Still 23 April 2016 in Extremadura, Spain. From the hide near Jaraicejo one cannot only see the bee-eaters mentioned on this blog earlier. There are also spotless starlings like these ones, trying to squat in tunnels dug by bee-eaters in their nesting colony.
Sometimes they make lots of noise and spread their wings.
Sometimes they behave more quietly.
Sometimes they sit on a branch close to the hide.
