Job Description:
In the spring of 2005 I headed out to the Midwest to work for
Louisiana
State University, School of Renewable Natural Resources as a
Wildlife Research Assistant on a project looking at declining numbers
of Lesser Scaup (
Aythya
affinis).
This job consisted of two separate parts. The
first, was
banding and color marking Lesser Scaup on Pool 19 (roughly where
Missouri, Iowa, and Illinois come together) of the Mississippi River,
and the second part was wetland surveys in the Upper Midwest.
I'm
not particularly fond of the Midwest, but it was very interesting (dare
I say fun) traveling around and experiencing the "culture" as well as
drinking cheap beer and playing pool in local bars.
Banding ducks at lock and dam # 19 (pool 19) on the Mississippi river
was the best part about this job. Pool 19 is a huge stop over
point for migratory waterfowl that follow the Mississippi flyway to the
prairie pothole region of the upper Midwest. Some days there
would
be hundreds of thousands of ducks on the river and you would look out
and just see specks of black all over with the majority of the birds
being Lesser Scaup. The local fish and wildlife biologists
told
us that it use to be an even more impressive sight before waterfowl
numbers started declining.
My day would start out waking up (relatively early) and going to check
traps and get a sex ratio survey on Lesser Scaup. To catch
Scaup
we used homemade funnel traps made of wire fencing with screening over
the top (see pictures) and baited them with corn. We had
roughly
12 traps placed from Keokuk, Iowa to Fort Madison, Iowa (roughly a 20
mile span on the Mississippi). After sufficient numbers of
birds
were caught in any give trap (upwards of 10, sometimes 30 or
more
in one trap) we would wade out in the river (in heavy duty Cabela's
neoprene waders) and scoop up the birds in a net, put them in cages,
and drive them back to Kibbe Field Station (where we were living) and
band them while drinking cheap beer and "shooting the shit".
It
was a good time had by all! After the ducks were banded, we
would
load the cages back in our trucks, drive them back to the river and
release them. Other than banding them, we would also weigh
them
and fit them with a colorful nasal saddle (made out of cattle ear tags
and fastened by threading heavy duty filament through the nares and
melting it via mini torch/lighter). The idea behind the nasal
saddles was to color code them based on body weight (two different
weight ranges), so that hopefully they would be re-sighted later on
their breeding grounds. Blood samples were also taken on some
of
the ducks by bleeding the brachial vein.
My time at Kibbe field station was fun, but eventually came to an end
and I headed out to North Dakota with my crew partner Tom.
Our
job from that point on was to perform wetland surveys throughout North
Dakota. Their were other crews working in Minnesota, South
Dakota, and northern Iowa as well. The surveys were pretty
straight forward. We had predetermined wetlands throughout
the
region that we would put out gill nets and minnow traps in and then
obtain dissolved oxygen content, salinity, conductivity, turbidity,
presence of invertebrates, emergent and submergent veg
characteristics, as well as overall landscape disturbances (i.e.
agriculture right up to waters edge vs. 5 meter buffer, etc.).
Essentially we collected every piece of information about the
wetland in order to determine its overall quality and potential use for
migrating waterfowl. The idea behind this project was that
wetland
quality has been diminishing over time due to agricultural impacts and
migrating waterfowl aren't getting the nutrients they need from these
wetlands, causing them to reach their breeding grounds in poorer
condition and ultimately fail nesting.
