Chris,
We have noted a continuous decrease in numbers banded, seen and heard
over the last 33 years. What species do come in and sing do so for a
shorter and shorter period. We believe it is a factor of ever lower
number of migrants with the concomitant decrease in territorial marking
and defense.
When I read Silent Spring in the very early 60s I was sure the world
would wake up. Sadly it has not and this has truly been the most Silent
Spring in our time here. First year here without a Wood Thrush as but
one example.
Imagine, Bayer is still making and marketing DDT and on top of that all
the new "better living through chemistry" junk that have become bird
killing weapons. Human overpopulation is the root cause I believe as it
drives all the rest.
