Unique Animal Behaviors Observed During Partial and Total Solar Eclipses in Different Seasons

On April 8, a total solar eclipse will present a new opportunity for researchers to observe the behaviors of animals at the Fort Worth Zoo in Texas. This eclipse, occurring in a different season and route than the one in 2017, will allow scientists to study potential impacts on spring migration and observe how animals' routines are disrupted when skies dim.

New Insights on Animal Reactions to Eclipses

While there have been individual sightings of animals behaving strangely during historic eclipses, rigorous scientific studies on the altered behaviors of wild, domestic, and zoo animals have only recently started. Researchers observed Galapagos tortoises at the Riverbanks Zoo in Columbia, South Carolina, displaying uncommon breeding behavior during the peak of the eclipse. Additionally, gibbons sang unusual tunes, male giraffes exhibited apparent anxiety by galloping, and flamingos huddled around their juveniles. These behaviors are believed to be connected with an early dusk, displaying changes in their natural routines. Spring migration patterns will also be studied to see if there are any larger patterns among animal species.

Eclipse Effects on Honeybee Colonies

University of Tennessee entomologist, Jennifer Tsuruda, observed honeybee colonies during the 2017 eclipse and noted decreased foraging, similar to their behavior at night. This conflict between internal rhythms and the external environment affects the bees' navigation as they rely on polarized light from the sun to find their way.

Impacts on Wild Species and Birds' Migration

Eclipse researcher, Nate Bickford, mentioned that solar eclipses mimic short, fast-moving storms where animals take shelter. Data showed that flying bald eagles changed their speed and direction during the eclipse, as well as feral horses adapting to the possibility of a storm. Researchers plan to analyze weather radar data during the upcoming eclipse to see if more birds take flight, potentially mistaking the eclipse conditions for nighttime migration cues.

Effects on Indoor Pets

University of Arkansas animal researcher, Raffaela Lesch, pointed out that indoor pets may react to their owners' behavior as much as to any changes in the sky. Dogs and cats are sensitive to their owners' reactions and internal clocks, making them potential subjects for studying human-animal interactions during eclipses.
