During October around the estuaries of the East and South coast of England Dark-bellied Brent Geese (Branta bernicla) can be observed. They arrive from the Baltic and stay until March.
Some 90,000 plus visit during that period. They are not much bigger than a Mallard in reality. They eat eelgrass, field grass, cereals and other crops found on farmland where they visit during the day and return to the shoreline at night.
These images were taken at Titchwell Marsh Reserve in Norfolk this week.
I will be posting other observations as and when I can get them sorted out.
