The island is well provided with fresh water by a well located halfway between the cottage and the dock. In this space there is also small pond surrounded by reeds and some small tree cover, and from this pond issues a stream flowing down into South Haven below. This is one of the 4-5 locations for the mist nets, used to catch small birds for ringing.
There are sedge warblers all over the island and the song of these lovely birds is strong and cheerful. I watched as one singing on small tree rose up and up singing ever louder, before alighting on another shrub and doing it all again. It seemed so large in song. The next day I was treated to an up-close view. One had been caught in the mist nets and was being ringed, checked and recorded. I was surprised at how small it seemed. Motion and song add significantly to our perception of size.
