Behaviour edit
The Atlantic puffin, like many other seabirds, spends the majority of its year at sea, far from land, and only visits coastal regions to breed. This gregarious bird typically breeds in large colonies. [25].

Mature birds return to land in the spring, usually to the colony where they hatched. It was discovered that birds that had been taken away as chicks and released somewhere else remained faithful to their original location. [30] Before going back to the cliff-top nesting sites, they gather in small groups on the sea for a few days offshore. Subcolonies within each large puffin colony are separated by physical barriers like gorse or bracken stands. The most desirable nesting sites are the closely spaced burrows on grassy slopes just above the cliff edge, where takeoff is easiest to achieve. Early arrivals grab the best spots. The reason the birds are typically monogamous is because they are loyal to their nesting sites rather than to their partners; they frequently return to the same burrows year after year. If all the prime nesting spots are taken, later entrants to the colony may be forced to the periphery, where they face increased predator risk. After a month or more, younger birds may arrive on the shore and discover that there are no more nesting sites. They do not mate until the following year, but if the colony’s surrounding ground cover is removed before these subadults arrive, there may be a higher number of pairs that are successful in building nests. [16]: 4465.
When approaching the colony, Atlantic puffins approach with caution, and they prefer not to land in an area where other puffins are not already present. They make several circuits of the colony before alighting. They spend a lot of time preening on the ground, dispersing oil from their preen gland and positioning each feather with a beak or claw. Additionally, they spend time interacting with passing birds while standing near the entrances to their burrows. An upright posture, cocked tail and fluffed chest feathers, an accentuated slow gait, head jerking, and gaping are signs of dominance. Submissive birds dart past dominant people while lowering their heads and maintaining a horizontal body posture. Normally, when a bird is ready to take off, it will briefly lower its body before sprinting down the slope to gain speed. When a bird is startled and takes off without warning, the colony may become panicked, with all of the birds jumping into the air and spinning in a large circle. In the evening, when the colony is most active, birds can be seen strolling around, resting on the turf, or standing outside their burrows. The slopes then become deserted for the night as the birds take to the skies to roost; they frequently choose to do so at fishing locations that are prepared for early-morning provisioning. [16]: 4465.
Given that puffins are enthusiastic burrow engineers and repairers, a network of tunnels may be undermining the grassy slopes. As a result, the vegetation dies, the turf dries out in the summer, and the wind whisks the dry soil away. Humans have the potential to cause burrow collapse by carelessly crossing nesting slopes. Erosion destroyed a colony on Grassholm when there was insufficient soil left for burrows to be made. [16]: 48 Because this gregarious bird only nests where other birds are already present, it is highly unlikely that new colonies will form on their own. However, the Audubon Society was successful in reintroducing puffins to Eastern Egg Rock Island in Maine, where they resumed breeding after a ninety-year hiatus. On the little islet, there were more than 120 pairs nested by 2011. [31] In 1958, there were only five pairs of puffins breeding on the Isle of May across the Atlantic; twenty years later, there were 10,000 pairs. [16]: 47.
Relationship with humans edit
The Atlantic pumpkin is found in a vast region spanning over 201,620,000 km³(625,000 sq mi) and Europe, home to more than 90% of the world’s population. It is home to 204,770,000 pairs of apples (equal to 209,550,000%E2%80%9311, 600,000 individuals). From “least concern” to “vulnerable,” the International Union for Conservation of Nature upgraded its status in 2015. This resulted from a review that showed its range in Europe was experiencing a rapid and continuous population decline. [22] While trends in other regions are unknown, 1214 million adults were estimated to make up the world’s population in 2018. [22] Increasing gull and skua predation, the introduction of rats, cats, dogs, and foxes to some islands used for nesting, contamination by toxic residues, drowning in fishing nets, decreasing food supplies, and climate change are a few possible causes of population decline. [43] From 3,500 pairs in 1939 to 10 pairs in 2000, the number of puffins on the island of Lundy declined. The primary cause of this was the rats that had overflowed the island and were consuming eggs and baby chicks. Populations were predicted to rebound after the rats were removed[44], and in 2005 a young bird was sighted, which is thought to be the first chick to have been raised on the island in thirty years. [45] According to a 2018 report by BirdLife International, the Atlantic puffin faced extinction. [46].
The number of puffins increased significantly in the North Sea during the latter part of the 20th century, especially on the islands of May and Farne, where numbers rose by roughly 10% annually. Nearly 40,000 pairs were counted during the 2013 breeding season on the Farne Islands, which is a small increase from the 2008 census and the previous year’s bad season, during which some of the burrows flooded. [47] The Icelandic colonies, where five million pairs of birds breed there, dwarf this figure; the most common bird there is the Atlantic puffin. [48] Around 1900, overfishing nearly drove Iceland’s puffin population to extinction in the Westman Islands, home to roughly half of the country’s breeding puffins. As a result, a 30-year hunting ban was imposed. Following the recovery of stock levels, a different harvesting strategy was employed, and hunting is currently continued at a sustainable level. [49] However, in 2011, a further hunting ban encompassing the entirety of Iceland was proposed, albeit the reason for the puffins’ poor reproductive performance in recent years was attributed to a decrease in food supplies instead of overharvesting. [50] Since 2000, Greenland, Iceland, Norway, and the Faroe Islands have all seen a significant decrease in population. [22] The United Kingdom has observed a similar pattern, with an apparent reversal of the increase observed between 1969 and 2000. For instance, the Fair Isle colony’s population was nearly halved by 2012 from its estimated 20,200 individuals in 1986. [22] The European population is expected to decline by an estimated 20%50%E2%80%9379% between 2000 and 202065 based on current trends. [22] In flight over the.
An initiative to save the puffins on the islands in the Firth of Forth is called SOS Puffin, and it is run by the Scottish Seabird Centre in North Berwick. The number of puffins on Craigleith Island, which was formerly home to 28,000 pairs of puffins, has drastically decreased to only a few thousand as a result of the introduction and invasion of a large plant known as the tree mallow (Lavatera arborea). This has thickened and spread throughout the island, making it difficult for puffins to find appropriate places to burrow and breed. With the help of more than 700 volunteers, the project is moving forward with plant reduction, and puffins are returning in larger numbers to breed. In late summer, the center also encourages drivers to look under their cars before leaving because young puffins may become confused by the street lights and land in the town, hiding underneath the cars. This is just one more conservation measure the center has implemented. [52].
A project called Project Puffin was started in 1973 by Stephen W. The National Audubon Society’s Kress plans to bring back Atlantic puffins to their Gulf of Maine nesting islands. Up until 1885, nesting puffins occupied Eastern Egg Rock Island in Muscongus Bay, roughly 10 km (6 mi) from Pemaquid Point. However, the birds vanished due to overhunting. Based on the typical behavior of fledgling puffins, which is to repopulate on the same island, a group of biologists and volunteers relocated 10- to 14-day-old nestlings from Great Island, Newfoundland, to Eastern Egg Rock. For roughly a month, the young were housed in artificial sod burrows and fed vitamin-enriched fish every day. Up until 1986, these yearly translocations occurred, totaling 954 young puffins. Each year before fledging, the young were individually tagged. The first adults returned to the island by 1977. On the island, puffin decoys were set up to trick the birds into believing they were a part of a well-established colony. Initially unpopular, four pairs nested on the island in 1981. In 2014, 148 nesting pairs were counted on the island. The project not only proved that it is feasible to establish a seabird colony again, but it also demonstrated the value of employing decoys, call recordings, and mirrors in the interim to aid in this process.
