When the Birds Fly South is Stanton A. Coblentz's imaginative science-fantasy classic, weaving together romance, exploration, and mythic wonder. The story follows Dan Prescott, an adventurer who discovers a secluded valley inhabited by the Irrwane-a mysterious race of winged people who migrate with the seasons. Drawn into their world, Dan becomes immersed in a society shaped by ancient customs, natural harmony, and the instinctive call of flight.
As he grows closer to Azil, one of the winged women, Dan confronts the limits of human life, the pull of love across worlds, and the eternal tension between personal desire and the unchangeable laws of nature. Coblentz's lyrical prose and vivid world-building make this novel a standout work of early speculative fiction.
A landmark of science-fantasy literature, When the Birds Fly South continues to captivate readers who enjoy lost-world adventures, mythic storytelling, and classic speculative narratives.
