There are several tern species that breed in Iran during summer. Usually they nest on safe and uninhabited islands of the Persian Gulf. Here, we report an unusual occurrence at the Iran-Reshadat shipwreck ~10 km from Imam Hassan port in Bahregan Bay, Bushehr Province. At this site, Bridled Terns had laid eggs on the sunken ship upon three deck pillars that reached ~8 m above high water. Despite fishing boats anchoring around the sunken ship and even tying to the pillars, the terns appeared to feel safe and continued to nest at this location.
