Nature lovers can join Bird LA, Audubon California, Audubon chapters, and a huge collection of other cool groups for a super fun, de-centralized, all-day celebration of birds all over LA County.
The bird walks and events are too numerous to detail here, but a few highlights include:

• an Open House at International Bird Rescue in San Pedro
• an all-ages hike in Griffith Park
• a tour of bird songs in the UCLA Mildred E. Mathias Botanical Garden.
• a family fun day at Rancho Santa Ana Botanic Garden

The website has a map showing the many events throughout LA.
