If you can manage a pond in your garden, the birds will love it. Blackbirds and garden birds will bath in it, fluffing up their feathers for a good wash.
I took the image top centre of a Wagtail tit on a lily in my garden pond. A common visitor, bobbing across the lily pads looking for insects, of which there are always plenty in a pond.
An uncommon visitor is in the image left, which is not the best quality but a magical moment. Rarely is a Kingfisher seen in a garden setting and I just grabbed the camera. On two separate occasions, the Kingfisher arrived and flashed his beautiful blue for just a few seconds.
More commonly found around ponds are a host of wildlife including: many birds to bathe and drink, damselflies and dragonflies in abundance, frogs and toads, mammals for drinking such as foxes and badgers, Invertebrates such as pond skaters, water boatman and water beetles, which in turn attract more birds to feed on the insects.
