Yearbird

A desktop application for exploring and analysing your personal eBird data and your personal photos of birds.

Yearbird lets you filter, browse, and visualise your personal eBird sightings in ways the eBird website does not — across every location, species, date, and season in your personal history. If you are a bird photogrpaher, Yearbird also lets you sort, filter and view your photos in the same way.
