Prince Harry Ginger Bearded On His Birthday

9/15/2015 10:55 AM PDT

Prince Harry spent the summer working in Africa on conservation projects and the bush seems to have rubbed off on him.

Harry was back in the UK Tuesday ... where he celebrated his 31st birthday doing royal duty, but all eyes were on his new beard.

It might be compensating for that royal receding hairline. Getting older ... never fun for anyone, even Prince Harry.
