An image but not really intended first and foremost to be a wallpaper. Still, I have it set as my background. It shows an Argentinian Monk parrot sitting on a gothic structure in Green-Wood Cemetary in Brooklyn. I've posted about these parrots way back. They've adapted to the harsher environment after believed to have escaped an airplane in the 1960s. Think I'll go back and see if the colony is still around. They've adapted to the climate quite well.
