Most birds head for dense vegetation, hunker down on the sheltered side of trees and structures, or drop to lower elevations where wind speeds are reduced. Rather than flying in strong winds, they tuck into spots that break the airflow and wait it out. But not all birds hide. Some species, particularly seabirds, are built to exploit wind rather than avoid it.
Dense Vegetation Is the First Choice
The most common shelter for birds in high wind is thick, layered vegetation. Dense conifers like cedars and junipers are especially valuable because their evergreen branches block wind year-round. Cardinals and other non-migratory birds rely heavily on these trees during winter storms. The key is density: a single tree in an open field offers far less protection than a thicket with multiple layers of canopy, shrubs, and ground cover.
Birds specifically seek out the leeward side of these natural windbreaks, the side facing away from the wind. This sheltered zone often gets sun exposure too, which helps birds stay warm while they wait. The USDA Forest Service notes that the most effective natural shelterbelts have tall trees on the windward side and progressively shorter shrubs on the leeward side, creating a gradient that dramatically slows airflow near the ground. Ground-dwelling birds like pheasants need shelter close to the soil surface, so low shrubs and leaf litter matter just as much as the tree canopy above.
Hedgerows, bramble patches, dense shrub rows, and even tall grass can serve the same purpose for smaller birds. If you’ve ever noticed your backyard going quiet during a windstorm and then suddenly coming alive again once it passes, those birds were likely tucked into the nearest dense cover the entire time.
How Birds Stay on Their Perch
You might wonder how a small bird perching on a branch doesn’t simply blow off. Songbirds and other perching species have a tendon-locking mechanism in their feet. When a bird lands and its weight pushes down, the tendons in its legs pull the toes closed around the branch automatically. This grip is partly passive, meaning the bird doesn’t have to actively squeeze to hold on. Research from Butler University confirmed that while muscular contractions can make the grip stronger, the basic locking action happens without conscious effort. This is the same mechanism that lets birds sleep on branches without falling, and it works just as well in a gale.
Facing Into the Wind
Birds that remain in the open during windy conditions almost always face directly into the wind. This isn’t random. Orienting head-first into the airflow keeps feathers streamlined against the body, reducing drag and preventing feathers from being ruffled open. Ruffled feathers expose skin and trap less insulating air, which means faster heat loss.
Swifts, which spend nearly their entire lives airborne, show this behavior dramatically. A study published in Proceedings of the Royal Society B found that roosting swifts orient consistently into headwinds, with their alignment becoming more precise as wind speed increases. In very strong winds, the swifts were sometimes moving backward relative to the ground, heading into the wind but unable to match its speed. Even in that situation, they maintained their heading rather than turning to fly with the wind.
When Wind Gets Too Strong to Fly
There’s a measurable point at which wind makes flight impractical or dangerous. Research published in eLife tracked seabirds called auks (guillemots and razorbills) trying to land on cliff nests in various wind conditions. In calm air, landing success was nearly 100%. Once wind reached about 9 mph (4 m/s), success started dropping. At around 18 mph (8 m/s), fewer than 20% of landing attempts succeeded. At 22 mph (10 m/s), guillemots needed up to 20 attempts to land on even the largest platforms.
Smaller songbirds face similar limits at lower thresholds. When sustained winds make controlled flight difficult, birds simply stop trying. They ground themselves in sheltered spots and stay put. Migratory birds will cancel an entire night’s travel if headwinds are too strong, which can throw off the timing of their seasonal journeys by days.
Wind Costs Birds Real Energy
Sheltering isn’t just about comfort. Wind dramatically increases how many calories a bird burns. Moving air strips heat from a bird’s body far faster than still air at the same temperature. Research in The Auk quantified this effect for songbirds: at wind speeds of about 9 mph, a bird’s energy expenditure rises meaningfully compared to sheltered conditions, because the wind effectively makes the air feel much colder than the actual temperature. The formula researchers use accounts for body temperature, air temperature, and wind speed, and it shows that even moderate wind creates a significant thermal burden.
This is why finding shelter is a survival decision, not a preference. A bird exposed to cold wind all night can burn through its fat reserves dangerously fast. The calories saved by ducking behind a row of shrubs can be the difference between making it through a winter storm and not.
Seabirds That Thrive in Wind
Not every bird treats wind as a threat. Albatrosses, shearwaters, and other pelagic seabirds have evolved to harvest energy directly from the wind using a technique called dynamic soaring. They fly in repeating cycles: climbing into the wind where airspeed is strongest, then turning and descending with the wind. Because wind speed increases with altitude above the ocean surface, this looping pattern lets them extract enough energy from the wind gradient to glide enormous distances without flapping.
Wandering albatrosses can cover hundreds of miles this way, and they actually prefer crosswinds or cross-tailwinds rather than the tailwinds that most land birds favor. Research published in Science Advances showed that in extremely windy conditions over the Southern Ocean, albatrosses can harvest more energy from the wind than they lose to drag. Their entire distribution at sea is shaped by where wind conditions support this flight style.
That said, even these wind specialists have limits. A study tracking wandering and black-browed albatrosses found that very strong winds and heavy rain reduced their ability to capture prey. Wandering albatrosses, which grab food from the ocean’s surface, had lower capture success in stormy conditions. So while they can fly in wind that would ground most birds, they still struggle to eat in the worst of it, and will sometimes avoid the most intense storms.
Where to Look After a Storm
Once winds die down, birds emerge from shelter quickly and often feed intensely to replenish lost energy. If you’re a birdwatcher, the hours immediately following a major windstorm can be unusually productive. Birds that were hunkered down in dense cover become active and visible as they forage. During migration season, strong headwinds can cause “fallouts,” where large numbers of migrants drop out of the sky into the first available habitat. Coastal areas and isolated patches of trees near open water are classic fallout spots, and they can concentrate species that normally pass through unnoticed.
