Incipient loss of a rainforest mutualism?

© 2017 Johannes H. Fischer, Heiko U. Wittmer, Endro Setiawan, Sarah Jaffe, Andrew J. Marshall. We use data from motion-activated remote cameras to document a commensal, and possibly mutualistic, relationship between Bornean Ground Cuckoos and Bearded Pigs in the rainforests of Kalimantan, Indonesia. We hypothesise that birds benefiting from symbiotic relationships may suffer indirect detrimental effects from hunting that targets large mammals in tropical rainforests.
