Polichnitos Salt Pans

Polichnitos area

  • It is located north of the Skala Polichnitos, just next to the last houses of the village
  • Together with adjacent wetland areas (saltmarshes and seasonal ponds), it forms a 96 hectares wide wetland- nearly half the size of the Kalloni Pans.
  • This week the usual overwintering bird species are recorded here: Avocets, Flamingos, Shelducks, Black Storks, etc.
  • It is a paradise for shorebirds, year-round. Also a very popular site for birders thanks to a drivable track that runs its perimeter, enabling the best of views and from a close distance.

Alykoudi marsh

Polichnitos area

  • It is located 3 km NW of the Lisvori village (east coast of the Kalloni Gulf).

  • It dries out during summer to be flooded again the following winter.
  • In winter, the usual overwintering species are recorded here: Flamingos, Shelducks and other ducks, Yellow-legged Gulls, etc
  • Alykoudi marsh is a very rewarding site to observe waders and other wetland birds during their spring passage (which is about to start!!) and an important breeding area for the Pied Avocet, Kentish Plover, and the Black-winged Stilt.

Messa wetland

Agia Paraskevi area

  • The third-largest wetland of the island (1,4 sq. km) and is located by the main Mitili-Kalloni road and the conjunction to Achladeri (to Polichnitos).
  • It is formed by several different types of wetlands such as a lagoon, 2 torrents (Kalami and Kryoneri), salt and fresh water marshes, and the coastal zone!
  • During autumn and winter, it takes a marron color thanks to the plant Glasswort (Salicornia europea), a special plant of the habitat “Mediterranean salt-marshes” that is tolerant to salt.
  • In winter, the usual overwintering bird species are recorded here: Greater Flamingos, Ruddy Shelducks, Wigeon, Dalmatian Pelicans, herons, cormorants, Little Grebes e.t.c.

Kalami marsh

Agia Paraskevi area

  • It is located at the western parts of the Messa wetland, in the Agia Paraskevi region, right at the conjunction of the main road towards Achladeri and Polychnitos.
  • It is formed by the torrent Kalami as it becomes blocked by the coastline and, in contrast to most of the wetland area, it is formed by freshwater.
  • Only the parts of the estuary retain water through the summer months, in most years.
  • Flamingos, Shelducks, Mallards, Coots, Green Sandpipers, Kingfisher, etc. were recorded there, a few days ago.
  • It is an excellent site to observe migrating waders, herons, and waterfowl during the spring passage – that has already started!
  • This wetland is a breeding area for the Little Ringed Plover, Coot, Water Rail, Mallard, Black-winged Stilt, Zitting Cisticola, the Eastern Speadfoot, Levant Water Frog, and several species of Damselflies and Dragonflies.

Milopotamos estuary

Agia Paraskevi area


  • The river is located 2,5 km to the SW of Agia Paraskevi and its estuary is between the Kalloni Salt Pans and the Messa wetland.
  • Milopotamos River springs are found within the pine forest and it is formed by two tributary streams that meet 4 km away from the sea.
  • The estuary, which is 0,70 hectares wide, joins with one end of the peripheral canal of the Kalloni Pans.
  • A few days ago, Flamingos, Cormorants, yellow-legged, Black-headed and Slender-billed Gulls, Greenshanks, Kingfishers, etc. were recorded here.
  • It is an exceptional site to observe migrant birds as the river vegetation is left relatively intact (reeds and tamarisks).
  • Every year, the estuary and lower parts of its bed support breeding pairs of Little Ringed and Kentish Plover, Ruddy and Common Shelducks, Nightingales, Olivaceous and Cetti’s Warblers, Bee-eaters, etc.
