When you sign up for a birding excursion with Mary and Nick Freeman, you may find yourself learning a lot more than you expected. In addition to bird identification by color, features, calls, and habitat, you may learn about flora and fauna, geology, biology, and even archeology. That’s because the folks who tend to go on their trips are amazingly diverse in their backgrounds and happy to share their knowledge. On a recent four-day Owens Valley sage-grouse trip led by the Freemans, the dozen attendees included two biologists, a geologist, an archeologist, and birders and photographers of all levels, including one world birder whose life list encompasses more than 7,700 birds!
