• The risk of sparrowhawk predation at individual lofts was related to the<br />

surrounding habitat. The group of lofts with ‘substantiated’ and ‘probable’ losses<br />

to sparrowhawks were surrounded by a significantly greater percentage cover of<br />

woodland than the group of lofts with only ‘possible’ losses and no losses to<br />

sparrowhawks.<br />

• Of the 32 lofts studied, 13 used some form of avian deterrent, including 8 of the<br />

11 lofts with substantiated or probable losses to sparrowhawks. Deterrents used<br />

were replica owls, terror-eye balloons and reflective discs. The strategy of<br />

deterrent deployment at individual lofts, however, is not known.<br />

• There were a further seven reported incidences in which losses from the loft area<br />

were attributed to raptors other than sparrowhawks - six peregrine and one<br />

goshawk. Five of the six reported peregrine incidents took place in the<br />

Stirling/Dunbartonshire region. Stirling is a region in which a number of<br />

peregrine eyries are located relatively near to lofts.<br />

1.4 LOSSES TO PEREGRINES<br />

• A total of sixteen releases (thirteen races and three training flights) were attended<br />

at a range of locations to check for raptor activity. The only evidence of raptor<br />

activity was one peregrine attack in the vicinity of pigeons training in the Largs<br />

area. No scattering of the flock was noted due to the attack, although one pigeon<br />

did not return to the loft until the following day.<br />

• A total of 59 eyries in eight regions were searched for racing pigeon rings.<br />

Overall 17% of all inland eyries in these eight regions were searched, representing<br />

c.2% (NW England) to 66% (Dumfries & Galloway) of all inland eyries in<br />

individual regions.<br />

• A total of 1,213 pigeon rings were recovered during the eyrie searches, of which<br />

720 belonged to the SHU or its predecessors. A total of 308 rings of recent origin<br />

over six years (i.e. 1997-2002) belonged to Scottish pigeon fanciers. Altogether<br />

74% of these provided some information on the history of the bird in question and<br />

91% of these provided full information on where and when the pigeon was last<br />

released. A total of 117 pigeons were reported by their owners as having been last<br />

released in 2002 and therefore taken that year by peregrines. This gives a mean of<br />

1.98 Scottish racing pigeons per eyrie searched. Correction factors were used to<br />

take into account the fact that some owners could not provide the required<br />

information and that a proportion of rings would not have been recovered at many<br />

sites (based on re-searches of six sites). By applying these correction factors, a<br />

mean of 4.76 Scottish racing pigeons killed per eyrie searched is obtained. This<br />

suggests that the number of Scottish racing pigeons taken by peregrines is<br />

approximately 4,100 (1.2% of the Scottish population). As the work progressed it<br />

became clear that this method has limitations. As such, it provides only a<br />

minimum figure of pigeons killed and does not accurately reflect the actual<br />

number predated.<br />

• Peregrine nesting sites and the SHU Federations of the pigeon rings recovered at<br />

each eyrie were allocated to one of three regional categories (East, West, and<br />

Central). This was done separately for old birds (95 rings) and young birds (58<br />
