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.

Dr Gabriel Jamie and Professor Claire Spottiswoode of the African Cuckoos team, together with Professor Anusuya Chinsamy-Turan, have just finished teaching an Honours (4th-year undergraduate) module on "Fundamentals of Scientific Research" at University of Cape Town....

The African Cuckoos Team had a fantastic time at the Pan-African Ornithological Congress (PAOC15), this year held in Vic Falls, Zimbabwe. Dr Chima Nwaogu gave a plenary talk on “Differing Priorities in the Timing of Annual Life History Events”, while Professor Claire Spottiswoode and Silky Hamama presented during a roundtable session on communities in conservation and research. Silky also presented a poster, with Claire, Jess Lund, Mairenn Attwood and Cameron Blair each giving research talks as well. 

Dr Gabriel Jamie has just returned from a successful couple of months of fieldwork in Zambia as part of his Leverhulme Early Career Research Fellowship. For this research, Dr Jamie is exploring the evolution of polymorphisms across diverse avian family Cisticolidae which exhibit some of the most complex and diverse eggs of any group of birds in the world.
