A Jekyll-and-Hyde Act for the Feathered Set

Honeybirds or Honeyguides are birds that guide humans to beehives. After we finish taking all the honey that we need they feed on whats left but not everything is good when it comes to these birds. Studies have shown that these birds are also parasites with a bad side. Honeyguides lay their eggs in the nests of a bird called the bee eater. When a honeyguide chick hatches, it jabs its beak into its foster siblings and shakes them until they die. At that age the birds are blind but they still commit their brutal murders.Remarkably, they also found that the baby honeyguide can mimic the call of an entire brood of bee eaters. After killing its foster siblings, the young honeyguide misleads its foster mother into thinking that she is still nurturing her own chicks. Which is amasing, as an effect this honeybirds are dramaticaly changing the population of other birds. The honeyguide appears to exhibit this parasitic behavior in the nests of at least four other species of birds. Dr. Spottiswoode  the leader of the study is studying how it has evolved the unique adaptations that allow it to exploit each host species.
