Yesterday I saw this visitor in my garden. It is a Peach faced Lovebird (Agapornis roseiicollis), also known as Rosy-faced Lovebird. It's native range is in southwestern Africa, and more specifically Namibia and Angola.
As I found in the www, Peachfaced Love Birds are the most common Love Bird species in captivity. There are of at least seventeen distinct Peachfaced mutations, allowing well over 100,000 possible color combinations!
