The story of a six-month expedition by naturalist-explorer Jeffery Boswall from the Sonora Desert where animals and plants endure temperatures of well over 100 degrees Fahrenheit, south to islands in the Sea of Cortez and off the Pacific coast, and to steaming mangrove swamps.
See giant, 50-foot tall saguaro cacti, colourful Heermann's gulls, massive elephant seals and graceful Californian sea lions, and, in the swamps, courting boat-billed herons and a bird that eats crabs.
The expedition moves further south to one of the last tracts of tropical rain forest in Mexico with its giant millipedes and beetles, noisy howler monkeys and agile spider monkeys, and finally on to a remote coral reef in the blue waters of the Gulf of Mexico where tropical fish live amongst wrecked ships and lost migrating birds find refuge on the coral islands.
The best from an original series of six films.
