eBird Illustrated Checklists transform your eBird contributions into a dynamic digital bird guide for anywhere in the world. Choose a region or hotspot, and the Illustrated Checklist combines sighting frequency (e.g., the proportion of complete eBird checklists reporting the species each week) with photos and sounds from the Macaulay Library. The Best Quality rating is used to determine which photo and sound is shown for the selected region. No photo or audio? Add your own to help fill in the gaps!
