In our new series which we have named after birds there are 15 caches to be found. Pen and tweezers may be required.
These are our first attempt at hiding caches.
The series covers a walk of roughly 2.5 miles on country lanes and public footpaths, with a stretch alongside a fairly busy road.
The males live up to their name but, confusingly, females are brown often with spots and streaks on their breasts. The bright orange-yellow beak and eye-ring make adult male blackbirds one of the most striking garden birds. One of the most common UK birds, its mellow song is also a favourite.
