When I learned about this, I was told that it was instinct. {Instinct continues to be the explanation of choice whenever animal behavior implies too much intelligence.} Instinct, though, wouldn't go very far in explaining how pigeons use human transportation routes to navigate. Pigeons follow highways and take particular exits, likely following many of the same landmarks as the humans driving below.
In "Eating Animals," Jonathan Safran Foer discusses the concept of instinct as it relates to animal behavior, particularly in pigeons. When attributing intelligent behaviors to animals, instinct is often the primary explanation. However, this notion falls short when examining how pigeons navigate urban landscapes, specifically by utilizing human transportation systems.
Pigeons not only follow roads but also take specific exits, indicating a level of awareness and understanding of their environment that transcends basic instinct. They appear to rely on the same landmarks that human drivers use, showcasing their ability to adapt and learn from their surroundings rather than solely relying on instinctual behavior.
