A few minor glitches but overall very good
Other than the program shutting down when looking at rare bird sightings when clicking on the bird and saying Prince Edward Point National Wildlife Area is in Kingston (which it isnt) the program really well.
The program has a great list of birds with several search options and an excellent collection of male/female/juvenile photographs
For the price of nothing it rates a very high 5 stars in my books.
