Humans generally like their animals cute and cuddly. But Sonoma County Regional Parks staff think that the not-so-cute critters are pretty interesting, too. At the Ugliest Animal Countdown, kids can participate in a funny roast of the least attractive animals in Sonoma County, and learn why, despite their appearances, they are important to the ecosystem. This free event will be held on December 4, 10 a.m.–noon, at Foothill Regional Park in Windsor. Parking is $7. Go to tinyurl.com/9rn296t6 to learn more.
