Landing and perching on a branch is easy for most birds, but it is very difficult for robots that fly like birds because of their larger size and the complexity of landing on a thin object.

Now, Raphael Zufferey at the Swiss Federal Institute of Technology in Lausanne and his colleagues have developed a robotic bird – which has a 1.5-metre wingspan …
