Quick takeaways
Rats exhibit intelligence and adaptability in urban settings, nesting underground and feeding on a variety of items.
The pandemic altered rat behavior in urban areas, leading to increased aggression and dispersion in search of food.
Urban rat myths often exaggerate their size and behaviors, but rats are resilient, possess unique adaptations, and adapt to regional food sources.
Deep dives
Rat Biology and Habits in Urban Environments
Rats exhibit intelligence and adaptability in urban settings. They communicate through vocal sounds, ultrasonic sounds, and pheromones. Nesting underground, they construct burrows with escape routes. Rats feed on a variety of items and show social interactions, such as grooming and fighting.
Impact of the Pandemic on Urban Rat Behavior
The pandemic altered rat behavior in urban areas as food sources diminished. Rats resorted to cannibalism due to hunger, leading to increased aggression and dispersion in search of food. The absence of normal food supplies spurred rats to exhibit bold behavior, including appearing in daylight hours.
Myths and Misconceptions Surrounding Urban Rats
Urban rat myths often exaggerate their size and behaviors. Despite common beliefs, rats do not grow excessively large and are unlikely to pose extreme physical threats to humans. Rats' adaptability and reproductive capacity enable them to quickly rebound from population declines, highlighting their resilience and evolutionary success.
Evolution of Rat Tails and Unique Adaptations
Rats, particularly those found in city areas, have evolved to have sparse hairs on their tail to avoid accumulating debris as they navigate through dirty environments. The unique adaptation of having a scaly tail helps city rats balance on narrow surfaces such as wires and also serves as a thermal regulator to help them regulate body temperature in varying weather conditions.
Rat Teeth Strength and Regional Food Preferences
Rats possess powerful incisors without roots that continuously grow, enabling them to exert high pressure while gnawing. In terms of regional food preferences, studies have shown that rats in different cities may develop distinct food dialects based on the prevalent cuisine in their area. Their ability to adapt to regional food sources influences the efficacy of bait traps for rodent control.
RATS: They love pizza. They invade taquerias at midnight. They scurry. They cuddle. They outsmart. They inspire movies that inspire musicals. Proving that not just woodsy megafauna can be charismatic, rats have lives we would never suspect. Globally-lauded Urban Rodentologist Dr. Robert Corrigan, or Bobby if you like, has been studying these animals in their big-city ecosystem for decades and he is a wonder-filled joy. Learn about rats’ origin story, the difference between a rat and a mouse, where they live, their preferred “food dialects,” and how to (hopefully humanely) keep one out of your house -- or car? Might as well start to love and respect them, because we’re not-too-distantly related and one day… they may be steering the ship.
