If you use the logic grid, you can mark off which camera took which photo.

The oldest camera is the earliest photo. The earliest time is 6:25am. The oldest camera is Gloria. The picture of the frog says Gloria on the bottom. Therefore frog = 6:25am.

The cameras on the island took photos before 9am. The cameras on the island are cameras 2 and 3. Therefore camera 1 took the photo at 9:43am.

As we already know that the frog was photographed at 6:25am, this means that the frog was NOT photographed by camera 1.

The otter was photographed on the south side of the island. From the map we see that this is camera 3. Therefore otter = camera 3.

We know that the frog was photographed at 6:25am, and that the other camera on the island took its photograph before 9am. The only other time before 9am is 8:02am. Therefore camera 3 = otter = 8:02am.

By the process of elimination, that means that camera 1 must have photographed the kingfisher at 9:43.
