Spatial Memory In Pigeons On A Four-Arm Radial Maze, Robert H.I. Dale

Subjects were forced into three arms, then permitted two choices to enter the remaining ann. Five subjects chose accurately (90% correct) with delays of 5 min or less, their choices depended on extramaze cues, and the food in the target arm provided no essential cues. After an incorrect first choice, subjects' second choices were more accurate than chance. These data suggest that, while spatial memory has many similar characteristics in rats and pigeons, pigeon …
