Lists of North American birds are accessible online through Audubon.org and NationalGeographic.com. The Audubon list is accessible by selecting Birds of North America Field Guide from the Birds header at the home page of the website. The National Geographic Backyard Birds A-Z list is viewable at animals.nationalgeographic.com/animals/birding/backyard-birds-all/.
Below the day's Featured Bird, Audubon includes an alphabetical list of birds and a color picture of each species. Clicking on the Volume icon plays the distinct sound of each bird, while selecting the creature itself brings up information on the range, habitat, diet and feeding and nesting behaviors of each species. Birdwatchers can immediately locate information on a specific bird by typing the species into the search box and may also filter the list by Family or Region.
The National Geographic list includes 150 of the most common backyard birds across North America. Selecting a species from the alphabetical list displays information on the identification and variations of each species, list of similar species, seasonal ranges and other pertinent facts. The Audio feature also plays the song of each bird. Additionally, the Backyard Bird Identifier Tool is a helpful link that enables birdwatchers to identify any of the birds in the database by answering four simple questions.
