I've photographed the Sandhill Crane migration many
times. I produced some of my best images
ever today - March 18. It was my lucky day!
My day began at 4 AM in Bellevue Nebraska. I drove to Crane Meadows Nature Center - near
Grand Island and arrived at a viewing stand on the Platte River shortly before
sunrise. The cranes sleep in large
groups on islands in the river. I didn't
see nearly as many cranes there as I expected so I was concerned that I was
days early for the peak of the migration.
As the sun rose, thousands of cranes ascended into the air. Even so, the numbers were down compared to
previous years.
The cranes leave the river during the day and fly to fields
in over 1000 square miles of surrounding farmland. I've had the best luck traveling the 50 miles
between Grand Island and Kearney along dirt and gravel roads just south of the
river. The cranes feed in fairly large
groups in the fields. I use an 800mm
lens with a 1.4 extender for 1120mm of magnification for the majority of may
photographs.
Even with this
magnification, it is difficult to find cranes that will allow me to approach
close enough for the photographs I want to take. The four cranes in the photo above are leaning into the wind, ready to take off. Today was somewhat overcast. I have to shoot at f8 aperture wide open so
I'm limited in the amount of motion I can stop in the morning hours.
I take a tripod along with me but I seldom use it. Any crane brave enough to allow me to approach
in my car immediately takes off when I get out to use the tripod. If they remained, they would be to nervous to engage in dancing moves as shown in the photo above. I handhold my lens while resting it on my
open car window. It was windy today and
my car rocked with each gust.
I've learned that the first few hours of the morning are the
most productive. Later in the day, heat waves radiating from
the ground distort the distant cranes rendering most images useless. Thermal radiation is a problem on cold days
as well as warm. The photo above shows a few signs of this problem. Notice how each of the cranes and stems in the background hove multiplied into several nearly overlapping copies. The eye of the crane is still fairly sharp but much critical detail is already missing.
Most of the cranes feed in fields that were used for growing
corn or soybeans.
A super-telephoto lens
has extremely shallow depth of field.
Most of the time, out of focus areas of the photo have a soft pleasing
bokah.
Corn stubble is an
exception.
I find the bokeh in corn
fields to be very distracting so I try to avoid them. Notice how soft the background in in the photo above and how your eye is drawn directly to the eye of the crane.
There were several reasons that today was so successful for
crane photography.
The smaller number of
cranes meant a smaller number of crane watchers.
It was a week day as well so many people who
watch cranes were at work.
When I found
cranes to photograph, there was less traffic on the roads to scare them away.
It was a warmer day than normal for this time of March.
I expected to have more trouble with heat
wave distortion as a result.
However, it
was a very windy
day.
Apparently, the wind cancelled out most of
the heat distortion.
The wind helped out
in another way.
It provided additional lift
as the cranes danced so they danced higher and longer.
It was my lucky day. In addition my success was assisted by being
in the right place at the right time of year and picking the best backgrounds
at the right time of day with the right equipment and experience.
