With two new penguin chicks arriving at California Academy of Sciences late last year, Academy biologist Holly Rosenblum gave the Total SF team a behind-the-scenes tour — and an exclusive interview with the baby birds. Also in this episode, hosts Heather Knight and Peter Hartlaub announce their new quest to find an official animal of San Francisco (the penguins are nominated!) and Rosenblum explains the international breeding program to save the African penguins — which includes travel on commercial flights. Learn more about the African penguin colony and the best time to visit at calacademy.org Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb. Follow Total SF adventures at www.sfchronicle.com/totalsf  Learn more about your ad choices.
