On the public floor of the California Academy of Sciences is a direct tie into research and resources of many a variety and color. The Naturalist Center is located on the third floor adjacent to the exit from the planetarium. It is an often overlooked treasure. The Center offers a wide range of resources and services to individuals interested in learning more about the natural world. Academy visitors can walk in during open hours, explore the library, conduct research, and connect with staff members as well as other visitors.

Academy visitors can also ask questions about Academy exhibits or natural history. One day, when I was working in the Naturalist Center, a woman asked if squirrels eat bark and if so are they particularly fond of citrus bark? With a bit of research, we found out that some California-native squirrels indeed do eat bark and are fond of citrus trees. Below are some of the questions asked recently in the naturalist center, their corresponding answers as well as links to relevant fact sheets.

Q: Why is the green iguana orange? What do you feed it? (Visitor)

A: According to an Academy aquarium biologists, when males reach sexual maturity their coloring will turn orange. It's more hormonal than dietary, however diet can slightly influence color. The Academy has a male that is roughly three years old. He was rescued from a flea market as a baby in very poor condition. He is fed primarily greens (dandelion, collard, arugula) and small amounts of green beans, sweet potato, yellow squash, mango, berries, banana, papaya, cactus, and flowers along with a vitamin/calcium supplement.

Q: How much does the roof weigh?

A: It weighs between 2.7 and 2.8 million pounds not including the steel and concrete. More specific information is given on the Living Roof Fact Sheet: http://www.calacademy.org/newsroom/releases/2007/living_roof_fact_sheet.php

Q: How many African Penguins are in an average colony?

A: The number varies greatly and there is no true average. There are colonies with as few as 240 breeding pairs and one that was as high as 55,000 at one time. African penguin numbers have declined worldwide at an alarming rate in recent years. Decline in numbers is due to threats that range from oil spills to feral cats. Food availability and prime breeding territory are major factors in colony size as well. Today, there are an estimated 50,000 total breeding pairs worldwide.
