Behavior of animals during a solar eclipse One of nature’s most peculiar and spectacular phenomena is the solar eclipse. When the Moon passes between the Earth and the Sun, it creates a shadow that temporarily alters the light and temperature in some areas of the planet. Solar eclipses offer a unique chance to study wildlife in settings that resemble abrupt nightfall, but scientists also pay close attention to what these phenomena indicate about the Sun and Moon.
An annular solar eclipse, sometimes known as a “Ring of Fire” eclipse, is scheduled for February 17, 2026, however it will not be visible from India. Nonetheless, knowing how animals often respond to eclipses enables us to see how environmental cues such as lighting, temperature, and seasonal cycles influence the behavior of both domestic and wild animals.
The US Fish & Wildlife Service states that animals’ ability to control their activity patterns is mostly dependent on natural light. Similar behavioral changes to those observed at dawn or dusk can be triggered by an abrupt reduction in daylight. During previous solar eclipses, several animals have shown changes in their feeding habits, vocalizations, and activity. To find out more about how animals respond to abrupt changes in their surroundings and how their internal biological clocks adapt to unforeseen changes, researchers and wildlife observers have studied these behaviors.
The type of eclipse (total or annular), the species, and the habitat all influence how various species respond to a solar eclipse. When the Sun is totally obscured during a total eclipse, people frequently comment on how spectacular it is. However, light-sensitive animals can be impacted by even an annular eclipse, in which the Sun is only half obscured. Based only on scientific records and firsthand observations from previous eclipses, the following sections describe the reactions of various animal species and the reasons behind them.
How temperature and light affect animal behavior during a solar eclipse
In order to maintain their circadian rhythms—the internal “biological clock” that tells them when to eat, relax, or seek cover—animals rely on external cues like temperature and sunlight. A solar eclipse causes the sky to darken quickly and may cause a modest dip in temperature. People may behave differently in the morning or at night as a result of these abrupt adjustments.
Species from insects to huge mammals sometimes change their activity when light levels suddenly drop, even for a brief period of time, according to the US Fish & Wildlife Service.
The actions of animals during a solar eclipse
Birds: Signs of dawn and dusk
Among the creatures that are most commonly seen to alter their behavior during eclipses are birds. Numerous birds alter their habits when the light level decreases, according to both scientific research and anecdotal data.
Scientists believe that animals do not react to a solar eclipse because they understand what is happening in the sky. Instead, their responses are triggered by sudden changes in environmental light and temperature. For many species, light acts as a biological signal that controls daily routines such as feeding, movement, and rest. When daylight suddenly fades during an eclipse, animals may mistake it for dusk.
Insects: Confusion and Shifts in Activity
Insects are especially sensitive to changes in light. Their daily activities—such as searching for food, mating, and navigating—depend heavily on sunlight.
Research published in Scientific Reports found that bees significantly reduced their flight activity during a solar eclipse. The sudden dimming likely disrupted their ability to locate flowers and orient themselves properly.
Meanwhile, some nocturnal insects respond in the opposite way. Crickets, fireflies, and other dusk-active species may suddenly become more active, behaving as though evening has arrived. This rapid shift highlights how strongly insects rely on light cues to regulate their behaviour.
Mammals and Other Vertebrates: Unusual Reactions
Larger animals, including mammals and reptiles, also display noticeable behavioural changes during eclipses. In one study conducted at a zoo during a previous solar eclipse, researchers observed 17 different species. Nearly 75% of them showed altered behaviour.
Many animals began engaging in routines typically associated with nighttime, such as resting, retreating to shelters, or reducing movement. Some species displayed signs of confusion or anxiety, including pacing, vocalizing more frequently, or moving in unusual patterns compared to their normal daytime activity.
These reactions suggest that the sudden darkness and temperature drop can temporarily disrupt animals’ internal clocks, leading them to behave as if day has abruptly turned into night.
Observed Animal Reactions During Eclipses
Documented observations from past solar eclipses show a wide range of responses across species.
Giraffes and primates have been seen adjusting their movement patterns as light levels gradually dropped.
Some elephants and lorikeets began behaving as if dusk had arrived, preparing for evening routines earlier than usual.
However, not every species reacts dramatically. Depending on their natural activity cycles and sensitivity to light, some mammals, reptiles, and birds show little to no noticeable change. Species that are less dependent on visual daylight cues may continue their normal behaviour without disruption.
Marine and Aquatic Life: A Less Studied Response
Marine ecosystems also respond to shifts in sunlight, although research in this area is more limited compared to terrestrial wildlife.
Reports suggest that whales, fish, and other marine species may alter their behaviour during eclipse conditions. A sudden drop in surface light and changes in water luminescence can influence feeding, swimming depth, and movement patterns.
