If I were to bet who would win a fight between a bald eagle and a common loon, I would put my money on the eagle. I would win that bet 999,999 times out of a million, but there are always outliers. The one in a million fight took place in Maine between a bald eagle and a loon where the loon won.
According to Global News, a bald eagle found dead in Maine last year was killed by a vicious peck from a loon, according to the results of a recent autopsy by the Maine Department of Inland Fisheries and Wildlife.
A bald eagle was found dead floating in the water. It was scooped up by the Maine Fish and Wildlife where they first thought it was shot, but on further investigation determined that a loon stabbed the eagle in the chest with its beak causing it to die.
Wildlife biologist Danielle D’Auria stated in a blog post that bald eagle often prey on loon chicks and the eagle death is very probable to have been caused by a loon defending its young
“This puncture wound could have been due to an adult loon’s beak as a result of its attempt to protect its chick from the eagle. A loon’s best weapon is its dagger-like bill, and it will often attack adversary loons by coming up from beneath the water’s surface with its bill straight towards the other loon’s sternum, or chest. Many adult loons have several healed-over sternal punctures from fights like these.”
This is the first time an event like this has been documented.
