Hampshire house martin nests scheme expanded to combat decline in threatened birds
Free nests offered across Hampshire
The Hampshire House Martins Project is offering artificial nest cups following a pilot scheme. The cups are made from woodcrete, described as stronger and more durable than mud.
In the pilot, 249 cups were fitted to buildings near known nesting sites in northern and eastern Hampshire. The expanded project could provide up to 900 cups. Homeowners, schools and businesses can apply, provided buildings have suitable overhanging eaves at second-storey height, four to seven metres above the ground.
Reasons for the population decline
The UK house martin population declined by 40% between 1995 and 2024. Poor breeding success is cited as one factor in the fall. Fewer insects and hotter, drier weather have also been blamed. Reduced availability of wet mud can make it harder for the birds to build nests. House martins return from Africa each April and May to spend summer in the UK.
Survey helps locate nests
Last year, the Hampshire Ornithological Society launched a public survey to record where house martins nest. The information helps identify buildings near existing nesting sites for the project.
Society chair Keith Betton said the first pilot stage showed strong interest from people across Hampshire. He said the scheme gives homeowners, schools and businesses a practical way to support the threatened bird's recovery.
