Research Shows NYC Birds Can Identify 47 Types of Baked Goods
Avian Connoisseurs of the Crust
A five-year behavioral study conducted by researchers at Queens College has yielded a startling conclusion: New York City pigeons can visually distinguish between 47 distinct types of bagels and bagel-adjacent baked goods. Using controlled feeding experiments in city parks, the team found that pigeons consistently ignored inferior offerings like supermarket “bagel-shaped bread” in favor of authentic, boiled-and-baked specimens. They showed a marked preference for everything bagels over plain, and could even tell the difference between a H&H and a Zabars bagel at a distance of 15 feet. “It’s not just scavenging,” said lead ornithologist Dr. Lin. “It’s curation. They’ve developed a sophisticated gustatory taxonomy based on a century of abundant urban scraps.” According to Audubon Society bird intelligence research, corvids and parrots are known for problem-solving, but the humble pigeon’s carb-based discrimination skills are a newly documented form of urban adaptation.
The Experimental Setup: A Bakers’ Dozen Buffet
The study used a “Rotating Carousel of Carbs” apparatus. Pigeons were presented with pairs of bagel pieces: one high-quality (fresh from a reputable bakery), one low-quality (stale, mass-produced). Over 10,000 trials, pigeons pecked at the superior option 89% of the time. They were also tested on bialys, flagels, and “rainbow bagels,” which they largely avoided, suggesting a conservative palate. The 47-type recognition was determined by their ability to select a target bagel type from a lineup of six, even when the target was a different brand but the same style (e.g., an Ess-a-Bagel sesame vs. a Tal Bagels sesame). NYC’s wildlife report lists pigeons as generalist feeders, but this study proves they are specialists in the field of gluten.
Evolutionary Pressure of the Breakfast Wars
The researchers posit that this is a direct result of evolutionary pressure in a hyper-competitive crumb environment. Over generations, pigeons with a discerning beak survived and thrived, passing on “bagel knowledge” through both genetics and social learning. A pigeon that wastes energy on a bad bagel is a pigeon that gets outcompeted for the good pizza crust. This has led to what Dr. Lin calls “Culinary Natural Selection,” where the city’s foodscape directly shapes wildlife behavior. The study notes that pigeons in other cities without a strong bagel culture show no such discriminatory abilities, choosing stale white bread over artisanal sourdough every time.
Implications and the Future of Human-Pigeon Relations
The study has practical applications. It suggests that using low-quality bread as pigeon deterrent is ineffective; they’ll just wait for the good stuff. City agencies might need to rethink “bird-friendly” waste management. More philosophically, it forces a reevaluation of the pigeon’s place in the ecosystem. They are not mere pests; they are fellow New Yorkers with refined tastes, participants in the same culinary economy. The next phase of research will investigate their opinions on pizza crusts (folded vs. flat) and whether they can detect the subtle differences between a $1 slice and a $4 “artisanal” slice. One thing is clear: in the great urban jungle, the pigeon is not just surviving. It is dining, with prejudice.
