We feel, and experts support us, that these goals go hand-in-hand, and that crows can be managed without harming them. Our results in the winters of 2007/2008 and 2008/2009 provided strong evidence that non-lethal management IS the way to go. We'll be continuing to use these methods each year.
Based on analysis of 2007/2008 data -- gathered by Penn State scientists who tracked radio-collared crows and who observed the birds and literally engaged in "counting crows" -- our non-lethal management, using pyrotechnics and effigies, worked in several ways:
- Large roosts were broken up into smaller groups of birds and moved out of the city and suburban areas
- Once the roosts were broken up and moved, they didn't stay long in the next spots they chose. Minor management, in the form of a few evenings of pyrotechnics, moved them again when they chose spots that caused problems for people. A very small number of effigies, placed by township & city personnel, kept crows out of selected areas, as a sort of "follow-up" reminder to the crows that certain areas are off-limits.
This coming year (the winter of 2009/2010) we'll be using the same tools and methods. We start in November, as crows are turning up after the warmer weather has ended in New York, New England, and Canada, and will continue our efforts, as needed, into January. The management will be most intense in December and early January, when we anticipate the highest numbers of crows to have arrived and be looking for places to roost.
We will also continue to utilize the concept of tolerance zones where crows are not accepted at all ("Zero Tolerance" zones), zones where some crows would be acceptable ("Moderate Tolerance" zones), and zones where crows are completely OK ("Full Tolerance" zones). We'll be making the Zero Tolerance zones inhospitable (with pyrotechnics) from the start, with the intention of showing the crows where they'll encounter the least amount of harassment from humans -- in places where we leave them alone (in Moderate and Full Tolerance zones).
Effigies, used VERY conservatively in 2007/2008 and again in 2008/2009, worked very well. A single effigy can keep a relatively large area clear, even after the effigy itself has been destroyed by wind and rain.
We'll continue to use the effigies, sparingly, in Zero Tolerance Zones. It's important that people NOT put up their own effigies or move any that the Coalition places -- officials will be tracking each effigy and its impact on the crows, and having too many or having them appear in places where we don't want to scare the crows can reduce the effectiveness of our efforts. If you have questions or want to have an effigy placed on your property, please call our hotline at 717-413-2545.
While we'll always have crows migrating through Lancaster (the county has been in their internal itinerary for centuries), and probably large numbers of them (usually about 30,000), we can and will keep moving them out of undesirable spots and working to fine-tune the non-lethal, effective ways to prevent their causing any damage to property or making a mess with their droppings in public areas.
There ARE some places where they don't bother anyone, where people are either unaware of them or are able to enjoy them, and it's in those places where we'll leave them alone so they learn to stay where no harassment occurs.
You could be breaking the law (it's illegal to kill them), you could be
causing harm to other animals (poison you put out yourself will kill other
animals, too, which is also illegal), and you risk counter-acting the
official management methods being used. If you think you've got a problem
with crows (and simply SEEING CROWS is NOT necessarily a problem!), call
