Today I drove a couple of hours to visit a site in hopes of some unique bird photography. Neither the weather nor the birds cooperated very well. The location was near a popular boat launch and fishing area. It also turned out to be a favorite hang out for black vultures which are not what I was there to shoot.
For unknown reasons(duh) the vulture population in the USA has grown rapidly over the past thirty years. Both their feces, urine, and defensive vomit are highly acidic. Unfortunately they have a propensity to roost in large numbers on man made structures such as large steel power poles which don't react well to being covered in acidic excrement. In addition to the "acid rain" issue, they have very sharp and strong beaks and talons and (for unknown reasons) tend to land on parked automobiles and destroy the paint job, windshield wipers, and rubber window seals. In general as their numbers grown they are becoming very destructive.
Since they are migratory birds they are regulated in the USA by federal law which strictly prohibits killing them, disturbing their nests, etc. Federal wildlife officials tend to be less than sympathetic when wildlife has negative impacts on people. But in their infinite wisdom they did come up with a solution to the vulture problems. After much study at who knows what expense, they came up with an "effigy" program. Basically "studies have shown" that if you display a fake dead vulture, the others upon seeing it flee the area never to return. They go crap on someone else's stuff.
The area that I visited has implemented an "effigy" program to disperse the vultures. Below is a photo of a sign that is posted at the base of a structure resembling an old fashioned gallows from which one of the effigies was hanging. To save your eyes the sign reads:
"Duke energy is currently working with the US Department of Agriculture to disperse black vultures...Vulture effigies provided by the USDA are being used in an attempt to disperse roosts...
Here's a shot of the effigy. It looks like the remains of a dead bird hung upside down.
And the results of the studies paid for by taxpayers?
I wish the IRS was as effective...
