When I started observing, photographing and recording birds, I thought I needed a way to organize the information for myself. What did I see when? Did I ever see or hear that bird before? Where else is there information online about it? As a years-long Java application developer, I wrote some code to generate this information systematically on my web site. Maybe these pages will be of interest or use to someone else too.
