If you're not exactly sure what species you have photographed, please enter your best guess for the name of the species. E.g. Koala, Swamp Wallaby, Cracticus torquatus (Grey butcherbird), etc. A drop down menu will appear from the species name box.
When you select a name from the list, a link (and sometimes an image) will appear on the right hand side showing you the species page in the ALA. You can view more images of that species on the species page to double check if that's your species.
If the initial identification is incorrect, it may be updated and clarified by other ALA community members or experts.
