A sequence of three photographs will appear showing various angles of the same animal. For animals difficult to find, there will be a fourth photograph provided that shows the animal's movement. Note, that photos taken at night will be in black and white. Once you recognise the animal, use the keyboard shortcuts or click the option on the right hand side of the screen to select your choice and your confidence level.

If you know the species of the animal in the photos, please tell us in the comment box (i.e. blackbird or ship rat). You can also use the comment box to write about anything interesting or unusual in the photos.

When you are done, click submit (or press enter) and another set of pictures will appear.
