Strange Animal Behavior to Watch for During April’s Solar Eclipse

On April 8th, while most people in the United States will be staring into the sky (preferably wearing appropriate safety glasses), animals will have no idea what’s going on.

That’s natural, right? For animals, the sun constitutes their entire life. Without energy drinks and late-night TV to disrupt their sleep schedules, the sun is an all-in-one alarm clock, sleeping pill, and calendar for animals.

In 2017, a team of researchers studied how different animals responded to a total solar eclipse in the United States.

“Basically, everything we’ve ever heard about animal behavior during a solar eclipse can reasonably be considered anecdotal from a scientific perspective.” Professor Adam Hartstone Rose says the person who led the research. BBC Science Focus.

Hartstone-Rose and his team observed the behavior of 17 species at Riverbanks Zoo in Columbia, South Carolina. This is the first time such a study has been conducted. What did they find? Now, how animals behave during a total solar eclipse varies dramatically, from not at all bothersome to downright weird…

Strange ways animals may react to solar eclipses

Heartstone-Rose said animals responded to celestial events in one of four ways. These include not responding at all, starting nighttime routines, showing anxiety, and exhibiting new behaviors.

“Most animals fall into a category that we call related to circadian rhythms. So basically, animals treat solar eclipses as if they were evening, then night, then morning; “I get into a routine,” he says.

Similar nighttime routines have been widely reported for other eclipses. As the moon passes in front of the sun, expect birds to quiet down and crickets and cicadas to become more active.

The next largest behavioral category was, somewhat sadly, anxiety-related behaviors. For example, evidence gathered by Hartstone-Rose and her research team suggests that if you’re near a giraffe during a solar eclipse, you should stay well away from them.

“During the peak of the eclipse, the giraffes started running around like crazy and in potentially dangerous ways,” Hartstone-Rose explains.

“Giraffes in the wild are very gentle animals. They’re a little bit wild and sensitive. They don’t do crazy things unless they have to, so when I saw giraffes running around…, only when startled by a predator, vehicle, etc.”

Thankfully, any disturbing behavior didn’t last long. “The good news is that all of the animal’s behavior returns to normal very quickly, literally within minutes.”

But what about these so-called “novel” behaviors? This is where things get weird.

The siamang is a type of gibbon that lives in the forests of Indonesia, Malaysia, and Thailand. Although they look cute, they are known to be very noisy and have large throat pouches.use their heads to help sing.

The research team recorded the calls of the siamang during and for several days before and after the eclipse, and found that it emitted a unique call during the totality. It was something they had never heard before.

“We were able to statistically show that vocalizations during a solar eclipse are much different than at any other time we’ve been able to record vocalizations,” Hartstone-Rose says. “That was pretty remarkable.”

The prize for the strangest solar eclipse behavior is… giant tortoise?

If anxious runs and strange songs weren’t enough, Riverbanks Zoo’s Galapagos tortoises took their reaction to the solar eclipse to a different level.

“Galapagos tortoises are not charismatic animals,” Hartstone-Rose says. “They’re like weird looking rocks that can live to be well over 100 years old.”

According to stereotypes, they are not particularly fast moving and the males Weight is over 227 kg making it the largest turtle species on Earth.

When the sun eclipsed the moon in 2017, Galapagos tortoises started doing something unexpected. They literally started breeding right before our eyes. “

Therefore, a solar eclipse may lift your turtle’s mood. Did anyone know?

How can I participate this time?

After 2017’s surprising discoveries, researchers hope to do even more this year.

Hartstone-Rose and a team of researchers plan to observe animal behavior at the Fort Worth Zoo in Texas. They will observe and compare some of the same species and new species from 2017.

But you don’t have to be a trained researcher to help scientists understand animal behavior during this once-in-a-lifetime event.

“The really exciting research we’re doing is solar eclipse safari project” says Heartstone Rose.

If you want to participate, just choose the animal you want to observe, whether it’s a dog, cat, domestic animal, or natural animal.

You don’t have to go down the path of perfection either. There will be at least a partial solar eclipse across the United States on April 8, and researchers want to know whether the severity of the eclipse affects behavior.

Before you worry that you’ll miss the eclipse itself because you’re too busy checking to see if your dog is scratching its ears, don’t worry. Data collection only takes a few seconds every few minutes, so you still have time to understand everything.

Why study animals during a solar eclipse?

While understanding how different animals behave during a solar eclipse may seem interesting to some, it is ultimately a pointless endeavor. Fair point. Although there is some method to madness.

First, Hartstone-Rose points out that it’s important to understand which animals exhibit anxiety.

“If solar eclipses are upsetting, or if the human response to solar eclipses is upsetting, that’s important information for us to know. For example, giraffes really If it runs around, it may be ethical to move the giraffe indoors during the next solar eclipse.

“At the end of the day, we don’t want them to hurt themselves.”

Even more poignantly, he thinks this could answer some of the big questions about our relationship with animals.

“One of the big questions, and anyone who has a pet dog or cat knows this, is what’s going on inside this animal’s head. Do you know? ? What is my dog thinking at any given moment? People have such questions not only about dogs, but about all their favorite animals.”

Perhaps by understanding how animals respond to one of the most unique and fascinating experiences on earth, we can move one step closer to solving the mystery.

Ambitious plan to observe the sun during April’s solar eclipse

NASA’s WB-57 research jet will be used to study solar eclipses

Amir Caspi

Solar scientists across North America will study April’s total solar eclipse to observe the sun’s strangest part: the corona.

