Beyond The Branches: The Urban Pigeon Nesting in The Age of Asphalt

Urbanisation has a variety of effects on bird populations due to habitat fragmentation and the availability of nest building materials. This study tracked Columba livia's nest building behaviour from nest site selection to laying egg. Urbanisation alters the native ecosystem, reducing available areas for breeding and other related behaviours such as nest site selection and nest construction material choice. This leads to the usage of atypical nest material, which increases nestling mortality.
