It was around 7:15 p.m. Thursday when Kiii News Producer Eddie Cruz happened to be driving near the Port Ayers bus station and spotted a mass exodus of bats.They came from a business on the 4300 block of Port, where the owner of that business said the winged visitors have made a home for at least a dozen years."They'll fly out of here by the thousands! Thousands!" said Ronnie Gibson, owner of H&L Automotive. "There must be 10,000 of them in there."You would never know the bats lived there if it wasn't for the guano they leave behind. There's so much of it that bat enthusiasts often visit the location to scoop up the nutrient-rich fertilizer.The bats can been seen leaving their roost nightly between 7-7:30 p.m.
