Gigaciconiidae is the Apex Migrator on earth. It is a species of bird from the Macroavian clade, occupying the highest trophic level on the planet. It migrates to equatorial waters by mid-autumn. Many bird species benefit from their migratory practices while keeping pests off from its body. This mutualistic behavior makes it possible for many species to strive, where otherwise, they would be preyed upon. Human development on its migration course is impossible. It's existence simply gave birds the reproductive, and survivalist upper hand.
It dominates the earth, sea, and sky with its wide wings and powerful screech; having no natural or possible synthetic predator, makes them more than animals: they are Gods.
