Submitted to the Tribune The Tahoe basin is known for its many different animal species that live in the area. One of the more popular species in the region is the chickadee, with many locals and tourists making the trek to Chickadee Ridge summer and winter to feed the birds. Aside from the free handouts the birds on Chickadee Ridge receive, how do the chickadees survive year-round in the Tahoe basin? Join Tahoe Silicon Mountain, a local network of entrepreneurs and professionals, at 5 p.m. Monday, Feb. 8, to hear Ben Sonnenberg speak on the natural selection and spatial cognition in wild food-catching mountain chickadees.
