategy allows them to efficiently bring food back to their chicks during the breeding season. 

Interesting Fact: An Atlantic Puffin can hold up to a dozen small fish in its beak at once!

Nesting in burrows or natural crevices, Atlantic Puffins lay a single egg each year. Both parents take turns incubating the egg and feeding the chick once it hatches. The puffling, as the chick is known, grows rapidly and is ready to fledge about six weeks after hatching. At this stage, it makes its way to the sea alone, guided by instinct and the moonlight reflecting on the water. 

The conservation status of the Atlantic Puffin is currently listed as “Vulnerable” due to threats such as overfishing, climate change, and pollution, which impact their food supply and breeding success (Watkinson & Sutherland, 2021).
