Graham Williams coordinated the Peregrine Survey within Montgomeryshire this year and here's his summary of the findings -
Good coverage was achieved in the county for the 2014 BTO Peregrine Survey, many thanks to the observers who made this possible.
The results showed that there were 15 pairs in 2014, of which 6 were successful, raising a total of 13 young. One further nest which was probably successful was six feet on the wrong side of the county boundary!
These figures illustrate the changing fortunes of this iconic species. In the ten years before the Second World War Derek Ratcliffe, doyen of all Peregrine enthusiasts, computed that the average population in Montgomeryshire was seven pairs. In the years 1962 to 1964, at the height of the population crash caused by the effects of organochlorine insecticides, he knew of only one breeding pair in the county which failed twice and reared young once.
By the survey of 1981 the population had recovered to six pairs and by 1991 reached an all time high of 23 pairs (of which 13 successful pairs reared 22 young). In 2002 there was a slight reduction to 20 pairs, of which 10 were successful, rearing 19 young.
The 2014 results show that the decline continues and that several formerly occupied eyries are now deserted. Likewise breeding success was limited, partly at least probably due to heavy rain at a critical stage of the breeding cycle.
Whilst there is still a healthy population in the remote uplands (and elsewhere in Wales the coast) there is a recent well documented trend for Peregrines to become city dwellers, attracted by the abundance of feral pigeons and other prey.
