iBird Ultimate is our most birding advanced app. It comes with the two advanced features built in: “Birds Around Me” (BAM), a feature which restricts the birds to just those found in your current GPS area and the patented “Percevia™ Smart Search” feature which gives anyone the skills of a bird identification expert. If you are not sure you’ll need these features you can try iBird Pro, a less expensive app which offers both these as in-app features you can buy at any time. iBird Plus is like Pro but has half the search attributes. iBird Ultimate also takes a major leap forward with “Time of Day” filtering available in version 10.04. You can now search for birds by activity levels during day or night (Cathemeral), dawn and dusk (Crepuscular), during the day (Diurnal) or during the night (Nocturnal).
