All,
As has likely been read, insect abundance has precipitously declined over
the last many decades. As many birds are primarily dependent on insects
for at least part of their lives, it is not surprising that the loss of
insects cascades into a loss of the organisms that depends on them. We
could have all the suitable bird habitat in the world, but without the
appropriate food available at the right time, there would still be low bird
population numbers due to starvation.
In general, stopping new development, most pesticide use, and climate
change are the only ways to reduce this continued decline. That seems like
a tall order for culture/society, especially these days, and I haven't any
hope trends will change.
Doug Tallamy goes into the science behind this in more depth in his book
Bringing Nature Home, released some years ago. It's a fine read for both
the general public and researchers.
With regards,
Robert
