To what extent do birds in a habitat like this make use of the drainage lines as highways? That is a question that interests us!

Spanish omelette

These ringing blogs often lapse into a focus on food. This one is no exception. Two interns from the Basque Country in Spain, Ana and Iñaki, treated us to tortilla de patatas, aka, Spanish omelette.

Although citizen science in biology is Les’s passion, his academic background is in mathematical statistics. He was awarded his PhD in abstract multivariate analyses in 1973 at UCT and what he likes to say about his PhD is that he solved a problem that no one has ever had. He soon grasped that this was not the field to which he wanted to devote his life, so he retrained himself as an applied statistician, solving real-world problems.
