Lead poisoning is still killing many birds, especially raptors who feed on carrion. When an animal is shot with lead ammunition and is later consumed by an eagle or other bird, the bird will also swallow the lead. That can either kill the bird or dramatically compromise it’s health through loss of balance, tremors or and impaired ability to fly. Such a bird will almost always end up as a dead bird. Sometimes, when found by humans, the bird can recover, but most of the time it’s too late.

According to a recent press release by the Peregrine Fund, Ravens in the Greater Yellowstone area show high lead levels during the hunting season. Hunters, after shooting elk and deer, left behind the gut piles which where consumed by the Ravens, of which many later had high levels of lead in their blood. Of course, the lead would not only affect Ravens, but all birds who feed on the gut piles like Golden Eagles or Bald Eagles. Grizzly Bears also are known to feed on the gut piles regularly.

Another problem are lead fishing weights which threaten loons and probably other birds with a similar biology than loons. See here for more information about this.

The best way to avoid future deaths of birds or other animals is to ban lead ammunition and fishing weights and replace it with something saver. Alternatives exist. It’s time that those unnecessary deaths of (often endangered) species come to an end.