However, these responses are highly species-specific and remain less thoroughly documented than land-based animal reactions.
Why Not All Animals React the Same Way
Scientific research shows that animals do not respond uniformly to solar eclipses. Behavioural changes depend on several key factors:
Species-specific sensitivity to light
Whether the eclipse is total or partial
The animal’s natural sleep–wake (circadian) cycle
Immediate environmental cues and habitat conditions
A study published in Science in 2025 found that while some bird species became unusually quiet or altered their flight behaviour during an eclipse, others showed almost no reaction. This variation highlights how differently species perceive and interpret sudden environmental changes.
What This Means for the Solar Eclipse on February 17, 2026
Today grahan timing The annular solar eclipse on February 17, 2026, will not create complete darkness like a total eclipse. However, it will still cause noticeable dimming in regions where it is visible.
Even this moderate reduction in sunlight can be enough to trigger behavioural adjustments in animals that rely heavily on daylight cues to regulate feeding, communication, and movement.
Why Eclipse Research Matters
Understanding wildlife reactions to solar eclipses provides valuable insights into:
Animal perception
Circadian biology
Behavioural ecology
Studies from previous eclipses suggest that many species temporarily shift their behaviour during these rare astronomical events. However, once normal sunlight returns, most animals quickly resume their regular daily patterns.
Solar eclipses may last only minutes—but for wildlife, even a brief change in light can momentarily reshape the rhythm of the natural world.
Q1: What happens to animals during a solar eclipse?
During a solar eclipse, animals often change their behaviour because of the sudden drop in light and slight decrease in temperature. Many species respond as if dusk has arrived, adjusting feeding, movement, or resting patterns temporarily.
Q2: Why do animals react to a solar eclipse?
Animals do not understand the astronomical event itself. Their reactions are triggered by environmental changes—mainly reduced sunlight and cooler temperatures.
According to the U.S. Fish & Wildlife Service, many animals rely on natural light to regulate daily activity cycles. When daylight suddenly fades, it can confuse their internal biological clocks (circadian rhythms).
Q3: How does light affect animal behaviour during an eclipse?
Light acts as a biological signal that tells animals when to:
Feed
Rest
Hunt
Seek shelter
Vocalize
When light levels drop quickly, animals may interpret it as sunset, leading to behaviours typical of evening or nighttime.
Q4: How do birds react during a solar eclipse?
Birds are among the most noticeably affected species.
Many birds reduce activity.
Some stop singing and return to nests.
Others show dusk-like behaviour.
However, responses vary by species. Some birds become quiet, while others show minimal change.
Q5: What happens to insects during a solar eclipse?
Insects are highly sensitive to light changes.
Research published in Scientific Reports found that bees significantly reduced flight activity during an eclipse.
Nocturnal insects such as crickets and fireflies may suddenly become active, behaving as though evening has arrived.
This shift occurs because insects depend heavily on sunlight for navigation and feeding.
Q6: How do mammals and reptiles respond?
Larger animals also display noticeable changes.
A zoo-based study observing 17 species during a past eclipse found that nearly 75% showed altered behaviour. Common reactions included:
Reduced movement
Resting earlier than usual
Retreating to shelters
Signs of confusion or anxiety
Examples include giraffes and primates adjusting movements as light dimmed, while elephants and lorikeets acted as if dusk had begun.
Q7: Do marine animals react to solar eclipses?
Marine life responses are less extensively studied. However, reports suggest that whales and fish may change swimming patterns or feeding behaviour due to reduced surface light and changes in water brightness.
These reactions are species-specific and less documented than land-based animal behaviour.
Q8: Why don’t all animals react the same way?
Animal responses depend on several factors:
Species-specific sensitivity to light
Whether the eclipse is total or annular
Natural sleep–wake cycles
Habitat and immediate environmental cues
A 2025 study published in Science showed that some bird species reacted strongly during an eclipse, while others showed almost no change.
Q9: What is special about the solar eclipse on February 17, 2026?
An annular solar eclipse—often called a “Ring of Fire” eclipse—will occur on February 17, 2026.
Although it will not be visible from India, it will still cause noticeable dimming in regions where it is visible. Unlike a total eclipse, it will not create complete darkness, but even partial dimming can influence light-sensitive species.
Q10: Why is studying animal behaviour during eclipses important?
Solar eclipses provide scientists with a rare opportunity to observe how wildlife responds to sudden environmental changes.
Studying these reactions helps researchers better understand:
Animal perception
Circadian biology
Behavioural ecology
Although the eclipse may last only minutes, it offers valuable insight into how animals interpret and adapt to abrupt shifts in their surroundings.
