In early 2016 we installed duck nest tubes in an agricultural area in the western part of the Netherlands to provide safe nesting sites for mallards. The design of these nesting tubes was inspired by previous projects in the US and Britain. We are excited to learn whether these artifical nesting sites also work in the Netherlands! A brief impression below.
Already after two days we had our first inspection of a duck nest tube!
