Dr Gabriel Jamie and Dr Chima Nwaogu organised a symposium on “The ecology and evolution of moult in tropical birds” as part of the International Ornithological Congress. The symposium included a Round Table discussion as well as invited talks from a range of speakers including Dr Yahkat Barshep (A. P. Leventis Ornithological Research Institute, Nigeria), Dr Barbara Helm (Swiss Ornithological Research Institute, Switzerland), Dr Oluwadunsin Adekola (FitzPatrick Institute of African Ornithology, University of Cape Town, South Africa & Federal University of Technology, Akure, Nigeria) and Dr Yosef Kiat (University of Haifa, Israel).
New paper on imperfect egg mimicry
Our paper “Combined measures of mimetic fidelity explain imperfect mimicry in a brood parasite-host system” has just been published in the journal Biology Letters. This study was led by Tanmay Dixit, and carried out together with Gary Choi, Salem al-Mosleh, Jess Lund, Jolyon Troscianko, Collins Moya, L Mahadevan, and Claire Spottiswoode, as part of a collaboration between our group and Prof. Mahadevan and his lab at Harvard University. Together we combined mathematical tools and field experiments in Zambia to quantify a key difference – “squiggle” markings – between the eggs of hosts (tawny-flanked prinias) and parasites (cuckoo finches). We showed that suboptimal behaviour on the part of prinias allows cuckoo finches to get by with an imperfect copy of prinia eggs.
