I went out shooting with a friend today into a nearby parkland. He showed me how you could use an iPod to attract small songbirds to our location simply by playing a selected audio track of the bird of interest using one of the bird field guides we both had bought (Audubon Birds). Here is an image of an American Redstart which I captured today using this approach. It is amazing how well the audio track of this bird attracted them to us.
This was an extremely difficult bird to capture with the Canon Powershot SX40 I was using, because of the bird's small size (the camera had trouble focusing on it) and because of the birds tendency to move about frequently (made harder to capture by the camera's shutter lag). I have found the SX40 works well for larger birds as long as they are not in flight.
