 P. exclamans has several different predators . Their most dangerous predators are birds , which will fly by and knock the nest to the ground . This phenomenon was discovered by the disappearance of nests , and wasp nests being found on the ground near the bird ’ s nest . It has also been found that birds eat the larvae from the P. exclamans nest . This attack kills the whole nest but it isn ’ t very effective against the adults from the colony . When attacked , the adults fly away either to another colony or a satellite colony .
