It is explained to the audience that they are to try and guess the name of well known local birds that will be acted out. Then, members of the patrol enter singly or in pairs, in quick succession and mime the name of a bird. The cornier the acting, the more the audience will love it. Bird names that will lend themselves well to this bird brain treatment are puffin, swallow, robin, raven, crossbill, nightjar etc. Three or four birds are sufficient.
