In the space of a few months we saw a myriad of different insects take to the pond, and I'm hoping they will encourage other animals like newts to eventually make it a home. We now have one frog which seems to be a permanent resident (hopefully he/she will encourage others to join!). We have a large variety of bird species that come to the feeders every day, my particular favourites being the woodpeckers and Goldfinches. We even get fairly regular visits from a Sparrowhawk (I'm still to get a decent photo of it).
Finally my favourite species that now calls the garden home is our resident hedgehog. I consider us very lucky to see a once common, now rare, species every night, and I'm doing all I can to help them, including leaving a little bit of food out every night, and installing a 'hedgehog house' complete with wireless camera so I can watch what goes on without disturbing them.
