A Role for Parasites in Cooperative Behavior (2 of 2)

Loading video...

Caption: Fairy-wrens are cooperative breeders. They are parasitized by cuckoo species. Here, superb fairy-wrens attack a model bronze-cuckoo, which has been placed inside a cage to protect it from damage. This video relates to a paper that appeared in the 20 Dec., 2013, issue of Science, published by AAAS. The paper, by William Feeney at The Australian National University in Canberra, ACT, Australia, and colleagues was titled, "Brood Parasitism and the Evolution of Cooperative Breeding in Birds."
