Bird Data combines information from IOC 8.1, IUCN Red List, and other databases for all of the world bird species. Data can be filtered by countries. Data includes bird names in seven languages, subspecies, ranges, alternate names, IUCN status, and taxonomic hierarchy. The last version has links to thousands of bird songs and bird calls that can be downloaded to the device.
Also included is a map feature that ties into the eBird Hot Spot and sighting database. See where your target species have been seen recently, or explore sightings at nearby locations.
