I have just finished reading a book about radio-tracking Peregrine Falcons. The book is called "On the Wing: to the Edge of the Earth with the Peregrine Falcon" by Alan Tennant. The author has a webpage where you can find out more about his book.
I'm glad my cockatoos don't cross several country borders and that the data comes via satellite and doesn't require me to follow them in a light aircraft. I can definately relate to the sense of attachment to my study birds that is described in the book. It is something special to have a window into the life of a wild bird and try to understand its movements by what you see.
