About anaglyph 3D: Photographs here are in 3D, using anaglyph techniques which combines two photographs one in red and the other in cyan (blue + green) color. To get the 3D effect, you must use glasses with red and cyan lenses (filters) over your regular glasses. The form of the beak is far easier to interpret in 3D and we strongly recommend to the viewer that the glasses be obtained (this is especially helpful when viewing enlarged images - i.e. click on the image). These beak photographs were made using Red and Cyan Anachrome Aviator Glasses (see: http://www.anachrome.com/glassbuy.htm or http://www.amazon.com) which cost under $10.00 (USD).
About A. lesueurii lower beaks:
- Shape: Typical shape but with a short hood (CL/HL: x¯= 2.0; BH/HL: x¯= 2.8) (n=3).
- Lateral wall: Lateral-wall fold present, not thickened (Clarke, 1986). Fold reaches posterior edge of lateral wall well above free corner.
- Rostrum: Rostral base about equal to jaw edge in profile (RB/LReL: x= 1.1; n=3). Jaw edge nearly straight, often with a hook at tip. Rostral tip rounded in oral view.
- Hood: Short hood with broad notch above broad crest.
- Shoulder: Rather wide, simple shoulder-blade becoming a low tooth in adults. Shoulder-blade covered or nearly covered in young beaks by hyaline matrix of wing fold. Thin "white line", of uncertain significance, may be found in young beaks.
- Wing: Wing length average. Wing-fold does not extend onto rostrum.
