“It’s happened three times this year because of iguanas” in Lake Worth Beach, he said.Iguanas are extremely adept climbers and have large bodies – a combination which makes the reptile a bigger threat to electrical equipment than birds or squirrels, according to Kerr.“Unlike birds, the tail and sheer size of iguanas” allows them to make a connection between two parts of the electrical system, he said.Green iguanas are not native to Florida but began to appear in the state in the 1960s, likely escaped or released from captivity, according to the Florida Fish and Wildlife Conservation Commission.The reptiles are considered an invasive species “due to their impacts on native wildlife” and legally can be humanely killed on private property, the commission said."
