Description
Winter is the best time to visit Hayle, as the number of birds in the estuary can be up to 18,000. Among the gull flocks, you can find čajka čiernohlavá, čajka malá, čajka žltonohá, čajka bielokrídla, čajka bledá or even an American vagrant like a čajka obrúčkozobá. American kačica chrapka and kačica bielohlavá can also be seen among the thousands of native teals and kačica hvizdárka. In autumn and winter, among the more common waders, including many kulík zlatý, there could be kalužiak tmavý, lyžičiar biely, pobrežník krivozobý, pobrežník malý, kalužiak močiarny, bojovník bahenný or an American wader like a pobrežník škvrnitý. Several different tern species can be seen on spring passage. The estuary is best viewed from the causeway bridge or the path around Carnsew Pool, which is favoured by potápač veľký and potápač prostredný. All five of the world's diver species have also been seen there. The area is also good for rybárik riečny and it's worth visiting the hide at Ryan's field for a chance to see one as well as the resident hvizdák veľký. In late summer, you may see an kršiak rybár visiting the estuary if you're very lucky.
