When I got off the
plane at the airport we walked out the back ramp of the 727 stretch.
As I walked out the door the heat hit like a fist. My first thought
was “Jet exhaust” but no, it was just the ambient temperature.
The ship was docked at a commercial pier. Running parallel to the
dock were 6 sets of railroad tracks used to bring cargo to and from
the ships. In the last few days they had been loading a lot of grain.
So sloppy were their methods that all the tracks were filled with
spillage. After a few days of short showers and lots of sun the grain
began to rot and the flies came out to feed and breed.
We were going
crazy on deck trying to work. We were soaked with sweat and covered
with flies. I couldn’t wait to get away from there. We had fly
paper hanging all over the place and it was amazing how quickly one
of them would “fill up”. Once we were at sea we could start to
deal with the problem but first we had to get away from that dock.
When we did leave we brought a complete food chain with us. There
were an uncountable number of flies being eaten by some 50 chickadees
that were in turn being eaten by the two sparrow hawks that joined us.
After a few days
we noticed the fly population was dropping noticeably. Also there
were little piles of beaks and feet with a few yellow feathers.
Evidence that the sparrow hawks were on the job. The aerial
acrobatics were amazing. The hawks chased the chickadees with
blinding speed and maneuvering. We also found a few of the chickadees
stuck to the hanging fly paper from trying to get an easy meal. These
went over the side as you would leave most of the bird on the paper
if you tried to pull it off. Besides, there is nothing nastier that a
well used piece of fly paper. About a week later the sparrow hawks
disappeared having dispatched all their prey on board.
I’ll be back to
Mexico soon and I can promise you I have several rolls of fly paper
stashed.
