Bears take a beating in hot weather.
They huff and puff and seek water where they can cool off.
They wallow and tank up at any time of day or night, but during really hot weather they may visit the same pool several times a day.
"Shedding thermal energy" is biological techno-jargon for the various ways animals cool off.
I learned that from a "physiological ecologist".
It's hard to shed thermal energy if you are big and fat like a bear, because of the large surface-to-volume ratio.
Anyway, I've learned a few things from viewing hundreds of 30 second video clips of bears visiting water holes here in Butte County.
You'll notice that I've also moved the camera closer to center stage.
This video introduces "Tank", and one of these days I'll post a video of the full cast of Bruins here.
