When food runs low in the city, pigeon fathers step up. In Munich, researchers watched as male pigeons spent more time warming eggs when meals were scarce—giving their mates a chance to search for food longer. This quiet shift in parenting duties, observed across 75 nests, reveals a surprising flexibility in one of the world’s most familiar urban birds.
Pigeons are often seen as pests, but this study shows they’re also resilient parents. When food is easy to find, female pigeons do most of the incubating—81% of the time—while males sit on the nest just 17%. But when food becomes hard to come by, the balance shifts. Females drop to 75% nest time, their energy running low. Males pick up the slack, increasing their share to 22%. The result? The eggs stay warm, and hatching success remains high, no matter how tough conditions get.
The team from the Technical University of Munich used clever weight sensors under nests to track these changes without disturbing the birds. Some pigeons lived in managed dovecots with steady food; others nested on church roofs and building ledges in cities with feeding bans. These bans are common in urban areas trying to control pigeon numbers, but the study shows they hit females hardest. Well-fed females weighed about 35 grams more—roughly 10% of their body weight—than those struggling to find food. Males showed no such difference, likely because they spend less time on the nest and more time foraging.
"Even under adverse conditions, pigeons are able to successfully hatch their offspring," says Brandon Mak, lead author of the study. But that success comes at a cost. Chicks that hatch into food-scarce environments may not survive long after leaving the nest. The research suggests more humane alternatives, like replacing real eggs with dummy ones, could control populations without forcing birds into starvation.
Professor Wolfgang Weisser, part of the research team, emphasizes the need for thoughtful coexistence: "Living with urban animals requires a deeper understanding of their nuanced behavior, regardless of how we feel about them." As cities grow, so does the need for smart, compassionate wildlife management. Pigeons, it turns out, are not just survivors—they’re teachers, showing us how care and cooperation adapt when times get tough.
