Field guide to birds found in the United States of America. Whether you are a keen birder or just have a passing interest in the birds found in your local area, this field guide will be a useful addition to your mobile device.
The birds included in this guide are based upon the Avibase (https://avibase.bsc-eoc.org/) species list for the United States. It includes a number of species that are only found in captivity or because of escapes from captivity.
Almost all species descriptions include several identification photos. The descriptions also include distribution maps. Along with information about distinguishing features, details of size, habitat preferences, diet and other details, this information provides an increasingly effective means of identifying species that can be found in Australia.
To use the guide, drill down though the species groups to find a group that you think is likely to contain the species you have observed. Then you can tap "filter" to see all identification images for species in the chosen group. You can refine the filter via the filter tab, selecting only those species that have the chosen colours. The required accuracy of the colour filter can be adjusted to refine or broaden the number of species that match your search. For groups with size and wingspan data, such as the raptors, you can also filter based upon size and wingspan estimates.
Once you find an image that matches, view the description details for that species to confirm the identification. Confirm by tapping the + icon to add a new record. Fill out your record details, add a sound recording or photo as evidence, then upload the record to the server so that it can be kept for posterity and shared with others.
The information in this app is the result of collaboration by many contributors. All users of this app are welcome to contribute to the quality of the app by adding descriptive details, identification photos and sound recordings. If you have knowledge that would improve the usefulness of this app. please consider adding it via the Gaia Guide website (https://gaiaguide.info/).
