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 Crnoglavi Galeb, Mali Galeb, Galeb klaukavac, Iceland Gull, Glaucous Gull or even an American vagrant like a Delaverski galeb. American Kržulja and Američka zviždara can also be seen among the thousands of native teals and Zviždara. In autumn and winter, among the more common waders, including many Troprsti Zlatar, there could be Crna Prutka, Žličarka, Krivokljuni Žalar, Mali Žalar, Prutka Migavica, Pršljivac or an American wader like a Pectoral Sandpiper. 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 Veliki ronac and Mali ronac. All five of the world's diver species have also been seen there. The area is also good for Vodomar and it's worth visiting the hide at Ryan's field for a chance to see one as well as the resident Veliki Pozviždač. In late summer, you may see an Bukoč visiting the estuary if you're very lucky.
