Dear All,
There are signs that species on the Australia-East Asia flyway are
not the only ones experiencing drastic reductions in numbers. A
report from the 'Independent" in the indicate that similar crashes in
numbers of species using the Europe-Asia flyway are occurring, see
http://www.independent.co.uk/environment/nature/the-great-migration-
crisis-812640.html
I do not know if similar reductions in numbers are occurring in
species using the North America-Neotropics flyway are happening, but
one would imagine that it may be so. Can anyone on the list add any
information on this flyway?
These reductions in numbers on the Europe-Africa flyway are very
worrying, not only for birders. So many of the species are
insectivores and are important in controlling insect pests in food
crops. Reduction of yields in Africa's food crops would lead to even
greater risks of famines on the continent, not a pleasant thought.
Increases in pests in Europe's food crops would lead to higher
production costs and therefore higher food prices in the third world.
A drop in bird numbers certainly has the potential for disaster if
you look at all the implications.
