I must admit I have a bit of a passion for the wildlife of rivers and Sand martins and Kingfishers are two of key species of our UK waterbodies. Most people know what a Kingfisher is but I have learnt recently that Sand martins are it seems a little bit unknown and I have found many people looking puzzled when I have explained we have built them an artificial nesting site.
|What we came to call the bible!|
6. With the front board tempoaryly on a template could be draw around the block holes. Then we we could cut out the randon located nesting entrances.
7. Nesting pipes 70cm long and 127mm in diameter. Pipes backed with plastic bags and attached with cable ties. Once pipes are in place they can be half filled with sand and then the front board bolted in place.
8. Once the artificial nesting site was complete, we filled up the natural nesting bank with a layers of 50/50 sand/soil at a ratio of 50:1 dry cement. A temporary front board was put up to support the back filling of these layers of sand, soil and cement. We then left the front board on for about a week to allow the dry cement to go off, which has left a really hard bank that we hope is similar in structure to a riverbank.
9. Once all the bank was in place, we set to and painted the rendered walls and front board to give it a more natural look and I finished it off with a Sand martin silhouette painting.
