No, the Macaque doesn't own copyright as the USCO ruled that only works created by a human can be copyrighted under US law, which excludes photographs and artwork created by animals or by machines without human intervention and the UK Copyright Designs and Patents Act 1988 (CDPA) stated that the author of a work is the person who creates it. As a monkey is not a person under UK law, it cannot be an author, and therefore cannot be the owner of the disputed images..
The Intellectual Property Office (IPO) also indicated that under UK law animals cannot own copyright.

But yes, it's all rather silly and the sort of silliness which can at times take all the fun, spontaneity and love out of life.
