Collision with watercraft is a common cause of loon deaths, and so is lead poisoning.

The following tips are adapted from the Gull Chain of Lakes Association website:

• Please stay at least 150 feet away from loons, if possible.

• Young chicks are unable to dive or get out of the way of boats. If struck by a boat, they will die. 

• Do not separate loon families by boating between them. Loon parents are not able to protect their chicks when separated. 

• Do not pursue loons. Let them decide how close they wish to come to your watercraft.

• Do not circle loons with your watercraft. This is harassment and is subject to a fine from the MN DNR. 

• When pulling tubers, wake-boarders, or skiers do not allow them to get close to or separate loon families.

• Do not feed loons! Loons will start chasing baited hooks and this will endanger their lives.

• Do not cast towards loons. Remember, the best way to observe loons is at a distance with binoculars.

• Fish with lead-free tackle. Lead weights and lures can be ingested by loons when they take up gravel to store in their gizzards. Autopsy data has shown that lead poisoning is a common cause of death for loons.
