Hmmn. Eating an egg or chick is 100% destructive to it, true, but how many
birds' eggs and chicks does the average squirrel consume each year,

IME, a large number. (So do hedgehogs, BTW)

? and,
more important, what effect do squirrels have on bird breeding success?

IME, quite a lot. A whole clutch goes. The chances are, the bird will
lay another clutch in the same nest, and the sqrl will return.

Dr
Mark Avery, Director of Conservation for the RSPB wrote in a letter to the
Telegraph on 22nd October, 2007, "Grey squirrels are not found in most
other
parts of Europe, yet woodland bird population is also dropping on the
continent. ... Poor woodland management, climate change and factors
affecting migrating birds are far more significant."

And grey sqrls are the icing on the cake.

Wise words, IMO, and I
don't believe we should rush to judgement to scapegoat squirrels, magpies
and sparrowhawks for observed declines in bird populations.

Well, as someone who spends a lot of time in the company of gamekeepers,
and on big estates, I can assure you that Sqrls and magpies (jays and
crows too) have a very significant effect on small bird populations
round here.

Sparrowhawks to a lesser extent, but their numbers are rising so fast
that even RSPB people are getting a bit worried about them, especially
where endangered species are concerned.

In addition to changes in the climate and in agricultural practices at home
and abroad, there are plenty of gardeners who have been doing their bit to
destroy birds' habitats, by removing nesting sites (trees, shrubs, holes
under eaves, etc), food stuffs (weeds and seeds etc) and paving over or
decking land which used to produce invertebrate food for birds. Wouldn't it
be ironic if such people were to start killing squirrels and magpies
because
they don't notice so many birds about as there used to be?

And of course, those who haven't, because the sqrls are digging-up their
bulbs and veg, and raiding some crops, as well as eating the food put
out for the fast-disappearing birds.

Interesting. Are there some estates where they exterminate the squirrels,
magpies etc., and some where they don't, and where surveys of the
pre-breeding populations of the various resident songbird populations show a
significant variance?


Sparrowhawks to a lesser extent, but their numbers are rising so fast
that even RSPB people are getting a bit worried about them, especially

It's only natural for people concerned with the survival of an endangered
species to get hyperprotective about the risks the population faces. But
sparrowhawks are unlikely to specialise on a particular species. Indeed,
they take whatever is available and easy to catch. So if there are plenty of
'unendangered' fledglings about, they'll probably take more of them than the
endangered ones.

Squirrels are clever, but not clever enough to realise that food left out in
people's gardens isn't intended for them :-)

Yes, and no idea.

Sparrowhawks will take pretty nearly anything that flies and isn't much
bigger than a pheasant, and raptors tend not to care wheter dinner is an
endangered species or not.

Why do they run away when caught at it, then? Colon dash close parentheses
