Official
figures state, based on 1991 figures that there are nearly 1300
breeding pairs of peregrines in the UK and at least 2000 immatures.
As peregrines produce 1-4 young per year per pair, (on average 2
young per pair) this is a possible 2600 young peregrines fledged per
year. With the various raptor groups reporting no significant
increase this means that the RSPB etc are saying that a possible
2600 peregrines die per year.
The
total of sparrowhawks is quoted as 34,000 pairs in the UK with
another possible 68,000 young fledged. Still there is no significant
increase admitted to and in fact the various groups are now claiming
a decline. The implication here is that the 68,000 born all die.
Taking
just these two species of raptors pro raptor groups such as the RSPB
are claiming a yearly loss of a possible 70,600 raptors. Where are
they? How many are handed in to or reported to the police? (The RSPB
and police are campaigning to have the deaths of raptors reported to
them.) Taking into account that according to raptor reports,
including the latest DETR Raptor Working Group report, raptor
numbers are not “soaring” and some are declining, where are the
carcasses of these dead birds? We believe the birds are out there
not being counted, because no one can count immatures and many nests
are not found.
The
RSPB maintain that raptor persecution is affecting the population
increase of raptors. Yet the accepted figures on raptor numbers over
the last 20 years have shown a marked increase in most species, and
gamekeepers’ experience leads them to believe that these figures
are below the actual numbers. RSPB figures for Scottish species
between 1970 and 1998 show an increase of 162% in Sparrowhawks and
224% in buzzards. As raptor numbers are actually increasing, even by
their own figures, it has to call into doubt the RSPB’s statement
that the raptors found dead are “only the tip of the iceberg.”
The reality of the figures proves the fallacy of their dramatic,
headline grabbing statements.
Reports
from gamekeepers across the country as well as others suggest that
raptor numbers as claimed by the RSPB and raptor groups are grossly
underestimated and well under the actual numbers in the countryside.
When quoting any raptor population it is only the known nesting
pairs that are quoted. There is no hint of single or immatures in
the numbers mentioned as numbers are always quoted in known nesting
pairs. This gives a false impression of possible raptor predation.
It is worth noting that raptors do not die just because they do not
have a mate.
The
RSPB continually report that bad farming practices are responsible
for small bird declines and undoubtedly some of the practices
farmers were encouraged to introduce damaged the native flora and
fauna. But that is not the entire story. Pesticides are not used on
moorland and very few moors are overgrazed by sheep. Also, here we
have some quotes from the Historical Atlas of Breeding Birds in
Britain and Ireland 1875 - 1900 by Simon Holloway (1996) (these same
people are quoted by the RSPB in their references), which give a
different angle on the situation:
“Tree
sparrow populations increased when sparrowhawk numbers were
decreasing in 1946 - 65 and decreased during the sparrowhawk
recovery in 1966 - 92 (Smith Summers in litt)”
“House
sparrow: Tawny owls, sparrowhawks, and domestic cats are all
significant predators of the house sparrow and their increase in
suburban areas may be sufficient to reduce the house sparrow
populations in these habitats (Gibbon et al 1993)”
“Bullfinch:
(Newton 1967) suggested that lower numbers of sparrowhawks were
allowing the bullfinch to feed further from cover making much more
food availabl e.
The bullfinches’ increase of the 50s and 60s has reversed and the
population is in decline perhaps associated with the recovery of the
sparrowhawk. (Newton 1993)”
Another
quote from Newton (93/94) in the Hawk and Owl Trust Report (1999)
states that most raptors are considered close to the maximum
densities that their habitat can support.
It
is worth noting that the RSPB lay great store in the findings of
Newton et al. when quoting figures that help to promote their cause,
but fail to mention some of these other findings.
It
seems logical to suggest that if sparrow hawks could effect the
numbers of common birds like the sparrow and bullfinch they must be
having a direct effect on less numerous species such as the skylark,
bunting and thrush.
