This is a task in gimp image manipulation program
I used first a nother background, her you can see a working progress.
The background photo is one of my own, and the tow next one I got from a web site named: flickr.
I started out with a leaf to indicate the time of the year: autumn. I played with curves and saturation tool to get the right collars. Then I added this bird as a shadow, mostly because I did not want it to steal all the attention from the collars in the background. And I thought that by using its shape as a shadow you focus on the lines more and makes an illusion of a bird, with no feeder texture.
I was trying out filters and came across this blurry filter that makes the images seems like they lies under water. I used this filter on the background since it did not disturb the collars and at the same time makes the straw layer blending in fine.
In the text “bird shadow” I used autumn collars and drop shadow in a way that made the text stand out from the background but not take too mouth space.
