Devoted birders know, even in the digital age, there is no better "handheld gadget" by which to record one's avian observations than an old-fashioned notebook. Of course, a few organizational upgrades never hurt! Created by acclaimed ornithologist and bird-guide author David Allen Sibley, The Sibley Birder's Life List and Field Diary is divided into three lists: one for making detailed entries about specific bird sightings (date, location, etc.), organized by species in taxonomic sequence; one checklist by species (more than 1,000 found in North America!); and finally one "life list," for recording your sightings chronologically. Measuring 5"x7½", with waterproof covers and a spiral binding that opens flat, the notebook is an indispensible tool for bird-watchers looking to build a comprehensive keepsake field diary.
