GR153 Ornithological Importance The reasons for this absence remain unknown, although competition for nesting sites and pray with the Yellow-legged Gull, in association with emigration to other neighbouring breeding populations in “Mikres Kyklades” (GR253) and Mykonos (GR197) is considered most probable. This is one of the few sites where all three species of Procellariiformes occuring in Greece breed. Mixed colonies of both Cory’s and Yelkouan Shearwaters have been identified on two different islets. The area holds one of the most important Cory’s Shearwater colonies in the Cyclades (100160 pairs) and a smaller but significant Yelkouan Shearwater population (20-50 pairs). The nesting

This site is important for the breeding populations of 5 seabird species. The Mediterranean Shag breeds along the rocky coast of Paros and Antiparos but also on most of the surrounding islets. The breeding population numbers 50-65 pairs, with their nesting sites sparsely located along the coast. Postbreeding congregations of up to 65 individuals have been recorded in the coastal waters of Paros and Antiparos. Breeding of the Audouin’s Gull was first recorded here in 1996 on two uninhabited islets. The breeding population trend was relatively stable up until 2001, however since then the colony size declined drastically, being absent during the last few years.
