Unlike many hirundines, the mangrove swallow is a solitary nester built into nooks near water, either manmade or artificial. These particular birds pictured had made the bold choice to make a nest on one of the tour boats for the Tarcoles River, and thus periodically they would follow their moving nest up and down the river before returning to dock, seemingly unphased.
