Birds of a feather flock together At this time of year, our skies can be compared to Heathrow Airport on a busy day as flocks of birds arrive from and depart to warmer climes. Safety in numbers A larger group of birds boasts a much better chance of spotting a predator, or other potential threat, than a single bird has.
Knots in flight Knots fly in close formation to avoid predators Read video transcript Knots fly in close formation to avoid predators. Faster food foraging Birds do not engage in any behaviour that does not bring them a benefit for survival in some way. Clubbing together Some birds also choose to nest close together to take advantage of 'safety in numbers'. In a colony, each nest is carefully tended to by parent birds caring for their young.
Flying V When birds fly in flocks, they often arrange themselves in specific shapes or formations. Keeping warm In winter, flocks can share the benefit of communal warmth to survive cold temperatures, such as the common scoter. And large flocks may congregate in a single tree to share their body heat, too.
In short, there's much more to a flock of birds than first meets the eye! Starling murmuration A flock of starlings participate in a spectacular aerial display Read video transcript A flock of starlings participate in a spectacular aerial display.

So, there are two main reasons why birds travel together in groups — for safety and to make the long-distance flying easier.

While migrating bird flocks can be spotted during the daytime, most birds migrate at night when the air is cooler and calmer, and there are fewer predators , flying in tandem even when they are feet meters or more apart, according to a University of Illinois study published in the July issue of the journal Integrative and Comparative Biology.
Some birds, including swans, geese, cranes, pelicans and flamingos , form tight, V-shaped patterns, while others fly together in loose flocks. V-shaped formations help birds conserve energy, since each bird flies slightly ahead of the other, there is less wind resistance. To keep things fair, birds take turns being in the front, with each bird moving to the back when they get tired, according to the National Park Service. Age, sex and body size also play a role in who leads the V-formation.
While no attacker is willing to take on the entire flock, the large flock is may be obvious enough to attract several predators that are willing to lurk in the vicinity waiting for weak or unsuspecting members to lag behind the flock. Yet another problem is disease. Many avian diseases are spread through direct contact or fecal matter; both of which occurs in abundance when large numbers of bird congregate for an extended period of time.
Regardless of why birds congregate in winter, the fact that they do gather, coupled with a lack of foliage that increases viewing opportunities, is another reason why this is a great time to get outside and enjoy nature.
