Crows and Cormorants

Hello Ontbirders
Yesterday morning Alan Smith, Brian Ahara and I birded a number of our usual
haunts in Niagara.  We covered both piers at Port Weller, McNab Road,
Avondale SP, most of the roads leading to the 5th and 8th pond, around St.
David's SP, and back up through Virgil.  In the entire morning we saw only
ONE single crow.  Early each morning along Hwy 406 as I drive north to St.
Catharines, I am accustomed to seeing a large number of crows as they head
to their feeding areas from their overnight roost.  This morning I did NOT
see a single crow.  Clearly the West Nile virus has decimated the crow
population in this part of Regional Niagara, and likely all over Niagara.

We walked the half mile north from the Coast Guard Station on the west pier
of the Welland Canal at Port Weller to the tip.  No one will ever believe
the cormorant problem.  We conservatively estimated in excess of 300
Double-crested Cormorants have taken over the 8 or 10 largest trees.
Perhaps 90% of the birds were immatures, which begs one to wonder if their
nests were in Niagara.  They clearly roost in these trees at night, and
as we walked up the path, we flushed more than 200 birds that were at rest
on the larger branches.  On the outer edge of one tree I counted 56 birds.
All of the smaller trees and the brush below these large trees were covered
in white cormorant excrement.  The path we walked along was also totally
white from their droppings.  A large circle of white was evident below each
tree.  Most of all, the smell was nearly unbearable.

While the Coast Guard people are very unhappy about these visitors, the
birds may well nest there as early as next year.  When they asked how they
could get rid of them, I suggested that in all likelihood the birds will
migrate south over the next few weeks.  They can hardly wait for that to
happen.  Anyone birding on the east pier will easily be able to see this
cormorant activity from there.

Hi All,

Maggie Smiley tells me the crows have gone down in number substantially in
NOTL. I just wondered if anyone else has noticed a dearth of crows. (There
are many terms describing numbers of crows but not sure what to call
missing crows.)
