Talk of transatlantic flights! The golden plover makes a non-stop flight of 2400 miles from Nova Scotia to the northeast coast of South America, and has been doing it for centuries without ever getting a line of publicity in the newspapers. The night-hawk nests in the Yukon and winters in Argentina, 7000 miles away. Nineteen species of shore-birds rear their young north of the arctic circle and then fly to South America, six of the species even penetrating Patagonia, 8000 miles from their northern nesting grounds. The far-famed bobolink of New England migrates to Brazil, making a transoceanic flight of 700 miles from Cuba to the South American coast. So also do the purple martins, cliff-swallows, barnswallows, and some thrushes.
