On the north bank of the River Kelvin in Garscube Estate. This strange-looking construction, completed in March 2021 is for sand martins to nest in. Glasgow University’s Urban Biodiversity Working Group obtained funding from the Blodwyn Lloyd Binns Bequest, through Glasgow Natural History Society. This enabled them to construct this box, filled with sand and with 48 nest holes on the side facing the river, allowing sand martins to get access. This side of the structure can be opened, giving access to the tunnels and nests, so that young birds can be easily ringed (under licence) for migratory studies.
