As spring arrives Sand Martins are making their way from sub Saharan Africa to the UK in their annual migratory journey. Thanks to efforts beginning last year in the 2013 Sand Martin Awareness campaign, this year they will be returning to CEMEX quarry sites that have been specially prepared for their arrival.
In 2013 approximately 200 birds made the journey to the Berkswell quarry where they found ideal nesting conditions. After their long migration, Sand Martins love finding steep-faced sandy banks where they can dig nest holes, sometimes up to 1m deep, which help protect them from predators. The quarries are also home to many insects which provide the necessary nourishment the Sand Martins look forward to after their tiring trip.
This year, CEMEX is striving to build on last year’s campaign and provide an even more hospitable habitat for their returning guests. For 2014, the plan is for all quarries to have a specially prepared sand bank sensitively located such that day to day operations won’t disturb them.
