An ostrich chick hatches from its shell.
Ostriches, originally from Africa, are close kin of emus, from Australia, and rheas, from South America. The flightless birds evolved after the supercontinent Gondwana was torn apart by tectonic shifts in our planet’s crust. See ostrich chicks and learn how earth movements shape life in the exhibit Earthquake, opening May 26 at the California Academy of Sciences in San Francisco. (415) 379-8000, calacademy.org.
