Birds of a Feather, Fashion Together

There are two types of migration, voluntary and involuntary.

An example of the enforced kind would be animals leaving a decimated rainforest. The chosen type takes place in the Bay Area, where Chapeau Chic femmes, descend on the Rotunda restaurant (at Neiman Marcus) and host a luncheon for the San Francisco Zoological Society Auxiliary.

These ladies don't move for climate reasons -- but for a cause. In what has become a seasonal migratory event (for the couture clan) its purpose is to connect people with wildlife, to inspire caring for nature and advance conservation action; in addition to benefitting the zoo's Koret-Taube Aviary. All while decked out in the season's best ensembles and eye-catching hats.

The flock of stylish femmes were greeted and graciously hosted by Lori Shigekane, Charley Zeches and Mindy Henderson. It was an uplifting exploration of psychology, zoology and what truly defines an "Exotic Bird."
