If you want to add a touch of drama to your landscapes, a well-placed bird or two can go a long way. Open the bird image in Photoshop, grab the Object Selection Tool and click on the bird (Shift-click to add other birds to the selection). Go to Select > Select And Mask and increase Radius to improve the selection. Once done, press Cmd/Ctrl+C to copy, then go to your landscape image and press Cmd/Ctrl+V to paste it in. Press Cmd/Ctrl+T, then use the box to resize and rotate the birds into position. For a more cohesive look, press Cmd/Ctrl+L for Levels, then drag the white or black output slider inwards to fade the shadows or highlights.
