We can’t offer our Halloween walk on Mount Diablo this year, but we can visit the devil mountain in spirit. Join us for a Zoom presentation spotlighting some of the nocturnal critters, spooky and otherwise, that call the Bay Area home.

We’ll see things that slither, crawl, and fly through the night when no human is around. How did owls get mistaken for flying ghosts, why do scorpions glow, and who put the poison in poison oak? Which tree is called the ghost pine and does it really grow witches’ brooms instead of cones? How is our greenbelt nightshift coping with climate change? Bring your candy bag and we’ll fill it with these and other nature tidbits.