Although it is briefly visible as a bright halo that appears only when it is total, it is a million times dimmer in visible light than the rest of the Sun. The corona is also a million degrees warmer than the sun’s surface, or photosphere, which only reaches about 6000 degrees Celsius, and extends millions of kilometers into the solar system.

The corona is where the sun’s magnetic field acts on charged particles to form complex shapes called streamers, loops, plumes, etc. Understanding the corona helps us predict the solar wind, the stream of charged particles that is blown into space from the Sun. This is the cause of the aurora borealis, but it’s also a potential threat to astronauts, satellites, and the power grid.

Expectations for the total solar eclipse on April 8th are extremely high. That’s because the total solar eclipse, in which the sun is completely covered, will last up to 4 minutes and 27 seconds, the longest such period on land in more than a decade. We would like to introduce some of the experiments that will be carried out in the future.

solar wind sherpa

Shadia HabalThe solar researcher at the University of Hawaii Institute for Astronomy has been tracking solar eclipses for almost 30 years, using special filters and cameras to measure the temperature of particles from the deepest part of the corona.

Habal’s group, now known as the Solar Wind Sherpas, has traveled to far-flung places, including the Marshall Islands, Kenya, Mongolia, Norway’s Svalbard, Antarctica, and Libya. Habal and her team use filters to image the corona during each solar eclipse, some of which last only a few seconds. By studying the different wavelengths of light emitted by charged iron particles in the corona, temperature can be revealed.

Most often, solar physicists who study the corona rely on space observatory coronagraphs, which use telescope disks to block the sun. But these devices obscure the deepest parts of the corona, towers of plasma called prominences and sources of eruptions called coronal mass ejections.

“Observations during totality are very important,” Habal says. There’s no other way to continuously observe a portion of the Sun’s atmosphere extending from the surface to at least 5 solar radii. “This is fundamental to understanding how the solar atmosphere originates from the Sun and then spreads out into interplanetary space,” she says. Only then will accurate computer models be devised to simulate the corona and help predict space weather.

In the past few years, Habal’s group has made a surprising discovery. The Sun is currently heading towards her solar maximum in 2025, the most active period of his 11-year cycle when solar winds strengthen. Because the corona appears larger during the maximum solar activity during a total solar eclipse, it was thought that there is a close relationship between the solar cycle and the temperature of the corona. But it may not be that simple.

In 2021, Habal and his colleagues published a study based on observations made during 14 total solar eclipses that suggest: The temperature of the corona does not depend on the solar cycle. The lines of the sun’s magnetic field can open and spread outward in the solar wind, or they can close and become hotter, forming a loop. “We found open magnetic field lines everywhere, regardless of the cycle,” Habal says. This means that the temperature of the corona is almost constant.

Observations have been impossible since 2019 due to bad weather. “In 2020 there was rain in Chile and in 2021 there were clouds over the Antarctic ocean, but in 2022 there was no solar eclipse,” Habal said.Team members are on an expedition to Antarctica. Benedict Justen Next time, he suggested, they could fly a kite equipped with a spectrometer that separates light into its component wavelengths.

A NASA-funded kite with a wingspan of 6.5 meters was successfully tested in Western Australia during a total solar eclipse in April 2023. It was launched on a kilometer-long tether attached to a vehicle. “It was truly miraculous,” Habal says. Due to bad weather, the team flew for the first time only 45 minutes before the total flight. “It was thrilling.”

This box-shaped kite will fly a NASA-funded scientific instrument to study total solar eclipses.

If the technology works well on future eclipses, more kites will be deployed in the future, and perhaps cameras will be added. “It’s much easier and cheaper than using balloons,” Habal says. But if things don’t work out, there’s always a backup.

During a total solar eclipse, two WB-57 planes will track each other just southwest of the eclipse’s maximum at 740 kilometers per hour, about one-fourth the speed of the moon’s shadow. At this speed, the total velocity increases from 4 minutes and 27 seconds to more than 6 minutes when viewed from the ground. “The WB-57 is perfect for this purpose because the nose cone has a built-in camera and telescope system that allows it to rotate and point at anything no matter what direction the aircraft is flying. ” says Mr. Amir Caspi At the Southwest Research Institute in Boulder, Colorado, he is in charge of the second WB-57 experiment to study the corona in a different way.

Caspi and his team will use a stable platform to image the eclipse using both a visible-light camera and a high-resolution mid-infrared camera developed by NASA. The latter captures light at seven different wavelengths and helps determine which structures in the corona are emitting their own light and which are just scattering light from the Sun’s surface. “To make these observations, we need to be as high up in the atmosphere as possible,” Caspi said. Infrared radiation is difficult to observe from the ground because it is absorbed by the Earth’s atmosphere.

Caspi is also part of the Citizen Continental American Telescope Eclipse (CATE) project. The project is an attempt to create a continuous 60-minute high-definition film using a team of 35 citizen scientists who travel a total path from Texas to Maine. They have the same cameras, telescopes, and training, so they can make exactly the same kinds of observations. “Each team will be spaced out so that each station overlaps its neighboring station,” Caspi said. “If one station can’t get data because of clouds or equipment failure, that’s okay.”

He is hopeful the device will work after it was successfully tested in Western Australia last year. “That was the first solar eclipse I ever saw,” Caspi said. He was busy live streaming on his YouTube, so he could only watch a few seconds. “Our devices couldn’t go online, so we spent the whole time holding our phones in front of our faces.”
