Background or the background is a very important element in the photos you produce.

The uniformity of the color blue in the background leads your eyes focused on the main object of the birds, and even green color contrast around the eyes to appear more alluring. Background color harmony with the main object to make a photo look better.

Background once again is a very important element in the overall photo. The average one photograph has a fairly extensive background area even up to 60% of the overall picture fields. You can never have a cool photo, if you background photos look confused and chaotic.

Good luck!
