Just wanted to mention that there are free guides (printable pdf files) of Australian Raptors available at the Toowoomba Bird Observers' "Downloads" page. Click here: raptorguides
I put them together with the help of other, kind photographers and I hope to update them every so often to get them better and better...
I have tried to set them out so they are user friendly in the field and hope you will find them interesting and useful.
Check out the Toowoomba Bird Observers' Website when you're there!
