Use copper strips to exclude snails from nests Bird Conservation

A small before-and-after study in a forest in Black River Gorges National Park, Mauritius (Tatayah et al. 2007) found that African giant land snails Achatina spp. did not enter seven nest holes used by echo parakeets Psittacula eques between the 2004/5 breeding season and 2007 following the installation of a 50 mm wide strip of copper around the trunk of each occupied tree. Before copper strip installation, four chicks were found dead in two nest holes between 2003 and 2004 due to asphyxiation by snail slime on the snail’s foot.
