This is all the information that I have been able to gather on the subject, but it is enough to, at least, suggest the church was, at one time, haunted by the phantom of a bird, but whether the earth-bound soul of a murderer taking that guise, or the spirit of an actual dead bird, it is impossible to say.
The Ghost of an Evil Bird
Henry Spicer, in his Strange Things Amongst Us, tells the story of a Captain Morgan, an honourable and vivacious gentleman, who, arriving in London in 18—, puts up for the night in a large, old-fashioned hotel. The room in which he slept was full of heavy, antique furniture, reminiscent of the days of King George I, one of the worst periods in modern English history for crime. Despite, however, his grimly suggestive surroundings, Captain Morgan quickly got into bed and was soon asleep. He was abruptly awakened by the sound of flapping, and, on looking up, he saw a huge black bird with outstretched wings and fiery red eyes perched on the rail at the foot of the four-poster bed.
The creature flew at him and endeavoured to peck his eyes. Captain Morgan resisted, and after a desperate struggle succeeded in driving it to a sofa in the corner of the room, where it settled down and regarded him with great fear in its eyes. Determined to destroy it, he flung himself on the top of it, when, to his surprise and terror, it immediately crumbled into nothingness. He left the house early next morning, convinced that what he had seen was a ghost, but Mr. Spicer offers no explanation as to how one should classify the phenomenon.
It may have been the earth-bound spirit of the criminal or viciously inclined person who had once lived there, or it may have been the phantom of an actual bird. Either alternative is feasible.
I have heard there is an old house near Poole, in Dorset, and another in Essex, which were formerly haunted by spectral birds, and that as late as 1860 the phantasm of a bird, many times the size of a raven, was so frequently seen by the inmates of a house in Dean Street, Soho, that they eventually grew quite accustomed to it. But bird hauntings are not confined to houses, and are far more often to be met with out of doors; indeed there are very few woods, and moors, and commons that are not subjected to them. I have constantly seen the spirits of all manner of birds in the parks in Dublin and London. Greenwich Park, in particular, is full of them.
Addendum to Birds and the Unknown
Though their unlovely aspect and solitary mode of life may in some measure account for the prejudice and suspicion with which the owl, crow, raven, and one or two other birds have always been regarded, there are undoubtedly other and more subtle reasons for their unpopularity.
The ancients without exception credited these birds with psychic properties.
“Ignarres bubo dirum mortalibus omen,” said Ovid; whilst speaking of the fatal prognostications of the crow Virgil wrote:
