This study focused on bird species in Taiwan and used content analysis to explore the presentation of ecological information across three design forms: two-dimensional catalogs, infographics, and smart phone apps. The reliability test conducted by two coders yielded a reliability score of 0.99, 0.97, and 0.98 for two-dimensional catalogs, infographics, and smart phone apps, respectively. These results imply that (1) 2D catalogs present the greatest amount of information with the highest information complexity, followed by smart phone apps and infographics. (2) The use of pictorial illustration comprehensively displays the visual elements; the use of graphic symbology helps users search for information, and graphic rendering can be used to enhance the visual characteristic of birds. (3) Designers can introduce adequate functions and interface designs during app development to improve user convenience when browsing and recording bird characteristics.
