I recorded a large flock of Geese at Campfield Marsh yesterday; I think they were Barnacle Geese. There is a blog entry below that describes this, and also you can listen to the recording there if you wish. There are other similar recordings on this blog, and more to come as the year goes on. http://www.amissio.uk/2018/02/24/23-2-18-flock-of-geese-at-campfield-marsh/
