Martes martes = Pine marten is one important predator of "our German
Squirrel" . All your different squirrels we do not have.
I found a pdf about: Grey squirrel management at GB as an unwanted invader:
And information about Marten Martes americana
In general predators of squirrels are:
Lynx, Martens crows, raven (nest), Coyotes, Bobcats, Foxes, Weasels,//
Minks, Wolf, Raccoons, Northern Goshawks,
Red-tailed Hawks, Cooper’s Hawks and occasionally Broad-winged Hawks,
Great Horned Owls, Barred Owls...
The *marten* (/Martes americana/) is a carnivorous, furbearing relative
of the mink
*Food habits:* Marten depend heavily on meadow voles and red-backed
voles or mice, which are their primary food source over much of Alaska.
Fluctuations in food availability often create corresponding variations
in marten populations. This condition is more pronounced in the less
optimum habitat of the marten. Probably the second most critical food
source is berries, especially blueberries, followed by small birds,
eggs, and vegetation. The marten is a voracious and opportunistic
feeder. Carrion such as the remains of wolf kills or salmon carcasses
are eaten in many areas. Wild marten are fond of sweets such as jam.
They will sometimes take treats from humans. *It has been reported that
red squirrels are a major food source for marten. This does not seem to
be the case in Alaska.* In fact, the two seem to get along quite well.
Marten commonly use red squirrel middens as resting places. Although
marten are suited for nocturnal foraging, they are occasionally seen
during the day just before stormy weather or immediately following a
In Germany our Pine marten likes our squirrels, but this may even differ
very much within Germany. Usually these predators are able to change
their food easily.
Your idea about their "fear about human population" is right, but since
many years in "overcrowded Germany" Pine martens are also more and more
close by with human settlements. Like e.g. also shy Foxes, Wild bores
occur in German cities... Usually in the past, they did not like to be
In any case The English Pine marten Martes martes is the one who hunts
squirrels in Germany.
But we have also a second smaller marten in Germany which is usually not
hunting our squirrels, but living usually only inside towns and villages
Farmers usually are loving this one, because it is killing mice and rats
much better than cats. *But also it likes farmer's chickens and ducks.
Anyhow farmers found simple methodes to close the chicken houses only at
night marten-proof. In any case Chicken-houses have to be always
fox-proof - all over the world! At daytime no risk. *
This marten has a very, very high tolerance to humans.
But the Pine marten is also becoming more tolerant to human settlements.
In general this is a very interesting subject, but also very complicated
because of the complex ecology.
Like e.g. in Australia almost all mistakes are made , which have been
possible to make...
Probably squirrel problems are solved with a combination of ecological
aspects and hunting and other methods.
I think only in small scale technical solutions will work well.
