Steller's Jay "Anting" at Humboldt Redwoods State Park
Steller's Jays (Cyanocitta stelleri) aren't rare, but the one we saw at did something a bit odd. It spread out its wings and flattened itself onto the fence. I didn't understand what was going on at the time, but I later found that it was probably "anting". The bird may be spreading ants on its wings as a way of making a chemically hostile environment for mites and other parasites.
Steller's Jays are a familiar sight in western conifer forests, with a range that extends from Central America to Alaska. They are almost never found at my home in the Central Valley, but it is a rare trip to the local mountains that doesn't have a sighting or two or a dozen. They are the most common nuisance bird at campgrounds and picnic areas with the possible exception of Common Ravens.
Humboldt Redwoods State Park preserves some beautiful old-growth Redwood forests along the so-called Avenue of the Giants (an old section of Highway 101 repurposed into a tourist route). It's a wonderful cool destination when the temperature soars in other parts of the western states.
