Steve Shipley, from Driffield, photographed the peregrine falcon on the North Yorkshire coast earlier this month.
He does not wish to disclose the location where he saw the bird, as peregrines are a protected species and are often targeted for persecution.
The raptor was carrying a PPE-style disposable face mask that had been discarded as litter.
Face mask wearers have been warned to safely dispose of unwanted PPE in bins and not to leave them anywhere where another person may come into contact with the item.
