We seldom meet the wandering frog or see its crushed corpse on the road; on its nocturnal travels it usually dodges the dangerous wheel or boot. Yet the frog certainly covers considerable distances when seeking fresh feeding grounds. In my own garden there is one small area – very small – reserved for marsh plants and all summer this spot is guarded by two or three frogs; elsewhere in the garden frogs are mere casuals. There is no water in which tadpoles are reared in the immediate neighbourhood, and it is reasonable to suppose that the place is discovered by chance. The frogs vary in size, and sometimes a new arrival may be recognised. Small, medium-sized, and large frogs all seem to wander; the time of travel is apparently not confined to one particular age. Homing instincts of the batrachians have been studied, but this occurrence in a non-breeding but food-supplying spot suggests prospecting rather than homing. The wandering frogs hit on a good place, stake their claims, and squat. I hope that they will long continue to squat, for as a pest-destroyer few creatures can compete with a healthy frog.
