migrant birds more likely to winter over in fragmented sections of rain forest The migratory species in general seemed more resistant to change, more adaptable. This gives hope to their future survival but does not bode well for the resident species.
Along with tropical birds, one of the Smithsonian researchers looked at the connection of birds to army ants, which also inhabit tropical rain forests. Army ants are fascinating insects that have not changed significantly since the reign of the dinosaurs, about 100 million years ago. They are swarm raiders, foraging in colonies of up to 2,000,000 adult individuals in dense, fanshaped swarms that can span 10 to 30 feet across, attached to a temporary nest by a single column that can itself extend more than 600 feet. The Smithsonian researchers found three species of army ants in the study area.
