The first national survey of sand martins in Estonia was organized by the Estonian Ornithological Society in the summer of 2017. The study aimed to estimate the size of the breeding population, map their distribution and sample the breeding success in different types of colonies. In 2018 the project will introduce for the first time in the country management measures for sand martins in mineral extraction sites.
Once you have found a good habitat one has to think about other life challenges, predators and rivals, to name a few. For a third year, the Polish aggregate producer Górażdże and OTOP\BirdLife Poland work together on a number of wetlands in Southern Poland to improve local populations of Black-headed and Mediterranean gulls and Common Terns.
