Bank swallows (Riparia riparia) are insectivorous songbirds with a distinctive dark brown breast band separating their brown upperparts from their white underparts. Known for their fast, agile flights, these small passerines can be seen buzzing acrobatically through the air along Prince Edward Island’s coasts during the spring and summertime. Bank swallows nest colonially in sandstone cliffs, till bluffs, high sand dunes, and sand pits. As they fly over nearby meadows, wetlands, and agricultural grasslands they forage on insects like beetles, wasps, bees, flying ants, and mayflies. Based on this feeding strategy, bank swallows belong to a guild of birds called aerial insectivores. Like many aerial insectivores, bank swallow populations in Canada are declining due to threats contributing to the loss of their breeding and foraging habitats: land use changes and associated agricultural intensification, and the practice of shoreline armouring. Bank swallow may also be indirectly impacted by pesticide use, which reduces the abundance and availability of their insect prey. In recognition of these threats, bank swallow was listed as a threatened species under the Species at Risk Act (SARA) in 2017.
