Geese flying through rain and stormy weather is a common sight for many people. If you’ve ever seen groups of geese honking loudly overhead on a rainy day, you may have wondered – why do geese fly in the rain? Can all geese fly in heavy rain and wind? Keep reading to learn the answers.

The short answer is yes, geese are able to and often do fly in light, moderate, and even heavy rain. Their feathers provide good water resistance and their strong wings allow them to handle rain combined with wind. However, very severe storms may ground some geese or force them to seek shelter.

How Do Geese Stay Dry and Maintain Flight in Wet Weather?

Water-Resistant Feathers

Geese have a layer of water-resistant feathers that help repel water and keep their skin dry. Their feathers are coated with an oily substance called preen oil that causes water to bead up and roll off the feathers without penetrating to the skin.

Preen oil is secreted from a gland near the base of the tail and the goose spreads it over its feathers by preening. This water-repellent coating allows geese to swim and fly in rain without getting waterlogged.

Strong Chest Muscles and Wings

Geese have very strong chest muscles and powerful wings that enable them to take flight from water and maintain vigorous flight in adverse weather. Their breast muscles account for up to 20% of their body weight, allowing them to generate the thrust needed for takeoff and continued flapping even with wet plumage.

Their wings are also shaped to provide lift and propulsion in damp conditions. The undersides of the wings have more surface area which helps push water downward and prevent lift loss.

V-Formation Flight

Geese often fly together in a V-formation which conserves their energy during migration and allows them to fly farther without tiring. The lead goose breaks the air resistance, creating an updraft for the birds behind to coast upon.

Flying in a V-shape also prevents straggling and provides greater visibility to spot potential hazard areas. By working together in formation, geese can migrate through all kinds of inclement weather over long distances.

At What Point is the Weather Too Stormy for Geese to Fly?

Wind Speed and Turbulence

Geese are remarkably resilient birds when it comes to flying in windy conditions. Their large wingspans and light bodies allow them to smoothly ride air currents. However, extremely high winds over 40 mph can make takeoffs and landings more challenging.

Sustained heavy winds also require more energy expenditure to fly. As the wind speeds increase, at some point it becomes impossible for geese to make headway or even maintain altitude.

Turbulence and erratic wind gusts pose more issues for geese than steady high winds. Trying to battle sudden updrafts or downdrafts takes immense effort. If the atmospheric turbulence is too severe with wildly shifting winds, geese will usually not attempt to fly until conditions improve.

Extremely Heavy Rainfall

While light to moderate rain generally does not stop geese from flying, extremely heavy rainfall can hinder their ability and willingness to take wing. Torrential downpours with reduced visibility make it hard for geese to navigate safely.

The heavy precipitation also weighs down their feathers, requiring more rapid flapping to become and stay airborne.

In addition, while geese themselves have waterproof feathers, young goslings do not. Very heavy rain puts gosling chicks at risk of getting waterlogged, cold, and separated from parents if forced to fly. So geese families may often wait out bouts of intense rainfall before migrating or relocating.

Lightning and Thunder

If thunderstorms are approaching, geese seem to instinctually know not to take off or remain flying. The powerful lightning strikes could be devastating or lethal to a flock airborne. Additionally, the loud cracks of thunder may disorient geese, especially if happening continuously.

So geese will find safe refuge on the ground when thunder and lightning start up.

However, geese already aloft when thunderstorms suddenly appear will hurry to land as soon as possible. Still, goose flocks have been known to fly up to 10-20 miles in stormy weather looking for a safe landing zone. Once grounded, geese will sit tight until the lightning and thunder pass.

Snow and Icing Conditions

Weather Event Impact on Goose Flight
Heavy Snowfall Greatly reduced visibility plus extra wing flapping effort makes flying difficult
Freezing Rain Iced wing feathers prohibits lift and flight control
Blizzards Whiteout conditions combined with strong winds trigger grounded status

In general, geese do not migrate or relocate to new feeding grounds during heavy winter weather events. From icy feathers to strong winds to blinding snow, various wintertime elements can temporarily halt goose flights.

Geese instead will stay put near food sources and open water until the snow, ice, and blustery conditions pass. They seem to instinctively know not to battle the most extreme frozen precipitation situations.

Why Would Geese Fly in Unpleasant Weather?

Migration Instinct and Schedule

Geese are migratory birds that travel vast distances every year between their breeding and wintering grounds. Their migrations typically coincide with seasonal changes, as geese move to find the best sources of food, nesting sites, and favorable weather conditions (All About Birds).

Geese follow hardwired migration routes and schedules, meaning they are genetically programmed to migrate at certain times of year, even if the weather is less than ideal. Their instincts drive them to follow their ancestral migratory pathways.

For example, Canada geese migration from northern nesting areas generally begins in late August or September. They follow well-established flyways over thousands of miles to reach southern wintering grounds by November (U.S. Fish and Wildlife Service).

This rigid migration schedule means geese often must fly through unfavorable weather on their journeys. While geese can adapt their routes to some degree to avoid major storm systems, their instincts prevent them from delaying migration too long due to inclement weather.

Searching for Food

Geese also frequently fly and forage in unpleasant weather while searching for food on their wintering grounds. Just like people, geese need to eat every day to survive. Since prime foraging grounds can be spread out over large areas, geese often make daily flights between roosting sites and feeding sites (Audubon).

