Castro Marim
|
In the southeast border with Spain, the mouth of the river Guadiana created an area of mudflats, coastal lagoons and saltmarshes, surrounding the towns of Castro Marim and Vila Real de Santo Antonio. The area is classified as a Natural Reserve (PT) In the wintertime, the temperatures are usually mild, and the area holds a great variety of waterbirds. Waders such as Dunlin, Little Stint, Black-winged Stilt, Avocets and Black-tailed Godwits can be found, amongst other species. Dabbling ducks are also abundant. Other interesting but scarcer wintering waterbirds are Black-necked Grebe, Little Gull and Caspian Tern. Greater Flamingos are present all year round, and Slender-billed Gulls are now regularly seen. Regarding breeding birds, the site has the particular aspect of being the only one in Portugal where Lesser Short-toed Lark occurs. There are also small populations of Eurasian Thick-knee and Little Bustard. Interesting breeding birds also include Pallid Swift, Spectacled Warbler, European Bee-eater and Black-eared Wheatear. In both Spring and Autumn migrations the wetland gets crowded with migrant waders, and a large diversity of migrant passerines can also be found. |
