Over and above the GPS location, you can search by shape, type, colours, size, where seen, bird calls and more. There are 100's of attributes you can choose from, which makes identifying a bird accurate and easy. As a first ever bird app achievement, the resulting bird list is sorted by relevance with the most probable birds matching your search criteria at the top, which makes it extremely quick and accurate.
