I am a beginning birder and I have found this app to be excellent for tracking your observations. There is also the ability to export your observations to eBird cvs format and the import is simple. A very useful app.
Update: I have used this now on several bird walks (checklists are great for this) and for day to day observations. I continue to be inpressed with what a good job it does and the integration with iBird Pro is wonderful.
