A System Benefiting Birds, Ants, and Trees

Birds have an interesting method for keeping ants out of their nests and away from their eggs and chicks. Many ant species will eat everything in their path, and often, ants infect trees where birds build their nests. From a design standpoint, how can you build a system benefiting birds, ants, and trees?

Scientists have discovered that in tropical and subtropical areas, birds use fungal organs known as rhizomorphs to build their nests. Rhizomorphs are cord-like filaments that fungi use to capture nutrients, and they grow web-like in the canopy of tropical forests. These filaments repel ants to keep them out of the birds’ nests. Researchers have found that over 176 bird species use fungal rhizomorphs in their nests. Two bird species in Costa Rica build their nests almost entirely using rhizomorphs of horse hair fungus (Marasmius).

Researchers in Costa Rica found a symbiotic relationship between thorn acacia trees and ants. The ants collect nectar from the acacia, repel any invaders, and even trim back encroaching plants. The thorns of the acacia protect the ants from predation, and the rhizomorphs protect the birds. This complex system benefiting birds, ants, and trees is very difficult to explain by any chance process. The concept of God building a system that protects all three participants is simply an argument for His existence.
