Staff at RSPB Bempton were recently on hand to rescue a pair of binoculars after a visitor to the reserve dropped them over a viewing platform.
Jeff Hosier, from Bath, dropped his Swarkovski bins onto the cliff top beneath the wooden platform.
The seabird research team, Mike Babcock and Imogen Lloyd, responded to the SOS having heard of Mr Hosier’s dilemma.
They ‘roped up’ into safety harnesses before clambering down to retrieve the treasured possession.
To show his gratitude, Mr Hosier donated £200 to the nature reserve.
Site manager Ali Barratt said: “We’ve had to rescue more than a few seabirds in our time, but never a pair of binoculars. We went below and under for our visitor.”
