This is a very lethal situation and has been well documented and known about for many years. To have an animal dying from lead is one of the worse things I have ever seen. I wouldn't wish it on my worst enemy. Recently, the endangered California Condors living on the Utah/Arizona boarder have been dying at an alarming rate due to lead ingestion. This has always been a problem for the Condors there and other scavengers as well, such as Golden Eagles. Finally, this is getting some attention from the main stream media. I've attached a story, from here in Utah. Please educate yourself and those around you.
