Mwah

"Walk slowly and quietly. Do not wear brightly colored clothing. Your parked car can serve as a blind and birds will approach closer than if you are on foot. If you are quiet and partly concealed, you can often attract songbirds and draw them close to you by repeatedly "pshshing" or "squeaking" or noisily kissing the back of your hand."