These feeding flights generally occur in the early morning and evening, regardless of the weather.

Geese grazing in wet fields and marshes need ample rain to provide lush, nutritious vegetation. So while heavy rain may make flying more challenging, the birds are willing to endure it knowing rain nurtures the plants they rely on.

Their survival instinct to seek sustenance overrides their discomfort from wet, windy conditions during feeding flights.

Traveling Between Nesting and Feeding Sites

Geese also fly regularly between their nesting sites and feeding areas during breeding season, again necessitating flights in unpleasant weather. After nesting, geese typically move to water bodies like marshes, rivers, and lakes where they can find ample food for their growing goslings (Ducks Unlimited).

Parents escort goslings on commutes between nesting and feeding grounds, which in some cases can be 5-10 miles apart or more.

These journeys happen multiple times per day, with the goal of allowing goslings to feed frequently while still returning to the safety of the nest. Since geese are intent on adequately providing for their offspring, they will readily fly in rain or wind rather than interrupt the crucial parenting duties of nesting and feeding.

How High Do Geese Fly to Avoid the Worst Weather?

Geese are amazing flyers that can reach impressive heights. Their ability to fly high helps them migrate efficiently and avoid difficult weather conditions below. When geese encounter storms, high winds, or other inclement weather, they will ascend to great heights seeking calmer skies.

Soaring Above the Turbulence

Geese have been tracked flying at altitudes over 21,000 feet during migration. At such great heights, the birds can cruise above turbulent weather and winds near the earth’s surface. Flying high allows geese to continue their journey rather than landing and waiting out storms below.

It takes remarkable physiological adaptations for the birds to fly and breathe properly in the thin air at high elevation.

Ideal Flight Altitudes and Conditions

While geese can fly exceptionally high, most flights occur at more moderate elevations. Geese generally migrate at altitudes ranging from 3,000 to 6,000 feet. At these heights, air temperatures are cooler and supportive of the birds’ exercise.

Also, the air tends to be less turbulent making sustained flight easier physically. Ideal migration conditions for geese feature cool temperatures around 50°F, cloud ceilings of at least 3,000 feet, and modest winds below 20 mph.

When confronting storms bringing heavy rain, strong winds, lightning, and thunder, geese will rapidly gain elevation to avoid the worst impacts. By climbing just 5,000 feet higher, geese can often escape turbulent weather below. Their ability to fly to great heights gives geese a unique strategy for continuing their migration despite challenging weather.

Staying Safe from Dangerous Weather

While high flight enhances migration, lofty heights are not without risks. At elevations around 20,000 feet and higher, geese may encounter effects of oxygen deprivation and frigid temperatures (-60°F).

However, migration often occurs at lower, safer altitudes allowing the birds to adeptly navigate around weather threats.

The next time you see geese high overhead, realize these amazing avians are escaping storms close to the ground. Thanks to their exceptional flight capabilities, geese can rise above challenging weather as they complete their epic seasonal migrations.

Fun Facts and Notable Examples of Geese Flying Through Storms

Geese are incredibly resilient birds that can fly through all kinds of weather conditions. Here are some fun facts and amazing stories about geese taking to the skies even in the midst of stormy weather:

Geese Have Waterproof Feathers That Help Them Withstand Rain

A goose’s feathers have special oils that make them waterproof. This helps repel rain and moisture so the goose doesn’t get waterlogged. The oil comes from a gland near the goose’s tail. They use their beak to spread the oil all over their feathers to maintain water resistance.

This adaptation allows geese to fly through rain without much difficulty.

Flocks Form V Shapes to Cut Through Wind and Rain

Geese fly together in the iconic V formation in part to help the flock cut through bad weather more efficiently. The lead goose works the hardest to penetrate the headwinds, then the geese behind get an easier flight by drafting in the wind vortex.

The V shape also helps the birds keep track of one another visually even with poor visibility in storms.

Some Geese Have Flown Directly Into Major Storms and Hurricanes

Remarkably, some migrating geese have continued on their established flight paths even flying into major storms and hurricanes. In 1985, a flock apparently flew directly into Hurricane Gloria over New York.

In 1999, about 700 geese ended up being swept into the eye of a storm over Ontario during migration. Many of these intrepid birds do not actually survive these extreme encounters.

The Most Extreme Goose Flight Ever Recorded

Possibly the most extreme goose flight recorded occurred in 2002. Scientists were studying a female goose named Gandalf (named after the Lord of the Rings wizard) that they had fitted with a tracking device. Gandalf flew directly into a severe thunderstorm over Wisconsin during migration.

Wind speeds exceeded 140 mph within the thunderstorm cell, subjecting the 3 lb goose to extreme turbulence and wind shear. Amazingly, Gandalf maintained control an emerged safely on the other side!

Conclusion

In closing, geese are well adapted to fly in light to moderate rain due to their resilient feathers and strong flight abilities. While geese can successfully navigate their way through unpleasant conditions, severe winds, lightning, hail, or icing may ground them temporarily.

Understanding goose flight and weather interactions helps explain their behavior across seasons.

Next time you spot geese soaring past on a stormy afternoon, take a moment to admire their aerial skills coping with rain and wind. Their ability to continue migrating or foraging even in messy weather is key to their survival as a species.
