<b>Celebrating Earth Day at Iron Horse Vineyards:</b> On Sunday, Iron Horse Vineyards (9786 Ross Station Road, Sebastopol) celebrates Earth Day in Green Valley with a very special keynote speaker, Supreme Court Justice Sandra Day O'Connor.
This "Eat, Drink and Be Green" fete features a tasting of Green Valley wines, including Marimar Estate, Dutton-Goldfield Winery and several others, and a local feast prepared by chef Douglas Keane. There will be a display of environmental art, a presentation by Silicon Valley Robotics and a performance by Trio Elias, an all-female mariachi band from Los Angeles.
Cost of the main event is $65. To attend a private reception for Justice O'Connor with Iron Horse bubbly and caviar from California Caviar, you'll need to pony up $300.
As of press time, there were still tickets for both events. To join in, visit ironhorsevineyards.com.
<b>Festival of Feathers:</b> The Bird Rescue Center hosts its second annual Festival of Feathers on Saturday from 11 a.m. to 4 p.m.
Nearly two dozen resident raptors — birds that, for various reasons, cannot be returned to the wild — will participate, offering opportunities for guests to see these birds of prey up close.
In addition, there will be yummy appetizers, snacks, desserts and beverages, including wine. A silent auction features a mix of services, getaways and more.
Birds around the world are struggling, and local organizations like this one do so much to help, not just with individual birds but with the education of humans, essential if threatened species are to survive.
The Bird Rescue Center is located at 3430 Chanate Road, Santa Rosa. It is open daily, year round. For more information, call 523-2473 or visit www.birdrescuecenter.org.
<b>Speaking of Feathers:</b> On May 3, the Laguna de Santa Rosa Foundation hosts Rookery Walk, a guided hike to a bird nesting colony at Delta Pond.
Nesting birds include great blue herons, double-crested cormorants and great egrets, all in their breeding plumage.
There are five walks, at 8 a.m., 8:15, 8:30, 8:45 and 9.
Cost is $15 per person, and if you want to join in you should sing up today, as the number of participants is limited and these annual walks are very popular.
