After at least two sea gulls were found shot and three others were injured in Playa del Rey and Manhattan Beach, the Humane Society of the United States has offered a reward of up to $2,500 for information leading to the arrest and conviction of anyone involved in the shootings.

The five injured sea gulls were found in the Playa del Rey and Manhattan Beach areas Monday and Tuesday, November 12th and 13th, and they were taken to the International Bird Rescue and Research Center in San Pedro for treatment, said Rachel Newman, wildlife rehabilitation technician at the center.

Two of the birds were found with BB gunshot wounds but all five had injuries consistent with gunshot wounds, including wing fractures, Newman said. Four of the sea gulls were injured so severely that they had to be euthanized, she said.

“The wing was completely twisted around,” Newman said of the birds’ injuries.

The birds appeared to have been healthy prior to the incidents, she noted.

Bird Rescue and Research Center staff believe the injured birds from Playa del Rey and Manhattan Beach to be from related incidents because they came from the “same general area and within a small timeframe,” Newman said.

Newman said it is not uncommon to find birds with those type of injuries but added that it’s unusual for the incidents to occur within such close proximity of each other.

“We usually don’t see it that concentrated,” Newman said.

The Humane Society of the United States offers rewards in animal cruelty cases across the country and works to strengthen laws against animal cruelty.

“All birds are worthy of our protection and the perpetrator(s) of these crimes needs to be brought to justice,” Paul Bruce of the Humane Society West Coast Regional Office said of the local incidents.

The California Department of Fish and Game is investigating the case.
