There are several species of small frog that live around the garden and by my lake. At night the calls are deafening, and I often find them in the grass or garden when working outside. These however, live in the Hydrangeas which are just outside my back door. They pretty much vanish through the winter, but at this time of year there are many young ones to be found amongst the leaves. They are Littoria ewingii or Southern Brown Tree Frogs and the adults only reach about 45mm in size. These ones are tiny, about the size of a finger nail, and to give you an idea, one in the photos below, is sitting on the underside of my little finger. As usual, click on an individual photo to enlarge it.
