As part of International Dawn Chorus Day May 7th 2017 I began a series of recorded walks starting at 4:30 this morning, through the South Walney Nature Reserve in Barrow. There are several distinct nesting sites on South Walney which means you have very different bird sounds as the dawn progresses.
I am not an ornithologist so all I can say for certain is that I have the bird sounds of Great Black-backed Gull, Lesser Black-backed Gull, Herring Gull, Greenshank, Redshank, Short-eared Owl, Eider duck, Canada Goose. The recordings were made in grassland, coastal and pond sites.
Eager ears with more knowledge than me will be able to name the other species.
