Being well away of the danger
(thanks, Credence Clearwater Revival) I went to Lodi for the Sandhill
Crane festival. They have had a festival for the Sandhill Crane for
the last 16 years. Their goal is to bring awareness to this large but
little known bird.
The Sandhill Crane is a large bird
with a few different subspecies that vary in size. The largest can
have wingspans up to about seven feet so these are big birds. However
they have had a mutation that limits them to the three forward facing
toes they have lost the rear facing toe that occurs on many of the
birds we see (check out a chicken foot). So they are incapable of
perching in tress. So their only way of protecting themselves at
night is to stand in shallow water, making it hard for predators to
approach.
Before the massive influx of gold
seekers and such back in the 1800s there were huge flocks of Sandhill
Cranes in California's Central Valley. It was pretty swampy in much
of it after all. But between the draining of the valley for farming
and market hunting for feathers the birds were almost wiped out.
While these birds mostly migrate outside of California, birds from
the Sacramento area fly up to Alaska and Siberia for breeding, they
need to have wintering grounds that supply them with food and safety.
And this means they need farmland with
grains after the harvest that aren't too far from shallow marshy
places for them to spend the night. And up near Sacramento they
actually have lands that are intentionally flooded to generate
winter wetlands for the cranes. But there is still a problem with
habitat “destruction” for the cranes. They can't use vineyards
for their winter food supply and the area around Lodi is known for
its wine so there are numerous vineyards and it is growing.
However there are a couple (so far) of
the vineyards that are trying to develop in ways that will provide
some benefit for the cranes. For example trying to maintain a
wildlife friendly area as part of the vineyard. And the festival
itself has the goal of educating the people of the area o the unique
winter inhabitant they have.
Now as part of the festival there was
a woman who had created a wonderful little documentary about the
process of raising a young Sandhill Crane up in the area of Homer
Alaska where the Sacramento area birds breed. There were also people
there that work on the research, which includes tracking down the
different areas that the different groups of birds utilize over the
course of the year.
Now if you want to see Sandhill Cranes
you can drive up to the Lodi area and head out to many viewing areas
they have set up. Or you can drive up to the Pixley area, which is
probably less than two hours away and go to the Pixley National
Wildlife Refuge. They also get large numbers of the Sandhill Cranes
over the winter, up to 6000 according to the refuge website. There's
plenty of other bird life out there, so don't go just for the
Sandhill Cranes.
But if you head out there a little
before sunset, you might catch the “fly in” where the birds that
have been out foraging all day come back to the marsh for the night.
It is quite an impressive sight. Thousands of birds coming down
making a loud racket. Amazing. And worth a trip.
