Cliff Swallow and nest – Bear River NWR; Brigham City, Utah: Spaced along the road between the Bear River NWR headquarters and the refuge entrance are numerous information kiosks recently added as part of the refuge renovation plan. Soon after their construction the kiosks became the platform for nesting colonies of cliff swallows. Cliff swallow traditionally built their mud nest under the rock overhangs of cliffs; but soon after humans colonized the New World, cliff swallows adopted manmade structures in addition to those rocky cliffs.
