Collared Flycatcher (IMAGE) Uppsala University Caption The European pied flycatcher, and later its close relative the collared flycatcher, have long been an important research organism for scientists at many universities. Their nesting (and thereby reproductive success) is rather easy to observe, as they readily inhabit deployed birdhouses. Over the years research from Uppsala University, Sweden, has laid a foundation for understanding many general aspects of ecology and evolution, with multiple doctoral dissertations and acclaimed research reports.