The
RSPB in its haste to blame farmers for songbird decline omits to
tell us that species such as the redpoll “fluctuate markedly in
abundance both from year to year and as the present study reveals,
in a longer term cycle, over periods of decades.” (I Newton in
Litt) or that other species such as flycatchers, whitethroats, sedge
warblers and sand martins suffered large losses of numbers due to
rain failure in the Sahel region of West Africa used in passage from
wintering grounds in Southern Africa. Further information in this
book gives indications that large fluctuations have occurred because
of climatic changes at home and abroad for many other species. The
RSPB fail to explain this to the public. Instead they choose to
scaremonger by blaming all bird declines on farming practices,
ignoring varying reasons for songbird declines.
Although
some of the above would appear to have little to do with game
keeping it hopefully illustrates how selective the RSPB are in
providing information on bird numbers.
Peregrine
falcons are becoming a major threat on some grouse moors. These
birds during the winter and spring months will kill at least one
grouse every two days. As this is the only prey available until the
return of the waders and even when the waders return grouse will
continue to be killed. Every loss of an adult breeding grouse is a
loss of a potential brood and hence to the potential surplus
required to promote a good shooting season. Birds killed in the
winter are the breeding stock for the next year. These losses can
affect as much as 40% of the breeding stock.
Sparrowhawks
attack partridge all year round, keeping stocks low. (The wild grey
partridge is an endangered species.) During the release of pheasant
poults the sparrowhawk is particularly troublesome, killing every
day and terrorising the poults, which then do not feed. This adds
more stress and usually leads to stress related diseases, which can
be fatal.

Goshawks
are a particularly aggressive raptor that even attacks other
raptors, and is also reported to be killing squirrels. In areas
where red squirrels (an endangered species) have their last
stronghold this bird is a threat to their survival. Goshawks kill
adult game birds as well as poults, and also kill grouse. After a
visit from a goshawk at a release pen the escapee poults are
reluctant to stay in the area. This leads to starvation and
predation by other species of predators in the thick summer
vegetation.
The
buzzard is now the main predator of pheasants and partridge. No up
to date numbers are given for the buzzard population but we estimate
that there is one pair of buzzards for every 100 acres of woodland
in Scotland. This makes it the most numerous raptor in Scotland.
This raptor is so numerous that it can be seen in groups of 6 - 10
birds. Yet the RSPB etc.(based on 1991 figures) have placed the
number at only 17,000 in the whole of the UK and continually imply
that this bird is rare and endangered. Buzzards according to the
RSPB are carrion eaters and seldom kill their prey. This
unfortunately is not the case. Buzzards regularly kill adult
pheasants and partridge and those that live in the woods fringing
heather moors will take grouse should the opportunity occur. The
main prey of buzzards during the nesting period is ground nesting
bird chicks and young rabbits. They also take young songbirds. They
also find the released pheasant and partridge poults easy prey. Once
the raptor has locked on to an area where it can predate pheasant or
partridge chicks it will continue to visit. Not only will the
killing do damage to the stock but the stress factor will be
increased resulting from food deprivation caused by straying.
It
is estimated that out of 1,000 lowland shoots each shoot is losing
an average 150 poults to direct raptor predation in and around
release pens. At £20 per bird that is a possible loss of revenue of
£3,000,000 income to shooting estates across Scotland. This would
eventually be ploughed back into the local communities. The direct
damage done to grouse stocks can only be guessed, but a similar
figure of £3,000,000 must be a close estimate. It is unlikely that
this scale of financial burden is carried by any other Scottish
industry without recourse to compensation. Gameshooting is not
subsidised in any way and must make its own money to sustain
habitat. Therefore it is important that budgets are met. These
budgets are becoming increasingly difficult to meet with raptor
predation on the increase.
With
raptor populations in excess of 100,000 and rising in Scotland
alone, raptor predation on all prey species can only get worse. A
solution to this problem must be found now. |
