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 Мартин середземноморський, Мартин малий, Мартин скельний, Мартин гренландський, Мартин полярний or even an American vagrant like a Мартин делаверський. American Чирянка мала and Свищ американський can also be seen among the thousands of native teals and Свищ євразійський. In autumn and winter, among the more common waders, including many Сивка звичайна, there could be Коловодник чорний, Косар білий, Побережник червоногрудий, Побережник малий, Коловодник болотяний, Брижач or an American wader like a Побережник арктичний. 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 Крех великий and Крех середній. All five of the world's diver species have also been seen there. The area is also good for Рибалочка блакитний and it's worth visiting the hide at Ryan's field for a chance to see one as well as the resident Кульон великий. In late summer, you may see an Скопа visiting the estuary if you're very lucky.
