Breeding Bird Surveys

Protecting birds and complying with the law

Regulatory permits and environmental impact reports typically include requirements to avoid bird nests in compliance with the California Fish and Game Code and Migratory Bird Treaty Act. Padre biologists conduct pre-activity surveys during the bird breeding season to identify active nests, based on bird behavior and direct sightings of nests. Activities that may affect bird nests may include excavation, construction of structures and maintenance (primarily along channels). Active nests are typically identified and a no-work buffer area is established around the nest in coordination with resource agencies. The size of the no-work buffer is typically based on the intensity of the work activity and the sensitivity of the species involved. Active nests may be monitored by Padre staff to determine when the young have fledged and work may resume near the nest.
