Season - Pigeon Nesting

For those squabs that survive to fledge, the learning curve is steep. They must quickly master the art of finding food, avoiding traffic, and navigating complex urban landscapes. Young pigeons (squabs) are recognizable by their unkept appearance, a fleshy, unpigmented cere (the white bump at the base of the beak), and a general clumsiness. Their first few weeks post-fledging, which still fall within the extended nesting season as parents provide supplemental feeding, are the most dangerous of their lives. For many city dwellers, pigeon nesting season is synonymous with nuisance. Nests clog gutters and air conditioning units, droppings deface architecture, and the cooing of courting males outside a bedroom window can be maddening. Consequently, many municipalities engage in “population control” during the nesting season, including egg oiling (shaking or coating eggs to prevent development) or nest removal. However, because pigeons are determined re-nesters, simply destroying a nest often results in the pair laying a replacement clutch within days, a process that can actually increase their annual reproductive output due to a shorter inter-brood interval.

The most remarkable aspect of pigeon nesting season is its aseasonality in mild climates. In cities like London, New York, or Mumbai, where artificial heat sources (subway vents, heated buildings) and constant food availability negate seasonal extremes, one can find active pigeon nests in every month of the year. This represents a significant evolutionary departure from their wild ancestors, the cliff-dwelling rock doves of coastal Europe and North Africa, who nested primarily in late spring. Domestication and subsequent feral living have effectively decoupled the pigeon’s reproductive clock from the strict photoperiodism (day-length sensing) that governs other birds. The pigeon nest is not a thing of beauty, but it is a testament to practicality. Described by ornithologists as a “flimsy platform,” the typical nest consists of a sparse collection of twigs, straw, grass stems, and an astonishing array of anthropogenic materials: cigarette butts (which may act as natural insecticides due to residual nicotine), bits of plastic, paper clips, string, and even discarded electrical wire. The male initiates nest-building, bringing individual sticks to the female, who arranges them. The entire construction rarely takes more than a day or two. pigeon nesting season

The transition from crop milk to solid food is gradual. After about a week, the parents begin to regurgitate partially digested seeds and grains, mixing them with continuing crop milk. By the third week, the squabs are eating almost entirely adult food, though they still beg vociferously. The pigeon nesting season is characterized not by a single attempt but by a continuous series of broods. A typical breeding pair can produce 4 to 6 broods per year, each consisting of exactly two eggs (clutch size is almost invariantly two). The eggs are white and glossy, incubated for approximately 18 days. Both sexes share incubation duty: the male typically takes the day shift (from late morning to mid-afternoon), while the female broods overnight and in the early morning. For those squabs that survive to fledge, the
