STRENGTHS AND WEAKNESS iBird Audubon Nat Geo Sibley Peterson
Strengths Search engine, zoomable images, large amount of data per species, has both photos and drawings. Nice photos from Vireo, good species details, , multiple song vocalizations. Good species information, consistancy of artwork. Large number of drawings per species, excellent Sibely art, large number of bird calls, compare 2 birds. Low cost, quizzes.
Weakness Needs more female and juvenile illustrations, needs improved life list features. No illustrations, complex UI, life list feature shows promise but does not work correctly with web site. Only app with no search engine, can't zoom images, no photos, weak UI. Illustrations can't be zoomed abd are not full screen size, weak search engine and UI. No search engine (search by ZIP dysfunctional), poor UI, illustraions show paint streaks when zoomed.
NOTES
