Female Cope’s gray tree frogs (Hyla chrysoscelis) prefer males with longer calls, which in some tree frogs is tied to better survival odds for offspring.
But female frogs exposed to an overabundance of mating calls are worse at picking out the best mates, researchers report August 12 in iScience.
This suggests that, like people, frogs experience choice overload — the tendency to delay, avoid and make worse decisions when more choices are offered.
In this latest study, researchers captured 60 female frogs in the middle of mating from ponds around Knoxville.
Female frogs simply “can’t always get what they want.”
