While the winter months usually drive us closer to the indoors, spending time with our loved ones, for puffins it is quite the opposite. Puffins are true seabirds, and what this means is they will spend majority of their lives out over the ocean. While they will only come to land to breed, you may be fooled into thinking that this social behaviour seen on land is their year-round character. Realistically, puffins are mostly solitary and spend their winters following their food out in open waters. While during the breeding season puffins hunt in groups of around 7 individuals, during winter puffins will be foraging either alone, or with one other individual. Puffins follow a unique migration route and tend to repeat this winter route yearly, leading to a more solitary lifestyle.
Wintertime is also when puffins will conduct their yearly moult, losing their flight feathers. During this moulting period, they are unable to fly, and this can provide a disadvantage if their food supply is low and storms occur. Recent research suggests that the yearly moult start and finish times vary between individuals, as well as the duration. On average this moult is thought to take between 1-2months, which is a significant time for these seabirds to go without flight and limited foraging ability.
