The House Martin survey over the next two years will collect more information on population size, breeding ecology and habitat preferences, so we can begin to tackle some key questions about this eagerly awaited summer visitor.
In 2015 the nationwide random square survey will involve volunteers visiting 2,000 – 3,000 ‘random’ (i.e. pre-selected) 1-km squares throughout the UK. By surveying random squares we can produce a robust population estimate to monitor future changes.
