Acheloos estuaries – Circus aeruginosus / Sterna caspia / Larus genei
The observation of a Circus aeruginosus (Western Marsh Harrier) isn’t a surprise, but a raptor observation could always be interesting. Here at its typical flight, patrolling over the reeds.
Aquila heliaca, Aquila clanga (one of them the fulvescens morph), Circus cyaneus, Falco peregrinus, Accipiter nisus, Buteo buteo, Falco tinnunculus, Falco columbarius were the other raptors species that were observed during midwinter monitoring at Mesollogi-Acheloos area.
Sterna caspia (Caspian Tern) and Larus genei (Slender billed Gull) are common winter visitors (especially the second one) at Mesologi-Acheloos area. In general are rare species with a limited-localised distribution.
