When rain begins to fall, seagulls, familiar birds often seen near coastlines and in urban areas, frequently remain visible, seemingly unfazed by the changing weather. This often sparks curiosity about how these birds navigate rainy conditions and what specific behaviors they exhibit. Their responses reveal unique adaptations and strategies for thriving in diverse environments.
Immediate Responses to Rain
Seagulls often do not seek obvious shelter when it rains. They endure wet and windy conditions, often seen standing in open areas such as fields, beaches, and parking lots. They might continue their regular activities or simply stand still, sometimes facing into the wind. While they can fly in rain, during heavier downpours, they may remain motionless to allow water to run off their feathers or seek some form of minimal shelter. This shelter can include large rooftops in urban environments or calm waters where they can rest.
Before significant storms, seagulls move inland, sensing changes in air pressure. This movement can indicate approaching severe weather. Once inland, they might fly low over the surface or stay grounded, adjusting their behavior to accommodate atmospheric changes. Another observed behavior, particularly on grassy areas, is the “rain dance,” where seagulls stamp their feet to mimic the vibrations of rain. This action encourages earthworms to surface, providing the gulls with an accessible food source.
Why Rain Doesn’t Always Deter Them
Seagulls possess several biological adaptations that allow them to withstand rainfall without extensive shelter. Their water-resistant plumage is maintained through preening. They apply waxes and oils from their uropygial (preen or oil) gland, located at the base of their tail feathers. This oily secretion, distributed across their feathers, helps to repel water, preventing it from soaking through to their skin.
Beyond the oil, the intricate physical structure of feathers contributes to waterproofing. This natural design, combined with the oil, allows water to bead up and roll off, keeping the bird’s body insulated and dry. Seagulls regulate their body temperature. They can fluff up their feathers to trap a layer of warm air close to their bodies, enhancing insulation against the cold and wet. These combined adaptations mean that rain is a normal and manageable part of their environment, not an immediate threat.
Factors Influencing Their Behavior in Rain
While seagulls are resilient to rain, external factors influence their behavior during different types of rainfall. The intensity of the rain plays a role; light drizzle prompts little change, as water sheds easily. However, during heavy downpours, they are more likely to seek out sheltered spots, even if minimal, or simply remain still to conserve energy.
Wind conditions also affect their actions. Strong winds can influence their foraging patterns and flight paths, sometimes leading to shorter foraging trips. If both heavy rain and strong winds are present, gulls may reduce their foraging distances and stay closer to their roosting areas, such as urban colonies or sheltered coastal spots. Location also matters; urban areas provide structures like buildings and rooftops for temporary refuge, unlike open beaches where shelter is scarce. This adaptability allows them to thrive in diverse environments, from open seas to cities.
