Title
Two Different Methods of Lowering the Head in Extremely Long-Necked Birds
Subject
"Two different methods of lowering the head in extremely long-necked birds. In the swan (above), neck bending starts near the head, as though the neck were a rope passing through a pulley (dark circle). In the rhea (below), bending begins near the body and the head moves up and down like the periscope of a submarine. Shorter-necked birds use a combination of the two methods to extend the neck forward." (Kaiser, Gary). This image is included for evidence within the Natural History and Naturalism Exhibition.
