iOS Universal Reference
Field guide to Australian Birds based on the Gaia Guide website (http://www.gaiaguide.info/).
Almost all species descriptions include several identification photos. The descriptions also include distribution maps. A growing number of descriptions include recordings of bird calls. Along with descriptions of distinguishing features, details of size, habitat preferences, diet and other details, this information provides an increasingly effective means of identifying birds 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 of species with size and wingspan data 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 (http://gaiaguide.info/).
The screen layout scales better for smaller devices.
Filtering by name, colour, size, wingspan and location works more reliably.
Work back in your ID process from a single species: tap on the colour swatches in that species' description to indicate the colours of the specimen you saw. Then navigate directly from the link in the species description back to the branch of the field guide containing the single species and filter from there to find other possible matches. Add location information to your filtration to make the search even more specific.
