Bird prints by L Fisher - seeking info on artist

I have just bought these prints from a second-hand shop which was closing down.  They're just ordinary prints, not limited edition, but I like them because they're lifelike while also having a gentle humour to them.  I would love to know more about the artist, and wondered if anyone has heard of him/her.  (They are in ordinary brown frames but I took them out to clean the glass, which is filthy!)
