Very Good App but occupies too much internal memory, does not work after moving to SD card (ext. memory)
It should be very helpful. However, I can neither see the pictures nor hear the bird calls with Galaxy S4.
excellent excellent for ppl who are bird lovers and want to explore more about hk birds!
Can't find the bird's tracks, but it is a nice application
Too big, and i can't see the pictures or hear the bird's song on my nexus 5
All birds need its roar
