What characterizes roosting sites for feral pigeons?

Feral pigeons, often found in urban environments, prefer roosting sites that provide shelter from the elements. Such sites offer protection from rain, wind, and extreme temperatures, creating a safer environment for the pigeons to rest and sleep. These sheltered areas can be found in structural ledges, under bridges, or within buildings, which not only provide cover but also security from potential predators. The preference for these protected spots is crucial for their survival and comfort, especially when considering their habits and natural behaviors.

Open and exposed areas, while potentially suitable for temporary perching or foraging, do not provide the safety or comfort required for roosting. Daytime feeding areas are typically distinct from roosting sites, where feral pigeons actively search for food rather than rest. Additionally, the notion that roosting sites are not used during nighttime contradicts the behavior of feral pigeons, which predominantly roost at night for security. Thus, the characteristics of their roosting sites focus heavily on the need for shelter and security.
