Manakin Birds of Central America (IMAGE) University of Miami Caption In relatively recent times in the evolution of life, some manakin birds of Central America split into two groups. White-collared manakins occupy the area from Mexico to Panama, while yellow-collared manakins live between Panama and Colombia. Males are colorful, while females are brown. The two species meet in northwest Panama and form leks together, which gives scientists the opportunity to see what happens when new species reunite.
