Birding checklist
When
238 species, 7 Sep 2024 to 8 Aug 2026. The line climbs one step for every bird seen for the first time; each dot is that first sighting.
Read across, the box scrolls sideways; read down, it is a hanging scroll and the page itself scrolls. Tab once to reach the sightings, then use the arrow keys to move from one bird to the next, Home and End for the first and last, and Enter to open one.
