I got a bird feeder for Father’s Day and this morning was surprised and delighted to see what appeared to be green parrots at the feeder.
After an internet search, it turns out they are Peach-faced Lovebirds. Although native to the Namibian desert in southwest Africa, they have escaped from captivity in many parts of the world and feral birds dwell in Arizona and London.
Peach-faced lovebirds are the most common lovebird held in captivity.
Here is a neat page about peach-faced lovebirds in greater Phoenix where the photo above comes from.
And here is a neat map of sightings of peach-faced lovebirds in Arizona.
