Many people in urban environments notice adult pigeons but rarely see their young. This absence sparks curiosity, and the perceived disappearance of these young birds stems from their nesting habits, rapid development, and appearance once they leave the nest.
Hidden Nesting Locations
Pigeons, also known as rock doves, are highly adaptable birds that prefer to nest in sheltered, elevated locations, mimicking the cliff faces of their ancestral habitats. In urban settings, they frequently choose secluded spots that are out of sight from human activity. These include the undersides of bridges, hidden ledges on tall buildings, abandoned attics, and even within large ventilation systems.
Such nesting sites offer protection from predators and adverse weather, but they also make it very difficult for people to spot active nests or young birds. The birds build nests from various materials, often tucked deep within these crevices. Consequently, the earliest stages of a pigeon’s life unfold in places rarely accessed or observed by the general public.
Rapid Growth in the Nest
Pigeon squabs, as baby pigeons are called, undergo a surprisingly fast development within the confines of their nest. When they first hatch, squabs are altricial, meaning they are helpless, blind, and covered in sparse, yellowish down. Both parent pigeons participate in feeding the squabs a specialized, nutrient-rich substance called “crop milk,” which is regurgitated from their digestive tracts.
This high-protein diet fuels a very rapid growth spurt. Within approximately three to four weeks, squabs grow substantially, often reaching nearly the full size of an adult. By the time they fledge, they are almost fully feathered and robust, ready for independent life.
Fledglings Resemble Adults
By the time young pigeons leave their nests, they are already large and well-feathered, making them look similar to adult pigeons. Unlike many other bird species where fledglings have distinct juvenile plumage, pigeon fledglings closely mimic the appearance of their parents. Their feathers are generally developed, and their body proportions are similar to mature birds.
Subtle differences might exist, such as duller plumage, a less developed wattle, or a shorter tail. A fledgling might also exhibit less confident flight or clumsy landings compared to an experienced adult. However, these minor distinctions are often not obvious enough for the average observer to identify them as juvenile birds, leading to the common misconception that baby pigeons are never seen.
