Did you know?
- Britain hosts about 10% of the world's Chinese water deer (British Deer Society).
- Both sexes have tusks (shorter in does); a buck's can hang about 7 cm below the lip, far longer than a muntjac's (Mammal Society).
- Does can breed at one year old, the youngest of British deer (British Deer Society).
Moments worth waiting for
- Rut
A buck barks and squeals, chasing a doe across the marsh. - Fawns in the reeds
A tiny spotted fawn lies frozen in the sedge as its mother feeds nearby.
Rare forms and local legends
- Black water deer
Only two melanistic Chinese water deer are known anywhere in the world, both in Norfolk: one in winter 2023–24 and one on a trail camera in October 2025.
Photo tip
Use a long lens at dawn from a fixed spot; expect a low sun and dew-lit reeds.
Be a good naturalist
Do not chase or approach; fawns are hidden in cover and should not be touched.
The law
Non-native, so not protected as a species, but the Deer Act 1991 (England and Wales) sets a close season of 1 April–31 October for bucks and does, and poaching is an offence.
