Creatures have no myths or watches, so they take their signs of behavior of nature. The darkening of the sky and the decrease in temperatures caused by an eclipse They can make wildlife adopt night routines.
He Next partial solar eclipse of March 29, 2025 It could have effects on the behavior of animals due to sudden changes in light and alterations in their circadian cycles.
Animal behavior experts point out that wild species such as capibaras, migratory birds and night mammals could show unusual reactions, while domestic pets could experience temporary confusion.
Although for centuries, biologists and spectators have shared stories about how animals react to eclipses, there are very few formal studies that have proven it.
Why do animals react to eclipses?
Animals depend on natural signals such as sunlight and day/night cycles to regulate their activities. The sun serves as a compass for many species of wildlife. A solar eclipse, when the sky darkens in an abrupt way, can trigger instincts:
- Daytime animals (such as capibaras, monkeys and many birds) can interpret darkness as a signal to seek shelter or prepare to sleep.
- Night species (Bats, owls, some felines) could be activated prematurely, believing that night has come.
- Migratory birds They can stop their flight or alter their routes due to disorientation.
Effects on wild animals
One of the most famous studies on eclipses and wildlife is that of entomologist William M. Wheeler. In 1932, he directed a team that compiled almost 500 observations from the public about the behavior of the fauna during an eclipse that occurred that year.
People reported observations that included the singing of the crickets, the ulular of the owls and the return of the bees to their hives as the eclipse advanced. This study was replicated by the National Aeronautics and Space Administration (NASA) During the eclipse of April 8, 2024, And they managed to observe several changes in nature again:
- Birds that stop singing and return to their nests.
- Insects such as crickets and cicadas that begin their night sounds.
- Herbivorous mammals (such as deer and capibaras) that interrupt their diet and are grouped in search of security.
- In the case of Capibaras, highly social and diurnal animalsit has been observed that more alerts can become or withdraw in the water (their usual defense mechanism) when they perceive sudden changes in the environment.
Impact on domestic pets
While wild animals usually have more evident reactions, pets such as dogs and cats can show more subtle signs of confusion. Dogs can be restless or look for their owners to feel safe. Cats could groom more or hide temporarily, and some birds in captivity (such as parrots or canaries) can stop singing or take refuge in their hangers.
“If the eclipse is prolonged, some pets could confuse it with the arrival of the night and seek to sleep,” said Veterinary Medical Marielos Balan.
Although there is no evidence of eye damage to animals for observing the eclipse (unlike humans), it is recommended to keep them indoors to avoid stress or possible escape attempts due to disorientation.
In addition, Balan recommends:
- Keep them in a quiet environment during the phenomenon.
- Avoid getting them outside if they are nervous.
- Provide distractions (toys, snacks) to reduce anxiety.
Chronic births and diseases
“In species such as mares, cows or even dogs, it has been observed that gravitational and light changes can accelerate labor,” said Balan.
In addition, animals with chronic bone or muscle diseases could experience an increase in their discomfort, so it is suggested to ensure their medication and keep them in a quiet environment.
