Being parasitised by a greater honeyguide is very bad news for a host – the young honeyguide stabs the host’s young to death with special bill hooks as soon as it hatches (more here). It’s therefore puzzling that little bee-eater hosts seem not to recognise and eject honeyguide eggs from their nests (more here). In this paper, we tested whether perhaps the sight of a female honeyguide (pictured) at the nest might give hosts a cue that they’re being parasitised and prompt them to defend themselves. The answer is that most bee-eaters seem bafflingly blithe! Read more in the original paper by Wenfei Tong, Nicholas Horrocks and Claire Spottiswoode, available open access in Ibis.
The Society for the Study of Evolution has awarded Jess Lund an R. C. Lewontin Graduate Research Excellence Grant, which will enable her to expand her investigations into the fascinating lives of honeyguides. This grant is awarded to students early in their PhD programmes to assist them in enhancing the scope of their research. Thank you to the SSE for their generous support of our work!
