Stretching from the Bering Strait off the coast of Alaska to the southernmost tip of South America, the Pacific Flyway ranks as one of the greatest migratory pathways in the world. Millions of birds representing hundreds of species use this great avian highway each year, and nowhere is this abundance of wildlife more accessible than right here in Butte County.
Winter Birding
With an ideal combination of mild winter weather, and abundant food and water, the area attracts a huge wintering population of waterfowl and raptors, making it an ideal location for Northern California birdwatching.
This migration, especially of the majestic snow goose, is celebrated annually at the end of January with theSnow Goose Festival of the Pacific Flyway. The four-day celebration includes field trips, workshops, exhibitions, and other activities revolving around a variety of geese, ducks, herons, raptors, and more, all in their natural splendor.
Even if you can’t make it to the Snow Goose Festival, you can still enjoy spectacular birding opportunities whenever you visit.
The viewing platforms at the Llano Seco Unit south of Chico provide what is arguably the most spectacular wildlife viewing in Northern California. On the elevated platforms, you’ll be overwhelmed by the number of birds you can see, including unusual migrating species in the fall, like the black-bellied plover, and less common duck species, like the Eurasian Wigeon, in the winter.
In Gridley, the Gray Lodge Wildlife Area is perhaps the most well-known birding site in Butte County. The well-marked nature trail makes for a refreshing walk with spectacular bird viewing of more than 230 bird species across the 9,200-acre wildlife area. During the winter migration, you’ll likely be rewarded with a dusk “fly-off” of thousands of Snow Geese and other waterfowl filling the sky. You can also enjoy an exhibit museum, seasonal tours, and excellent car viewing.
Spring Birding
In the spring, you’ll find trees jam-packed with warblers, vireos, tanagers, and grosbeaks at the Big Chico Creek Ecological Reserve. For something a little different, a trip to the Chico Oxidation Ponds will likely showcase rarely seen southerly migrating species, such as the semi-palmated sandpiper. Access to the Oxidations Ponds are only available through guided trips held by the Altacal Audubon Society, so follow them on Facebook or view their field trip calendar for announcements about upcoming fieldtrips.
—just make sure to call ahead for permission. In Oroville, the Thermalito Afterbay and Thermalito Forebay provide great vantage points for viewing waterbirds as well as more rare raptor sightings than anywhere else in the area.
Fall Birding
Other birding opportunities are abundant in the fall, when a variety of species make the return migration from their mountain breeding spots and become easier to spot as the trees lose their leaves.
Trip Tips
Seasoned birders know that anyone can get into this easy activity, and that it’s a great way to explore places you’ve never been! Here are a few tips to get you started:
Wear comfortable walking shoes, bring binoculars, and download a birding app (or use the Explore Butte County fall and winter birding brochure)
Dress for the elements and the season
Respect the habitat and minimize your footprint so that everyone can enjoy the space
