More than 100 nestboxes have been ‘uncorked’ as Peak District rangers prepare for the return of a rare migrant bird.
Over 30 pairs of rare pied flycatchers arrive in the ancient oak woodlands at Padley Gorge, near Sheffield, from West Africa every spring.
To make sure there are enough nest boxes for the red-listed birds National Trust rangers stopper the entrance holes to 100 boxes in March to prevent blue tits and great tits from using the homes. Around 20 rangers and volunteers return in April to remove the bungs.
