Actually I heard about it before it was published. In a local get
together of herps folks. Just mentioned in the chatter.

Add it to the frogs that communicate seismically.

Around here the highest frequency the frogs use is 7.5kHz, the smallest
North American frog, the Little Grass Frog. Many people hear higher
frequencies so poorly that they hardly hear that one. And even if they
do most would think it's a insect:
