Can you host a House Martin cup?
Lewes Swift Supporters are interested in hearing from anyone who lives in a house in Lewes where House Martins have built a nest in the recent past.
Having already installed almost 200 Swift nest boxes, they have funding to provide and some install artificial House Martin nest cups.
Like Swifts, House Martins are also on the red list of birds of conservation concern. A factor in their decline is thought to be the dry springs and summers, which prevent them from finding the mud which they need to build resilient nests.
