11.10 a.m., 49ºF, 9ºC, Wakefield Cathedral; A flock of town pigeons circles and chacking jackdaws return to the belfry ia the louvred shutters, unperturbed by the presence of a peregrine preening on a crocket, halfway up the north-east side of the spire.
It’s wonderful to be able to sit on a bench in the precinct and sketch a peregrine. 
When I started birdwatching in the late 1960s and early 1970s, the first peregrines that I saw were in a remote glen in Scotland and on the far south-west corner of Wales, on the Pembrokeshire coast.
Over much of the country they had been wiped out through partly through persecution but probably more because of pesticide residues in their prey species, which caused a thinning of the shells of their eggs.
