Most birds evacuate well before a hurricane arrives, fleeing hundreds of miles inland or to calmer skies. The ones that stay hunker down in dense vegetation, tree cavities, or other sheltered spots close to the ground. Seabirds at sea face a different challenge entirely, and some use a surprisingly counterintuitive strategy: flying directly into the eye of the storm.
What happens to any given bird depends on its size, where it lives, and whether it’s on land or over open water when the storm hits.
How Birds Know a Storm Is Coming
Birds have at least two biological systems that give them advance warning of approaching storms, often days before human forecasters issue local alerts. The first is a pressure-sensing organ in the middle ear called the paratympanic organ. It contains a fluid-filled chamber lined with tiny hair cells. When barometric pressure drops, the eardrum shifts inward, deforming that chamber and bending the hair cells. This lets birds detect pressure changes as small as the equivalent of rising or descending 10 to 20 meters in altitude.
The second system involves infrasound, the ultra-low-frequency acoustic waves (below 20 hertz) that severe storms generate as they churn through the atmosphere. Birds can hear these frequencies; humans cannot. In 2014, a UC Berkeley research team tracked golden-winged warblers in the mountains of eastern Tennessee that abandoned their breeding territory one to two days before a line of supercell storms arrived. The storms were still 250 to 560 miles away at the time, and local weather conditions showed no obvious signs of danger. The birds simply left, flew south, then returned after the storms passed. Infrasound traveling ahead of the storm system was the most likely explanation.
Where Land Birds Take Shelter
Small songbirds that don’t evacuate early typically seek the densest, lowest cover they can find. Thick shrubs, tangled brush piles, and the interior branches of evergreen trees offer protection from wind and flying debris. Some birds wedge themselves into tree cavities, rock crevices, or the leeward side of buildings. The goal is to get out of the wind column and reduce exposure to rain.
Cavity-nesting species like woodpeckers have a built-in advantage. Research following Hurricane Andrew in 1992 found that the abundance of cavity-nesting birds in bottomland hardwood forests was not significantly affected by the storm’s damage. Birds that nest in enclosed spaces already have access to sturdy, wind-resistant shelter. Open-cup nesters, by contrast, face worse odds. The northern parula, a small warbler that builds exposed nests draped in hanging moss, showed clear population declines in areas with heavy hurricane damage.
Larger land birds, including raptors and wading birds, generally relocate ahead of the storm if they can. Many fly perpendicular to the storm’s path, moving inland or to the north or south to escape the wind field. Birds that are mid-migration when a hurricane crosses their route will often stall and wait, sometimes landing in unusual locations until conditions improve.
Seabirds Fly Into the Eye
Pelagic seabirds, the ones that spend most of their lives over open ocean, face a unique problem. There’s nowhere to land, and flying against hurricane-force winds is impossible. So some species do the opposite of what you’d expect.
A study published in the Proceedings of the National Academy of Sciences tracked streaked shearwaters during multiple typhoons in the western Pacific. When winds intensified and the birds were caught between the storm and land, they flew toward the eye of the storm rather than away from it. Some came within 30 kilometers of the eye, operating in or near the eyewall where wind speeds reached up to 47 miles per hour. They then tracked the eye’s movement for up to eight hours.
This sounds reckless, but the strategy makes sense. The eye itself is relatively calm, with light winds and clear skies. And by staying near the eye as it moved, the birds avoided something potentially more dangerous: the powerful onshore winds that follow in a storm’s wake. Being blown onto land or into coastal waters would be far more lethal for a bird adapted to open ocean life. Flying into the storm was the safer option.
Storm Displacement and Vagrants
Not every bird manages to dodge a hurricane. Some get caught in the circulation and are carried far outside their normal range, sometimes hundreds or even thousands of miles. Birders call these storm-displaced individuals “vagrants,” and major hurricanes reliably produce them.
The most dramatic recent example came from Hurricane Idalia in 2023. As the storm crossed the waters between the Yucatan Peninsula and Cuba, it swept up a large number of American flamingos that were likely making their regular seasonal movement between those areas. The flamingos were carried across the Gulf of Mexico and scattered across the eastern United States, turning up in 18 states, many of which had never recorded a wild flamingo before. Sightings from Wisconsin to Ohio to Virginia made national news.
This wasn’t an isolated event. Hurricane Agnes in 1972 deposited a flamingo on Assateague Island in Maryland. Frigatebirds, tropicbirds, and petrels from the Caribbean regularly appear along the U.S. Atlantic coast after hurricanes, sometimes showing up at inland lakes and reservoirs hundreds of miles from the ocean. These birds are typically exhausted and disoriented. Some recover and eventually find their way back. Others don’t survive.
What Happens to Nests and Young
Hurricane season overlaps with the tail end of breeding season for many North American species, which means active nests are sometimes directly in the path of a storm. Open nests in trees are especially vulnerable. High winds strip branches and topple trees, destroying eggs and killing nestlings that can’t fly. Ground-nesting shorebirds along the coast face storm surge that can flood entire nesting colonies in hours.
Adult birds almost always prioritize their own survival over their nest. A bird that abandons eggs can breed again next year. One that dies defending a nest cannot. This means that even when adult mortality from a single storm is relatively low, reproductive losses for that season can be severe. Colonies of terns, plovers, and skimmers along the Gulf Coast have been wiped out in a single storm event, requiring years of recovery.
The habitat itself also changes. Hurricanes strip canopy cover, flatten understory vegetation, and alter the structure of forests in ways that favor some species over others. After Hurricane Andrew, species that depended on dense canopy and hanging moss declined in damaged areas, while birds that thrive in open or disturbed habitats moved in. The storm doesn’t just displace birds temporarily. It reshapes which species can live in an area for years afterward.
