I am the lady who wrote the Homer City ordinance that prohibited the feeding of bald eagles, crows, gulls and scavenging birds. The law was passed in 2006. It has been very successful.  This is due to the public awareness campaign that I created with the help of local citizens some who were wildlife biologists on the unintended consequences of feeding nuisance birds, so I made the American Bald Eagle a "nuisance" bird, first time in history I am sure.  As a nurse I worked with the State DEC on the health hazard that such feedings create. I got the Homer Police on board to actively enforce the law and they did just that.  The signs are up all over Homer and I am proud of that. They city is cleaner but the birds still get in the fish wastes at the cleaning station but there is a plan to cover the main one as the others stations have been covered. The change was rapid and went well.  I travel the nation speaking of the unintended consequences of feeding urban wildlife.
