Why do many migratory bird species that breed in Europe sing extravagant songs on their wintering grounds in tropical Africa, thousands of miles away from where they attract their mates? Dr Marjorie Sorensen‘s PhD field research on great reed warblers (left) in Zambia points to an intriguing answer: they’re practicing!

Tanmay Dixit was a member of a team organising and lecturing in the inaugural Evolutionary Biology Crash Course. This course, aimed at undergraduate or early-postgraduate students, teaches evolutionary principles to students who have had limited opportunities to be exposed to evolutionary ideas. The course is funded by the Equal Opportunities Initiative Fund of the European Society of Evolutionary Biology (ESEB). Tanmay presented lectures on behavioural ecology and evolution, focussing on kin selection, coevolution, and parasitism. Over 700 students, with the vast majority from the global South, attended the course, which was a resounding success!
