What I wonder is that with various long term reports of many species
showing declining trends across many species/habitat groups, and major
losses of bird numbers since the 1970s etc., why are we surprised that
there are often poor migratory showings? Shouldn't we expect fewer and
fewer migrants, even now at what ought to be the peak of a typical
migration season? If the reported population declines are as great as those
reported, surely we will have fewer birds. I wonder, as often it seems we
think maybe they took another route, or maybe they are just late, or? Are
the long term trends that are highlighted in reports of the state of birds
wrong?
Just wondering,
