Your Favorite Places

We've partnered with the Cornell Lab of Ornithology and use their online checklist program, eBird, to help you find and identify birds. Now you can download lists of birds right into your Peterson Birds app and create customized lists for your birding adventures.

Bird Finder lists are organized by location and state and include frequency data that indicates how often birds have been recorded at this location. This abundance data is a collection of all sightings submitted to the Cornell Lab of Ornithology eBird database.

Abundance by Week

Abundance information is stored for every month, with four (4) marks roughly corresponding to weeks in the month (see Key on left).
