Why feed organic?
Although modern
farming methods produce cheap and plentiful food, they also have a
big impact on the variety of wildlife seen in the countryside. This
in turn can affect the number of bird species which visit our gardens.
When research has
been carried out to compare organic and conventional farming methods
it has been found that for most bird species, the numbers found were
greater on the organic farms.
Over the last 25
years the use of insecticides and pesticides has increased, and recent
developments in herbicide resistant crops has added to the pressure
on wildlife and habitats.
Feeding Burns Organic
Food makes sense :
- The British
Trust for Ornithology has shown that over the past 25 years, numbers
of several farmland bird species have declined. This period of
time has also seen major changes in farm management practice.
- The populations
of 22 of Britain's most common birds have dropped by more than
50% in 25 years, and with some species the decline would seem to
be accelerating. The once common sight of skylarks and starlings
is becoming rarer as farming and forestry methods have reduced
winter food supplies needed for breeding and survival.
- Powerful chemical
pesticides and herbicides leave residues on the grain which birds
eat. Having a very high metabolic rate, birds eat a far greater
quantity of food for their body weight than we do, with a result
that these chemical residues build up in their system.
- Not all poisonings
result in immediate death. A poisoned bird may lose weight, increasing
its chances of dying from other stresses, such as bad weather.
It may sing less and fail to attract a mate or defend a territory.
It may raise smaller broods or provide less food for its chicks.
