Becky, that IPad mini will really come in handy! How fun to play the bird calls and have them come to the garden, I never would have thought of doing something like that and it's a great idea! I'd love an IPad Mini and might ask my hubby for one for my next birthday.
It would be nice to have something lightweight and easy to handle/carry. He has an IPad (I'm pretty sure it's the Mini) that the University supplied for him and it's really nice.
Keep us posted if you get an ID on that bird!
