Perhaps part of the answer lies within non-visual clues. A theory raised by Papi and his co-workers concerns the pigeons’ use of olfactory navigation. They suggest that pigeons create an olfactory or scent map, cataloguing smells from birth. Different smells alert them to varied directions: sea, forest and cities. In their early life, they associate odours with the direction that the odours come from. When they are being moved from an area (for example, being transported to a race), they store up the odours, and reverse them on the return flight for the direction of home.

After each target letter was used for four sessions, a new target letter replaced it. The data, in this case the errors, was arranged in hierarchical clusters and as a two-dimensional representation. Letters that look similar, such as ‘u’ and ‘v’, scored a high rate of error (34 per cent). ’39 In studies by a team at Keio University, Japan, pigeons have been credited with similar levels of intelligence to those found in 44 Jasmine, a whiteheaded pigeon. a three-year-old child. Each pigeon test subject was shown live footage of itself, and then there was a delay of several seconds.
