Nakuru: land of clever birds with tiny glasses
…or at least that’s how I would paraphrase my dear friend Andrea Liebl’s research. She has made her annual trek back to Kenya to study house sparrows. House sparrows are an invasive species on nearly every continent (except their native Eurasia) and were introduced to Kenya in the 1950’s in Mombasa. Andrea has a hypothesis that birds on the “invasion front,” those intrepid birds furthest from their introduction, are smarter and respond better to stress than do the home-bound populations who have remained in Mombasa for 60+ years. Visit her blog for more info, pictures of her glamorous field work, and frequent updates.
