Theodore Cross, the founder of Birders United and the author of Birds of the Sea, Shore, and Tundra, has authored a new book which is available from W.W. Norton Company. Cross’ photographs include birds from four continents. From the tundra of eastern Siberia to the tropical islands of the South Pacific, Cross has captured elegant and unusual birds—from auklets and egrets to gannets and sanderlings—in peak action, be they courting, landing on a perch, plunge diving, or engaged in aerobatics.
The 179 color photographs in this 344-page book are accompanied by gracefully written field notes and fascinating accounts of the birds’ habits and habitat.
