Infections with parasites often entail no recognizable signs in many wildlife species, but can have still negative effects across generations. Infected animals often have a slightly reduced body size and their offspring have a harder start in life. A team of scientists has now shown that the impaired reproductive success is connected to altered movement behavior: Infected starlings have a smaller action radius, which limits their access to high-quality foraging habitats.
