Cuckoos and their victims: An evolutionary arms race

14 May, 2015 @ 6:00 pm - 8:00 pm

Free

The sight of a little warbler feeding an enormous cuckoo chick has astonished observers since ancient times. It was once thought that cuckoos were unable to raise their own young because of defective anatomy and behaviour, and so other birds were only too delighted to help them. This quaint view was overturned by Darwin, who suggested that the cuckoos’ parasitic habits were advantageous and that their host species were tricked.

Discover how field experiments and genetic studies reveal an ongoing evolutionary arms race, in which escalating host defences have selected for remarkable cuckoo trickery, including: different guises in female cuckoos, cuckoo forgeries of host-egg signatures, and manipulative begging by cuckoo chicks. This is a fascinating corner of Darwin’s “entangled bank”, where organisms are forever evolving to keep up with changes in their rivals.

The Croonian Lecture series began in 1736 and is the premier lecture in the biological sciences. Professor Nicholas Davies FRS was awarded the 2015 Croonian Lecture for his work on the co-evolved responses of brood parasitic cuckoos and their hosts, the process of co-evolution and adaptation and the extraordinary biology of these unusual birds.
