Beaks, bugs and evolution.

In order to investigate evolution and adaptations, Larch class took on the roles of spoon-beaked, fork-beaked and pencil-beaked birds in different environments. The population of spoon-beaked birds quickly fell as they were unable to scoop up pasta bugs from small places. Our sharp and thin pencil-beaked birds brought bark-based bugs out of their habitat much more easily, and therefore became more common!
