Winter 2016

The January-March issue takes readers to the streets and parks of San Francisco where the evolving songs of white-crowned sparrows are the subject of ground-breaking studies thanks to 50 years of data. Plus: Dark, cold, and oxygenless ocean water may be invading our Bay; the beguiling and unexpectedly philosophical existence of lichen; a paddling trip through the long-fought for and newly restored wetlands at Cullinan Ranch on San Pablo Bay; as well as a look at the ladybugs that huddle in our hills.
