Fence and Sign Posts a Source of Mortality for Raptors

Metal fence posts of a certain design have been shown to be a source of mortality for raptors, according to this RELEASE from the Fish and Wildlife Service:

The U.S. Fish and Wildlife Service has requested help raising awareness of the potential problems with certain sign and fence posts. The small holes drilled at the top of metal fence posts can trap raptor toes.

If these kinds of posts can't be avoided, installing several bolts to fill the top holes would be a simple and relatively cheap fix for the problem. It would be easy to include in project specifications.

This would also be a good project for Boy/Girl Scouts.

Thanks for your consideration of this issue, and please pass the word. See photos attached. Permission to use these photos to inform the public has been granted by Chris Dellith, Acting Assistant Field Supervisor, US Fish & Wildlife Service,
