Photographers have captured endearing images of grey seal pups at Donna Nook Nature Reserve.
The site lies on the Lincolnshire coast near Louth and attracts hundreds of visitors each year.
The pupping season typically runs from October to December.
This year, 1,924 pups were born at the reserve.
That figure is 274 higher than last year, which saw a notable decline.
Lincolnshire Wildlife Trust said the increase was encouraging.
All adult seals have now returned to sea.
Twelve pups remain visible from the public viewing area.
