Blake, all;
   the old Bowater Mersey warning signs are still at the Sandy Lake =
sawdust pile, but they haven=E2=80=99t been kept up for years. Most are =
on the ground or badly askew. And the messages about =E2=80=98special =
ecological site=E2=80=99 or something similar are badly bleached out and =
only partially legible. They should be removed.
   I remember regularly seeing bank swallow colonies in eroding clay =
banks of local rivers such as the Musquodoboit or the Stewiacke. But, =
now that I think of it, it=E2=80=99s been many years since I=E2=80=99ve =
seen an active local bank swallow colony...

The site was reasonably well-protected by Bowater, with large boulders =
in place that made it awkward for ATV access, and warning signs (since =
gone, though the boulders remain). =20

Despite these precautions the colony declined in size, concurrent with =
the decline in swallows across the province.  I do not believe the ATVs =
were much to blame.  I saw 8 birds at the colony in 2005, and a single =
bird in 2006.  None since, though I saw a single bird over Sandy Lake in =
2008.

The piles of sawdust have been used through the years by one or two pair =
of kingfishers as well, though I haven't checked recently.

Cheers, =20
