Pigeons never forget a face

New research has shown that feral, untrained pigeons can recognise individual people and are not fooled by a change of clothes. Researchers, who will be presenting their work at the Society for Experimental Biology Annual Conference in Glasgow on Sunday the 3rd of July, have shown that urban pigeons that have never been caught or handled can recognise individuals, probably by using facial characteristics.

Although pigeons have shown remarkable feats of perception when given training in the lab this is the first research showing similar abilities in untrained feral pigeons.

In a park in Paris city centre, pigeons were fed by two researchers, of similar build and skin colour, wearing different coloured lab coats. One individual simply ignored the pigeons, allowing them to feed while the other was hostile, and chased them away. This was followed by a second session when neither chased away the pigeons.

The experiment, which was repeated several times, showed that pigeons were able to recognise the individuals and continued to avoid the researcher who had chased them away even when they no longer did so. Swapping lab coats during the experiments did not confuse the pigeons and they continued shun the researcher who had been initially hostile.
