Brent Geese

As promised, Brent Geese. These birds winter here in large numbers especially at Pagham harbour and can be seen flying in groups made up of thousands of individuals. It was recently discovered that  birds such as these, when migrating not only fly in that trademark arrow formation to save energy but also but they also time their wing beats. One will time its downward motion so as to take advantage of the gust created by the goose in front of it. This means that they can migrate further without stopping due to them being more energy efficient. These particular geese come all the way from Siberia.
