Red tide linked to royal tern deaths on causeway

On Feb. 16, the Sanibel-Captiva Conservation Foundation reported that many residents and visitors have called SCCF, the city of Sanibel and Clinic for the Rehabilitation of Wildlife with concerns about royal terns over the past few weeks and the sight of their carcasses on the Sanibel Causeway bridges. Test results on deceased royal terns confirmed on Feb. 15 that they had high levels of brevetoxins, the neurotoxin associated with red tide.
