In The Wind Birds: Shorebirds of North America, nature writer and novelist Peter Matthiessen wrote: “The restlessness of shorebirds, their kinship with the distance and swift seasons, the wistful signal of their voices down the long coastlines of the world make them, for me, the most…

Thanks to radio transmitters, scientists have vastly increased their knowledge of Red Knot migration patterns. For example, the vast majority of Red Knots on the Pacific Coast rely on a small number of places to rest and feed during spring migration from Mexico to the Arctic. Those…

The Hoatzin is a strange bird, indeed! It looks like it was put together by a committee. But the way it looks isn't the only thing that sets this bird apart. The Hoatzin is strictly a leaf-eater, filling its stomach with leaves, and then resting and digesting for long periods. Chicks have…

Gordon Hempton, the Soundtracker, likens the joy he feels after a day of recording Western Meadowlarks (their eastern cousin is seen here on the left...) to the experience of John Muir, who knew individual American Dippers (also known as Water Ouzels; seen here on the right) by their songs…

Nature shows set in Africa often show rhinos and other large mammals with small birds on their backs. They're oxpeckers — like the Yellow-billed Oxpecker pictured here. This relationship was long held up as a textbook example of mutualism. Oxpeckers feed almost exclusively on whatever they…

The call of the Pied-billed Grebe is unusual. Their nests are unusual too – little platforms of plant material that float on water, hidden behind vegetation. Martin Muller, an expert who loves unraveling the mysteries of Pied-billed Grebes, explains how grebe parents like this one build…

Among the most feared weapons deployed in World War I, submarines sank almost 5,000 ships, sending 15,000 sailors to watery graves. Scientists and navy men worked to come up with a way to detect enemy subs. One thought was to feed wild gulls from a dummy periscope, in the hope that the…

Bobolinks breed in North America and winter in South America. Like many songbirds, they’re classic long-distance migrants. But some Savannah Sparrows fly far south in winter, some fly not so far, and some stay put. This mix of strategies is known as “differential migration.” Sometimes…

April 1 - High above the clouds caressing the upper reaches of the mountains soars the most majestic bird you are never likely to see or hear: the Semi-Fixed-Wing Silver Delirian. With a wingspan of some four yards, a sleek metallic silver body almost as long as its wingspan, and huge…
