I just returned from a once in a lifetime trip to South Africa. I saw 458 birds during the 3 weeks I spent there. 78 of them were not included in the program, almost 20%. I found that pretty amazing - they offer a very complete listing in their print edition, they had to go out of their way to omit birds during their transition to software.
Entire families were missing — there are no seabirds of any kind - no Albatross, no Petrals, no Skuas, no Shearwaters, no Storm Petrals or Fulmars and only 3 Terns and 1 Gull. The program is worthless along the coast or off shore. In addition, many of the common names were out of date.
The most amazing omission is that there are no Rock-jumpers, South Africas best known bird and the one people go to there to see.
One of the main reasons I bought this application was for the bird calls. They worked for 3 days. I was not able to restore this feature during the remainder of the trip.
Missing birds and no bird calls are show stoppers. My other complaints were just irritating.
If you use the listing function, you will discover there is no way to edit place names. If you discover that you made a spelling error in the 25 birds you saw "En route Hluhluwe We-umfolozi" and try to edit the location you are presented with a blank space and offered the opportunity to type the whole thing over again just to correct 1 letter — and you get to do this for each of the 25 birds you saw. You are not given the opportunity to just change the incorrect letter, there is no global search and replace function, no ability to copy and paste - nada. Just retype the same thing 25 times.
Even if you notice a mistake while typing an entry, you cant correct it without deleting everything you typed after the error. You cant just insert or move the cursor to the offending letter.
Sasol is making an effort to provide applications of a lot of the Worlds birding locations, which is admirable, but based on this one experience, they are a long way from producing a useable application. I would be hesitant to buy any of them on iTunes because of their no returns / no refunds policy.
