House Martins are declining in Hampshire. Using the menu above, please tell us where you see them nesting, so that we can monitor the population and help them breed more successfully.

The Hampshire House Martin Project is a citizen science initiative aimed at anyone who has seen House Martin nests in Hampshire. It aims to raise awareness about House Martin declines, build our knowledge of nest sites and prepare the ground for a possible county-wide survey and the provision of artificial nest cups in future years.
