These are greylag geese and goslings at Wroxham Broad, a lake on the Broads National Park in Norfolk, England.
The greylag goose (Anser anser) is the ancestor of most domestic geese, and the largest of the wild geese native to the UK and Europe.
So how about some figures?
Well, they weigh up to 3.7 kilos, they’re up to 89 centimetres long with a wingspan of up to 1.8 meters.
And males are typically bigger than females.
They travel to their northerly breeding grounds in spring, nesting on moorlands, in marshes, around lakes and on coastal islands.
They normally mate for life and nest on the ground among vegetation.
The female typically lays a clutch of 3 to 6 eggs; she incubates them and both parents defend and rear the young.
The birds stay together as a family group, migrating southwards in autumn as part of a flock, and separating the following year.
During the winter they occupy semi-aquatic habitats, estuaries, marshes and flooded fields, feeding on grass.
Some populations, such as those in Southern England and in urban areas, occupy the same area year-round.
