75% of Animal Species Change Behavior During Total Solar Eclipses, Multi-Continent Studies Show

Studies across multiple total solar eclipses found roughly 75% of observed animal species alter behavior during totality. Diurnal species shift to evening routines — bees return to hives, birds stop singing — while nocturnal ones activate. The consistency across continents and taxa indicates circadian rhythms respond to light thresholds, not time of day alone.
