Dear
Journey North,
We
have had no sightings in the last week so either cranes
are still to come or they have moved on through. I suspect that
they moved through, taking advantage of good migration conditions. It
is snowing in Saskatoon today (May 8) so there won't be any birds
moving.
You
may have wondered where the birds stop at night in the final two
days of migration when they are north of the agricultural
areas. That is a good question! We only have a very limited
amount of information. We have a few records of birds stopping
along the edges of shallow lakes and on edges of rivers in northwestern
Saskatchewan and north eastern Alberta — but not much else.
Very few people live in those areas so there is a real lack of information.
Most of what we have is from some radio tracking that
was done in the early 1980's. We are hoping to get another radio
tracking project going in the next few years to help answer the
question of where the cranes land to rest.
From where I am based in Saskatoon,
SK, it's 1,000 KM to Fort Smith. That is where I go to be
near the the breeding grounds in
Wood Buffalo National Park. (For the cranes, 1,000 KM is
about a 3-day flight.) Soon I
will be starting aerial surveys to look for the nesting pairs.
I hope that we will have warm weather in June when the eggs begin
to hatch, so the chicks have the greatest possible
chance
of survival. Brian
