Black vultures in line of fire
Black vultures, southern cousins to our turkey vultures, are moving north into Missouri, Tennessee and Kentucky in growing numbers, putting themselves on a hit list in the process.
Although protected by law like other U.S. birds, black vultures now can be shot in some circumstances because of attacks on baby farm animals, according to St. Louis Public Radio. Calves and lambs are being killed shortly after birth by the birds, usually scavengers. State departments of natural resources are allowing the birds to be shot to lessen the problem.
A spokesperson for the Missouri Farm Bureau called the vultures "aggressive, nasty birds."
Conservationists say climate and habitat change are causing vulture numbers to rise.
Black vultures are extremely rare here. There are no reports of similar behavior by turkey vultures, migrants soon to return to Minnesota.
