If you call a bird, will it answer? This is a question that participants of Family Adventure Day: The Birds of Beauty Ranch will be invited to explore. At the event, kids can make simple bird calls from everyday items and then test them out on a naturalist-led walk. After the hike, there will be visits with live raptors and then art-making. The day, which is open to children of all ages, will be held on October 19, 11 a.m.–2 p.m., at the Jack London State Historic Park in Glen Ellen. While the event is free, the regular park admission fee of $10 per vehicle applies. See jacklondonpark.com/events/family-adventure-day-2 for more information.
