Figure 5.

This figure demonstrates some of the complexity created by the positioning of the camera for this field experiment. Each image was created by cropping the full frame to just include the area around the bird, and the birds were not resized. These images show the inconsistent orientation of the birds. They also show that the number of pixels needed to show the entire bird varied frame to frame and bird to bird. The images also show that the birdseed containers often obscure parts of the birds
